Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates generally to methods and apparatus for exploring subsurface formations. More particularly, the present invention relates to improved techniques for controlling seismic exploration testing and measurement equipment.
2. Background
Geophysical mapping techniques for determining subsurface structures in the Earth include, for example, seismic surveying, magnetotelluric surveying and controlled source electromagnetic surveying, among others. Generally, a variety of different seismic surveying techniques may be used in performing seismic exploration of different physical environments such as land environments and marine environments. Such seismic surveying techniques may include, for example, surface seismic exploration and borehole seismic exploration.
In surface seismic surveying, an array of seismic sensors is deployed at the Earth's surface (or near the water surface or on the water bottom for various types of marine seismic surveying), and one or more seismic energy sources is actuated at or near the Earth's surface in a location near the seismic sensor array. A record is made, indexed with respect to time of actuation of the seismic energy source, of signals corresponding to seismic energy detected by each of the sensors in the array. Seismic energy travels downwardly from the source and is reflected from acoustic impedance boundaries below the Earth's surface. The reflected energy is detected by the sensors. Various techniques are known in the art for determining the structure of the subsurface Earth formations below and/or adjacent to the sensor array from recordings of the signals corresponding to the reflected seismic energy. Other techniques known in the art provide estimates of fluid content in porous Earth formations from characteristics of the reflected energy such as its phase and/or amplitude.
Borehole seismic surveys are typically conducted by placing receivers in a borehole and operating a seismic source at the surface to generate an acoustic wave. Typically the receivers are placed in a shuttle and deployed downhole for the duration of the survey and then removed.
Seismic data are typically collected using an array of seismic sources and seismic receivers. The data may be collected on land using, for example, vibration devices or explosive charges as sources and geophones as receivers; or the data may be collected at sea using, for example, air guns as the sources and hydrophones as the receivers.
FIG. 1A is a schematic illustration of the survey geometry for the method of seismic surveying known as vertical seismic profiling (VSP) surveying. In this surveying geometry, the receiver 1 is not disposed on the earth's surface, but is disposed within the earth, in this example within a borehole 6. The seismic source 2 is disposed on the earth's surface. Two ray paths for seismic energy are shown in FIG. 1. Path 3 is a path in which the seismic energy does not undergo reflection, although it is refracted at the boundary between two layers 7, 8 of the earth. Since seismic energy that travels along this path travels direct from the source 2 to the receiver 1 without reflection, this path is known as the “direct path”. Path 4 is a path in which seismic energy emitted by the source 2 is incident on the receiver 1 after reflection by a reflector 5 located at a greater depth than the receiver, and is thus known as a “reflection path”.
In FIG. 1A the seismic source 2 is located at a distance from the point at which the vertical line on which the receiver 1 is disposed passes through the earth's surface. This geometry is known as offset VSP, since there is a non-zero horizontal distance between the seismic source and the receiver. The horizontal distance between the seismic source and the receiver is generally known as “offset”. In an alternative VSP geometry, the seismic source is located nearly vertically over the receiver, and this is known as zero-offset VSP.
FIG. 1A shows only one seismic source and one receiver, but it is possible for there to be more than one source and/or more than one receiver. In the survey geometry known as multi-offset VSP, a plurality of seismic sources are located on the surface of the earth, with each source having a different offset (i.e., being at a different horizontal distance from the point at which the vertical line on which the receiver 1 is disposed passes through the earth's surface).
A vertical seismic profile (VSP) is a class of borehole seismic measurements used for correlation between surface seismic receivers and wireline logging data. VSPs can be used to tie surface seismic data to well data, providing a useful tie to measured depths. Typically VSPs yield higher resolution data than surface seismic profiles provide. VSPs enable converting seismic data to zero-phase data as well as enable distinguishing primary reflections from multiples. In addition, a VSP is often used for analysis of portions of a formation ahead of the drill bit.
