Definitions
- the invention relates to a method of drilling a well borehole which encompasses using water-base drilling fluids and spotting fluids.
- the fluids contain the reaction products of a polycarboxylic acylating agent and an amine-terminated polyoxyalkylene.
- the primary functions of a drilling fluid or mud are: to carry chips and cuttings produced by drilling to the surface; to lubricate and cool the drill bit and drill string; to form a filter cake which obstructs filtrate invasion in the formation; to maintain the walls of the borehole; to control formation pressures and prevent lost returns; to suspend cuttings during rig shutdowns; and to protect the formation for later successful completion and production.
- Sticking of the drill pipe during the drilling is a common problem. This condition is commonly referred to as being a stuck pipe. Spotting fluids or stuck pipe fluids are generally used to free the drill pipe so that drilling may continue. Oil-base drilling fluids are commonly used to prevent stuck pipe. However, these fluids contain refined mineral oils or diesel fuels which adversely effect marine life. It is desirable to have drilling fluids and spotting fluids which are effective and yet do not adversely impact the environment.
- Re. 30,885 which is a reissue of U.S. Patent 4,239,635 relates to diamides and lubricants containing the same.
- the carboxylic acid terminated acid diamides and alkali metal, ammonium or amine salts thereof have lubrieating properties and are especially useful in aqueous metal-working fluids.
- Re. 31,522 which is a reissue of U.S. Patent 4,374,741, relates to polyamides and functional fluids containing the same.
- the polyamides are polyoxylene polyamides having a terminal carboxylic acid group and terminal amine group in the same molecule and the degree of polymerization of 210 and salts thereof are useful in preparing stable aqueous based metal-working and hydraulic fluids.

- U.S. Patent 4,795,581 relates to aqueous fluids thickened with fatty acid modified polyoxyalkylene diamines. These materials are useful for water/glycol based hydraulic fluids, cosmetics and surfactants.
- the present invention relates to a method, comprising the steps of:
- compositions comprising water and an amount, sufficient to reduce drilling torque, prevent sticking or twisting of a pipe during drilling, or release a stuck pipe in a well borehole, of (A) at least one reaction product of (A-1) at least one carboxylic acylating agent and (A-2) at least one amine- terminated polyoxyalkylene having a number average molecular weight from about 600 to about 10,000, or at least one salt of the reaction product, and drilling the well borehole.

- the concentrates are generally diluted with water at a level of about 0.5% to about 15% concentrate in water.
- the water may be fresh or salt water.
- the concentrate is used from about 1%, preferably from about 3% to about 10%, preferably to about 7%, usually to about 5% by weight concentrate in water.
- Table 3 contains spotting fluid concentrates. Spotting fluids may be prepared from these concentrations by mixing 5% of the concentrate in fresh or salt water.
- the sticking test measures the time necessary for the spotting fluid to unstick a plate.
- Table l are tested using a base mud containing 22 pounds per barrel of bentonite (Aquagel) and 30 pounds per barrel of Martin No. 5 bulk clay which is mixed with water. This mixture is statically aged for 72 hours. Lignosulfonate (Q-broxin) is then added and caustic soda (sodium hydroxide) is added until the pH is about 10.
- Sticking tests are run using a Baroid differential sticking tester apparatus (No. 21150) available from Baroid Co., Houston, Texas U.S.A. The apparatus has been modified by drilling two holes in the cell to allow entrance and exit of spotting fluid.
- the apparatus also uses a bevelled torque plate (Exxon designed torque plate) to establish the height of the filter cake. Modifications of the apparatus are made by Core Laboratories, Lafayette, Louisiana U.S.A. The general procedure involves placing a filter paper and ring attachment in the sticking cell. Approximately 80 milliliters of drilling fluid is poured into the cell. The top of the cell is screwed on and tightened then a yoke attachment is placed on the cell and the desired plate height (cake thickness) is set to 1/64 inch. The cell is pressurized with nitrogen to 500 psi. Filtrate is collected on the filter paper and the plate is allowed to stick. Spotting fluid is added to the cell.
- a bevelled torque plate Exxon designed torque plate
- the cell is inverted and rocked back and forth several times. Any air contained in the cell is bled off. The cell remains inverted after spotting. The time for the cake to unstick is measured. The products are tested at a concentration of 5% by weight in sea water.
- the 96 hour shrimp test is performed on a drilling fluid containing 5% by volume of the spotting fluid.
- the drilling fluid has a pH of 8.46.
- the drilling fluid is thoroughly homogenized for 30 minutes with a high shear mixer.
- the homogenized material is then combined with artificial sea water (salinity equals 20 parts per 1000) in a 1:9 ratio by volume.
- the drilling fluid-sea water mixture characterized by a pH of 7.99, is mixed for five minutes and is allowed to settle for one hour.
- the pH is adjusted with 0.05 milliliter of 6 normal hydrochloric acid to about pH 7.8. Following the settling period, the suspended particulate phase is decanted.
- Mysids (Mysidopsis bahia) used as test organisms are 3-6 days old. The animals are cultured in Core Laboratories Bioassay facilities using brood stock originally purchased from a commercial supplier. The test is conducted at 20°C using artificial sea water (Hawaiian Marine Mix) adjusted to salinity of 20 parts per 1000. Mysids are fed approximately 50 live artemia sp (brine shrimp) per test animal every 24 hours.
- Tests are conducted with five concentrations of suspended particulate phase and a control (of sea water only) with ten Mysids randomly distributed among each concentration. Tests are performed in crystallizing dishes which contain one liter of test solution. Filtered artificial sea water with a salinity of 20 parts per 1000 is used to dilute the suspended particulate phase to test concentrations and as the control solution. A 14 hour light and 10 hour dark photo period is maintained with cool, white flourescent lights. Air is supplied to the test chambers by a commercial aqua culture blower and delivered through glass tubing at a rate of between 50 and 140 cubic centimeters per minute. At a minimum, the number of survivors are determined at 0 and 96 hours. Ninety percent or greater survival occurred in the control exposure.
- the 96 hour reference toxicant test (sodium lauryl sulfate, for this bio essay) is performed according to US EPA protocol.
- the sodium lauryl sulfate is obtained from Aldrich Chemical Co. and is from their lot no. 15K-R- 4G.
- the LC 50 obtained with this most recent sodium lauryl sulfate reference test is 11.5 parts per million sodium lauryl sulfate with 95% confidence level of 10.2 parts per million to 12.9 parts per million.
- the following table contains results of tests performed in the stickometer test and the 96 hour shrimp test.