Conventionally, there are a variety of different VSP configurations including zero-offset VSP, offset VSP, walkaway VSP, vertical incidence VSP, salt-proximity VSP, multi-offset VSP, and drill-noise or seismic-while-drilling VSP. Check-shot surveys are similar to VSP in that acoustic receivers are placed in the borehole and a surface source is used to generate an acoustic signal. However, a VSP is a more detailed than a check-shot survey. The VSP receivers are typically more closely spaced than those in a check-shot survey; check-shot surveys may include measurement intervals hundreds of meters apart. Further, a VSP uses the reflected energy contained in the recorded trace at each receiver position as well as the first direct path from source to receiver while the check-shot survey uses only the direct path travel time.
While VSPs can provide valuable information about a formation, source perturbations (e.g. shot to shot variations in the seismic signature of an air gun) introduce error into the raw seismic data which percolates through the processing chain to the final images produced. VSP source perturbations can limit the full range of usefulness that VSPs data can provide. In marine surface seismic acquisitions, these source perturbations can be well controlled through digital gun controllers and processes such as source signal estimation (see, for example, U.S. Pat. Nos. 4,757,482; 5,581,415; 5,995,905; and 4,476,553, which are hereby incorporated by reference in their entirety for all purposes).
FIG. 1B shows an example of a borehole offset VSP measurement scenario in a marine environment in which an offshore rig 100 is positioned over a subsea borehole 102. The borehole 102 includes a plurality of spaced receivers 103 to facilitate, for example, a vertical seismic profile VSP acquisition. When performing borehole offset VSP measurements in a marine environment, a boat 122 is typically used to transport the seismic signal source equipment to a desired location away from the offshore rig 100.
In the example of FIG. 1B, the seismic signal source equipment which is located at the boat includes an air-gun or guns 106 suspended below the surface by a float 108. An analog hydrophone 110 is suspended below the air-gun 106. The hydrophone 110 can provide partial information for correcting time break errors attributable to time differences for swells, irregular source firings, etc. One or more analog lines form part of an umbilical 111 that may also include an air line. The umbilical 111 provides an analog communications/control link between the boat-side seismic survey computer system 124 and the signal source equipment.
Typically, the rig-side seismic survey computer system 120 and the boat-side seismic survey computer system 124 are initially configured with desired operating parameters before deployment in the field. Once the computer systems have been deployed in the field, a human technician is stationed at each system to operate their respective equipment in order to carry out seismic survey measurements. Communication between the rig-side seismic survey computer system and the boat-side seismic survey computer system is typically implemented using an analog radio communication link.
Conventionally, rig-side seismic survey computer systems and boat-side seismic survey computer systems do not include functionality for enabling remote configuration or modification of their operating parameters. Thus, for example, when the rig-side technician (stationed at the rig-side seismic survey computer system) desires to modify an operating parameter at the boat-side seismic survey computer system, the rig-side technician is required to communicate (typically via radio communication) with the boat-side technician in order to instruct the boat-side technician to modify the desired parameter(s) at the boat-side seismic survey computer system. The boat-side technician is then responsible for implementing the specified parameter modifications at the boat-side seismic survey computer system.
Moreover, due to the complexity of seismic source control operations, conventional source control systems provide only limited quality control (QC) features, and provide only limited functionality for controlling source control equipment, especially for remote source signal and large source arrays. Accordingly, it will be appreciated that there exists a need for improving seismic survey measurement techniques and equipment.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As described in greater detail below, the technique of the present invention provides a variety of novel features which may be used for improving seismic survey measurement techniques.
According to at least one embodiment of the present invention, a new digital seismic source controller graphical user interface (GUI) may be implemented at the rig-side seismic survey computer system, remote-side (e.g., boat-side) seismic survey computer system, and/or other seismic survey computer systems. In at least one implementation, the seismic source controller GUI may include a plurality of different windows, each of which provides functionality for improved source control functionality. Such windows may include, for example: (1) a Main Window which provides for radio modem communication parameter control, Ethernet communication parameter control, master/slave connection control, database control, access to other sub windows, etc.; (2) a Fire Control Window which provides functionality for fire control configuration, source enable/disable control, system health check & sensor calibration, system mode selection, sensor reading monitor, sub system booting, etc.; (3) a Quality Control Window which provides function only for presenting QC plots such as, for example, source signature plots, source signature frequency plots, source tuning plots, source solenoid current plots, overlaid plots, tuning error history plots, source delay history plots, source depth plots, source pressure plots, etc.; (4) an Error Report Window which provides function only for displaying error messages relating to one or more of the seismic survey computer systems; (5) a System Configuration Window which provides functionality for local and/or remote configuration and/or modification of fire control parameters, source control setup and operating parameters, and configuration element setup and operating parameters, etc.
One of the unique features of the present invention is its ability to allow each source control system to be independently configured as a master or slave. In at least one implementation, a master system may be provided with the capability of partial remote control of the slave system and slave system operating parameters, including, for example, parameter modification, test firing, slave system assignment and selection, etc. In at least one embodiment, a master system may be configured or designed to control a plurality of slave systems.
FIG. 2 shows a simplified block diagram of various components, systems, and/or devices which may be used for performing offset seismic surveying operations in accordance with the specific embodiment of the present invention. According to a specific embodiment, block portion 201 may represent seismic survey equipment deployed at the offshore rig 100 (FIG. 1B), and block 203 may represent seismic survey equipment deployed at the boat 122. As illustrated in the example of FIG. 2, block portion 201 may include one or more of the following components: a GPS system 208 a, a seismic navigation and positioning system 206 a (also referred to as SWINGS), a source control system 210 a (e.g., Trisor digital source control system, manufactured by WesternGeco-Fjord Instruments Inc.), a UHF radio 214 a, a wire line tool control system 204 (e.g., MAXIS control system available from Schlumberger Technology Corporation), a patch panel system 220 a, a wireless LAN transceiver 216 a, etc. In specific implementations, block portion 201 may optionally include gun array 212 a, and may include at least one versatile seismic imager (VSI) 202, and/or other seismic surveying equipment.
As illustrated in FIG. 2, block portion 203 may include one or more of the following components: a GPS system 208 b, a seismic navigation and positioning system 206 b, a source control system 210 b, a UHF radio 214 b, a patch panel system 220 b, a wireless LAN transceiver 216 b, at least one gun array 212 b, etc.
It will be appreciated that alternate embodiments of the present invention (not shown) may include additional components not illustrated in FIG. 2, and/or may omit one or more components which are illustrated in the specific embodiment of FIG. 2.
FIG. 3 shows a flow diagram of a Seismic Source Controller Setup Procedure 300 in accordance with the specific embodiment of the present invention. According to at least one embodiment, the Seismic Source Controller Setup Procedure 300 may be implemented at the rig-side seismic survey computer system and/or remote-side seismic survey computer system. Initially, as illustrated at 302, the master and slave seismic source controller systems are identified, for example, by a human technician. In at least one embodiment, each source control system 210 a, 210 b may be initialized as a master or a slave. This is shown for example, in FIG. 5 of the drawings, which illustrates a specific embodiment of a Set Master/Slave Configuration dialogue box 500. According to a specific embodiment, dialogue box 500 may be displayed at each source control system upon startup in order to set master/slave configurations. In one implementation, a system may automatically default to being configured as a slave unless it has been designated as a master.
In a specific implementation, the rig-side source control system 210 a may be configured at startup as a master, and the remote-side system 210 b may be configured at startup as a slave (304, FIG. 3). Once the appropriate source control systems have been configured as master or slave, communication may then be established 306 between the master and selected slave(s). This is shown, for example, in FIG. 7 of the drawings, which illustrates a specific embodiment of a Slave Connection dialogue box 700. According to a specific implementation, both the master system and the slave system may be configured to be able to initiate communication between each other.
As illustrated in the Slave Connection dialogue box of FIG. 7, the master system GUI provides the capability of allowing the master system to connect to one or more desired slave systems (e.g., Remote A slave, Remote B slave, etc.). Once communication between the master and desired slave systems has been established, seismic survey measurements may then be performed (308, FIG. 3) using the master/slave configured systems.
According to a specific embodiment, once the master and a slave are connected, the slave will be fully visible on the master. The master is then able to perform a variety of tasks relating to slave operation and control such as, for example:

- a) Displaying and/or changing the current slave system operating mode.
- b) Plotting and displaying data that is received at the slave system. According to a specific embodiment, the master system may be configured to display QC plots and/or sensor signal readings which may normally be displayed at the slave system. Additionally, the master system may be configured to record the data into a database which is stored at the master system.
- c) Generating slave Tape Header information for wireline tool control system. According to a specific embodiment, the master system may be configured to generate and process, in real-time, QC data received from the slave system, and then send the processed QC data (typically referred to as “Tape Header”) to the wireline tool control system in real-time.
- d) Controlling firing the guns.
- e) Changing Gun parameters. According to a specific embodiment, the master system may be configured to remotely change tuning and/or gun parameters at the slave system such as, for example, blanking intervals, manual delay, gun pulse width, pick polarity, filter method, etc.

According to a specific embodiment, the master source control system may be connected directly to the wireline tool control system 204 using, for example, using a LAN connection (e.g., an Ethernet connection). Additionally, the slave source control system may be connected to the seismic navigation and positioning system 206 b using, for example, a wired LAN connection.
According to a specific embodiment, data may be collected by components of the remote-side system and saved in a database located at the remote-side system or, alternatively, at the rig-side system. Additionally, in at least one implementation, data may also be collected by components of the rig-side system and stored in a local database such as, for example, a database located at the source control system 210 a.
In at least one implementation where the rig-side source control system 210 a is configured as the master and the remote-side source control system 210 b is configured as the slave, the source control system slave 210 b may be configured or designed to collect and save data in a manner similar to that of the source control system master. Additionally, in at least one embodiment, the slave system(s) may be configured to communicate with the master system via radio modems (e.g., 214 a, 214 b) and/or wireless LAN transceivers (e.g., 216 a, 216 b). This is shown, for example, in FIG. 6 of the drawings, which illustrates a specific embodiment of a Slave Link Communication dialogue box 600. In the example of FIG. 6, the master system GUI is configured to provide a user with the ability to select the mode of communication between the master system and each of the slave systems. Thus, for example, using the dialogue box 600, a user may configure the master system to communicate with Remote A slave system via wireless LAN 602, and may configure the master system to communicate with Remote B slave system via radio 604.
Communication via radio modems provides relatively low bandwidth such as, for example, up to 100 kbps. In contrast, communication via wireless LAN transceivers provides relatively high bandwidth such as, for example, up to 54 Mbps. Moreover, unlike conventional techniques which provide for an analog communication link between the rig-side seismic survey system and boat-side seismic survey system, the technique of the present invention provides for a digital communication between the rig-side seismic survey system and boat-side (or remote-side) seismic survey system(s). In this way, digital seismic survey data and digital source control information may be digitally transmitted between the rig-side seismic survey system and desired remote-side seismic survey system(s). As a result, the seismic source control system and GUI of the present invention are able to provide a number of benefits and advantages over conventional seismic source control systems.
For example, the technique of the present invention provides for improved source signal firing timing accuracy. Using conventional techniques, source signal firing timing accuracy generally has an associated tolerance within the order of milliseconds. This is primarily due to the fact that conventional source signal timing synchronization is implemented the between the master and remote signal source(s) using analog radio communication techniques which include an inherent radio delay factor. In contrast, the technique of the present invention may be used to improve the tolerance of timing accuracy and synchronization of the firing of the signal source(s) to within the order of microseconds. According to at least one implementation, the improved source signal timing accuracy of the present invention may be attributable to a combination of factors such as, for example, the use of GPS timing synchronization at the rig-side seismic survey computer system and remote-side seismic survey computer system(s), the use of a digital communication link between the rig-side seismic survey computer system and remote-side seismic survey computer system(s), etc.
Another advantage of the present invention is that a provides for improved quality control information and analysis during seismic survey measurement operations. According to at least one implementation, a Quality Control Window may be used to plot, in real-time, desired data, including real-time data collected during the seismic survey measurement operations. In a specific implementation, the Quality Control Window may include a plurality of different tabs relating to different types of sensors, such as, for example, Near Field Hydrophone (NFH), NFH Frequency, Gun, Current, Overlay, Tuning Error, Gun Delay, Depth, Manifold Pressure, etc. According to a specific embodiment, the Gun tab window may display signals from gun TB (Time Break) sensors for individual guns. The Current tab window may display information relating to gun solenoid currents for individual guns. The Overlay tab window may display, for example, NFH, Gun, and/or Current plots in the same window and time scale in order to facilitate comparison of the timing relationship of these signals. Data which is collected at the rig-side seismic survey computer system and/or data which is transmitted from the remote-side seismic survey computer system may be processed for QC analysis, and plotted. It is also possible to plot information relating to source signal fire control characteristics.
FIGS. 9-12 illustrate examples of various types of quality control information which may be displayed using a specific embodiment of the Quality Control Window of the present invention. For example, FIG. 9 shows a graphical illustration of real-time data relating to the source signal signature, which is displayed, for example, as a function of pressure v. time. FIG. 10 shows a graphical illustration of other real-time data relating to the source signal signature, which is displayed as a function of signal strength v. frequency. FIG. 11 shows a graphical illustration of real-time data relating to source timing signal device characteristics (e.g., air gun time break sensor signals, etc.) for selected guns, which is displayed, for example, as a function of normalized electrical voltage (%) v. time. FIG. 12 shows a graphical illustration of real-time data relating to other source signal device characteristics (e.g., air gun solenoid current characteristics, etc.) for selected guns, which is displayed as a function of electrical current v. time.
It will be appreciated that the present invention allows for various types of information to be analyzed and displayed for quality control analysis, including real-time data collected during the seismic survey measurement operations. Moreover, unlike conventional techniques, the technique of the present invention is able to provide improved quality control analysis functionality by providing high resolution displays of real-time QC data. Such high resolution displays of real-time QC data has traditionally been unavailable to conventional offset seismic survey systems. One reason for this is due to the fact that conventional offset seismic survey systems utilized a low bandwidth analog radio communication link to communicate between the rig-side seismic survey system and boat-side seismic survey system. However, as described previously, specific embodiments of the seismic survey systems of the present invention are able to be configured or designed to utilize a high bandwidth digital communication link to communicate between the rig-side seismic survey system and the remote-side seismic survey system. The use of a high bandwidth digital communication link between the rig-side seismic survey system and the remote-side seismic survey system allows for improved quality control analysis functionality, for example, by enabling high bandwidth communication of seismic survey measurement information, signal source information, and/or other QC information between the rig-side seismic survey system and the remote-side seismic survey system, which, in turn, allows for high resolution real-time QC information (such as that shown, for example, in FIGS. 9-12 of the drawings) to be displayed to the user.
In addition, the use of a high bandwidth digital communication link between the seismic survey computer systems of the present invention allows for shorter cycle time between seismic survey measurements. For example, the average cycle time for conventional offset seismic survey systems is about 10-15 seconds. In contrast, the average cycle time for offset seismic survey systems of the present invention is up to about 5 seconds.
Another advantageous feature which the seismic survey system of the present invention provides over conventional seismic survey systems is the ability to remotely monitor, control and modify desired parameters at the remote-side seismic survey system, particularly in response to QC analysis of previous seismic survey measurements.
FIG. 4 shows an example of a flow diagram 400 illustrating a specific embodiment of how various information may be used to determine and dynamically modify desired parameters at a remote-side seismic survey system. Initially, in this example, it is assumed that at least one seismic survey measurement has been performed using the seismic survey equipment illustrated in FIG. 1B. As shown in FIG. 4, seismic survey measurement information (such as that recorded by receivers 103) is received (10) at the Wireline Tool Control System (204, FIG. 2) which is connected to the master seismic survey computer system 402. Additionally, source signal quality control information is transmitted (12) from the slave seismic survey system 404 to the master 402. At least a portion of the received information is then analyzed (14) using one or more of the above-described quality control analysis techniques and/or other quality control analysis techniques commonly known to one having ordinary skill in the art. In at least one embodiment, the QC analysis of the received information may be used to determine (16) desired parameter adjustment information relating to one or more of the devices associated with the slave seismic survey system. According to one embodiment, a human technician may utilize the analyzed QC information in order to generate desired parameter adjustment values for the slave system. In an alternate embodiment, at least a portion of the parameter adjustment values may be automatically generated and/or recommended by hardware and/or software components associated with the master system. Examples of different parameters of the slave system which may be remotely modified via the master system are illustrated in FIGS. 13-19 of the drawings.
Once the appropriate slave system parameter adjustment information has been determined, the parameter adjustment information is transmitted (18) to the slave system. Using the received parameter adjustment information, the slave system 404 may then automatically update and/or modify (20) appropriate parameter values at the slave system. According to a specific embodiment, the updating or modification of the parameter values at the slave seismic survey system may be performed in real-time and without the need for a human operator or technician to implement the parameter value modifications at the slave system. Additional seismic survey measurements may then be performed using the modified slave system parameter values. At least a portion of the measured data obtained during the additional seismic survey operations may then be transmitted to the master system 402 in order, for example, to perform additional QC analysis and/or parameter adjustments.
According to at least one implementation, the GUI of the present invention may include a Fire Control Window for facilitating remote parameter adjustment of the slave system. In one implementation, the Fire Control Window may be configured or designed to allow a user to perform various functions including, for example, loading desired configuration files and displaying visual models of the configuration parameters; remotely selecting the operating mode of the slave system (such as, for example, Control System Mode, Safe Mode, Test Mode, Offline Mode, Online Mode, etc.); remotely preparing, testing and/or controlling the slave system; displaying real-time data from the slave system sensors; etc. According to a specific embodiment, the configuration files may be implemented as files which model the remote-side hardware configuration(s) which, for example, may include information relating to settings, parameters and/or other information required for operating the source control system(s).
In a specific implementation, the Fire Control Window may be configured or designed to provide a variety of different pull-down menus which may be used to provide additional functionality. For example, a View menu may be used to select desired status information to be displayed to the user, for example, via the Fire Control Window GUI. Such information may include, for example, signal source device information (e.g., gun information), sensor information (e.g., NFH sensors, depth sensors, manifold sensors, etc.), communication information (e.g., fire pulse channel information), etc. An example of different types of status information which may be displayed his illustrated in FIG. 20 of the drawings. FIG. 20 shows a specific embodiment of a GUI 2000 which may be used for displaying various status information associated with the slave seismic survey system. At least one embodiment, the information displayed in FIG. 20 represents real-time information which may be obtained from the slave system and displayed in real-time on the master system.
FIGS. 13-19 illustrate specific embodiments of various GUIs of the present invention which may be used to enable a user of a master seismic survey system to remotely modify parameters associated with one or more slave seismic survey systems. Each of these figures will now be discussed in brief detail in order to describe at least some of the various parameters of the slave system which may be remotely modified using the technique of the present invention.
FIG. 13 shows a specific embodiment of a GUI 1300 which may be used for remotely modifying NFH parameters such as, for example, sensitivity, gain, distance from NFH to signal source, etc.
FIG. 14 shows a specific embodiment of a GUI 1400 which may be used for remotely modifying source depth sensor parameters such as, for example, nominal depth, tolerance around nominal depth, distance from depth sensor to signal source, etc.
FIG. 15 shows a specific embodiment of a GUI 1500 which may be used for remotely modifying manifold sensor parameters such as, for example, low pressure alarm, high pressure alarm, etc.
FIG. 16 shows a specific embodiment of a GUI 1600 which may be used for remotely modifying source signal tuning parameters such as, for example, pick threshold, fire threshold, gun AF (Auto Fire) threshold, filter length, pick method, filter method, etc.
FIG. 17 shows a specific embodiment of a GUI 1700 which may be used for remotely modifying additional source signal tuning parameters such as, for example, max delay, step change, step toggle, signature length, offset, error range, gun volume, max allowable gun delay, etc.
FIG. 18 shows a specific embodiment of a GUI 1800 which may be used for remotely modifying selected source signal device (e.g., gun) parameters such as, for example, blanking interval, manual delay, gun pulse width, pick polarity, etc.
FIG. 19 shows a specific embodiment of a GUI 1900 which may be used for remotely implementing manual tuning of source signal device (e.g., gun) parameters such as, for example, blanking interval, manual delay, gun pulse width, polarity selection, filter method, etc. According to one embodiment, the parameter values for the manual tuning of the source signal device may be manually entered into the appropriate boxes of the manual tuning GUI 1900. Alternatively, in at least one embodiment, computer implemented software and/or hardware may be used to automatically suggest parameter values for the manual tuning of the source signal device. For example, in one implementation, when a user at the master system attempts to perform manual tuning of a gun located at the boat-side system, a dialog box may be designed to pop up and suggest at least one preferred value for the parameter to be adjusted. The user may then choose to reject the suggested value(s), or, alternatively may choose to accept the suggested value. This feature of providing computer implemented suggestions of desired values is advantageous in that it facilitates manual tuning of source signal devices even in situations, for example, where there are source time break sensor device failures. In a specific implementation, the suggested values may correspond to preferred default values, previously known actual working values, etc.
The following example is intended to help illustrate of various aspects of the present invention may be used to overcome problems encountered during offset seismic survey measurement operations. In this example, it is assumed that a seismic engineer stationed at the rig (100, FIG. 1B) is monitoring the display of QC analysis information at the rig-side seismic survey computer system. Further, it is assumed that the wireline tool control system reports detection of the occurrence of a gun tuning error for Gun#1 which is associated with the boat-side seismic survey system. In this example, there is a high degree of noise on the sensor signal for Gun#1. In order to reduce or eliminate such noise, the engineer may use the master system to access the slave system in order to change the operating mode at the slave system to Safe mode, and then use the Fire Control Window GUI to change the blanking interval parameters for Gun#1. Thereafter, the engineer may switch the operating mode of the slave system to Offline mode, and then manual fire Gun#1 in order to determine whether the noise condition has improved. Once the tuning error (e.g., noise condition on Gun#1) has satisfactorily improved, the engineer may then switch the operating mode of the slave system to Online mode, and then continue with subsequent seismic survey measurement operations.
According to a specific embodiment, a System Configuration Window may be provided for enabling a user at the master system to create and transmit configuration files and/or parameter adjustment information for use at the slave system. During the transfer of the configuration files and/or parameter adjustment information from the master system to the slave system, a separate Remote Configuration Dialog Window may be displayed for monitoring the status or progress of the master/slave synchronization. An example of a Remote Configuration Dialog Window is illustrated in FIG. 8 of the drawings. As illustrated in the example of FIG. 8, checkboxes in the Remote Configuration Dialog Window may be automatically checked upon the completion of specific tasks. In this way, the user may be notified, in real-time, of the current status of the master/slave synchronization. In at least one embodiment, an Error Window may be provided for displaying error messages and/or status messages reported by the TPMs (Trisor Processor Modules) and/or other hardware/software in the seismic survey systems.
According to a specific embodiment, the method of communication between the master source control system and the slave source control system may be controlled from either the master or slave from the Main Window of the GUI. In at least one implementation, the Main Window of the GUI may be configured as the main application in the source control system. This application may store desired data and communicates with the local and remote database(s). It may also communicate with the remote-side systems and other GUI applications.
