Definitions
- the present invention relates to a wellbore screen for controlling inflow of solid particles into a wellbore, the wellbore screen comprising a conduit for transporting fluid and an outer layer comprising a filter for filtering solid particles from fluid flowing into the conduit.
- Stand-alone sand exclusion systems such as slotted liners or a wire-wrapped screens, are generally applied in wells for producing a stream of fluid from the earth formation and wells for injecting a stream of fluid into the earth formation.
- the produced and/or injected stream of fluid can be, for example, oil, gas or water.
- a frequently occurring problem in using such sand exclusion system relates to axial flow of fluid in the annular space between the wellbore wall and the screen. Solids from the surrounding formation which flow with the stream of fluid into the wellbore are thereby transported along the screen and deposited as a layer of very low permeability on the screen. The problem is particularly- pronounced in case clay particles enter the wellbore.
- a wellbore screen for controlling inflow of solid particles into a wellbore
- the wellbore screen comprising a conduit for transporting fluid, an outer layer comprising a filter for reducing inflow of solid particles into the conduit, the outer layer extending around the conduit and being radially expandable against the wellbore wall, and swelling means arranged between the conduit and the outer layer, the swelling means being susceptible of swelling upon contact with a selected fluid so as to radially expand the outer layer against the wellbore wall.
- Solid particles which locally enter the wellbore are thereby prevented from flowing in longitudinal direction along the entire screen so that the risk of plugging of the entire filter as a result of local inflow of solids is eliminated.
- the expanded outer layer supports the wellbore wall so that sand failure at the wellbore wall is largely reduced.
- the expanded outer layer provides a large inflow area for the screen.
- the wellbore can be, for example, a production well for the production of hydrocarbon fluid (crude oil or gas) or water.
- the wellbore can be an injection well for injecting water, oil, gas, waste fluid or another fluid into the earth formation.
- the selected fluid which causes swelling of the swelling means can be a produced fluid, such as hydrocarbon fluid or water, or an injected fluid such as hydrocarbon fluid (e.g. crude oil, diesel or gas) or water.
- fast activation can be achieved by pumping a hydrocarbon fluid, such as diesel, into the wellbore to induce fast swelling of the swelling means. Once fast swelling is achieved, swelling is maintained by virtue of contact of the swelling means with produced hydrocarbon fluid.
- a hydrocarbon fluid such as diesel
- the swelling means includes a plurality of swelleable rings, each ring extending around the conduit and being susceptible of swelling upon contact with the selected fluid, the rings being mutually spaced along the conduit, for example at regular mutual spacings.
- the swelling means includes a sleeve extending around the conduit, the sleeve being provided with a plurality of through-openings spaced along the sleeve, for example through-opening having a substantially rectangular shape or a substantially circular shape.
- the swelling means includes a material susceptible of swelling upon contact with hydrocarbon fluid or water.
- the material for example is a rubber selected from NBR, HNBR, XNBR, FKM, FFKM, TFE/P or EPDM base rubber.
- the material preferably includes a rubber selected from natural rubber, nitrile rubber, hydrogenated nitrile rubber, acrylate butadiene rubber, poly acrylate rubber, butyl rubber, brominated butyl rubber, chlorinated butyl rubber, chlorinated polyethylene, neoprene rubber, styrene butadiene copolymer rubber, sulphonated polyethylene, ethylene acrylate rubber, epichlorohydrin ethylene oxide copolymer, ethylene-propylene-copolymer ⁇ peroxide crosslinked) , ethylene-propylene-copolymer (sulphur crosslinked) , ethylene-propylene-diene terpolymer rubber, ethylene vinyl acetate copolymer, fluoro rubber, fluoro rubber, fluor
- said material is selected from EP(D)M rubber (ethylene-propylene-copolymer, either peroxide or sulphur crosslinked) , EPT rubber (ethylene-propylene- diene terpolymer rubber) , butyl rubber, brominated butyl rubber, chlorinated butyl rubber, and chlorinated polyethylene.
- EP(D)M rubber ethylene-propylene-copolymer, either peroxide or sulphur crosslinked
- EPT rubber ethylene-propylene- diene terpolymer rubber
- butyl rubber brominated butyl rubber, chlorinated butyl rubber, and chlorinated polyethylene.
- the outer layer includes an annular filter layer and an annular shroud extending around the annular filter layer.
- Fig. 1 schematically shows a longitudinal view in section of an embodiment of a wellbore screen according to the invention, before swelling of the swelling means;
- Fig. 2 schematically shows a longitudinal view in section of the embodiment of Fig. 1, after swelling of the swelling means;
- Fig. 3 schematically shows cross-section 3-3 of Fig. 1;
- Fig. 4 schematically shows cross-section 4-4 of Fig. 2.
- like reference signs relate to like components.
- a wellbore screen 1 arranged in a wellbore 2 for the production of hydrocarbon fluid.
- the screen 1 comprises a tubular member 3, a permeable annular outer layer 4 extending at a radial distance around the tubular member 3, the outer layer 4 being formed of a filter layer 4a and a shroud 4b at the outside of the filter layer 4a, and a plurality of swelleable elements in the form of rings 6 arranged between the tubular member 3 and the outer layer 4.
- the rings 6 are arranged at regular spacings along the tubular member 3.
- the outer layer 4 is flexible and radially expandable to at least an expansion ratio whereby the shroud 4b contacts the wellbore wall.
- the filter layer 4a has a sieve opening size adapted to prevent flow of solid particles into the tubular member 3.
- the rings 6 are made of an elastomer which swells upon contact with hydrocarbon fluid, the elastomer being for example EPDM rubber.
- the tubular member 3 has a plurality of perforations 7 for inflow of produced hydrocarbon fluid into the tubular member 3, and is at it ends provided with respective connector portions 8, 10 for interconnecting the wellbore screen 1 to a conduit 9 for transporting produced hydrocarbon fluid to surface.
- Fig. 1 is shown the wellbore screen 1 before swelling of the rings 6 upon contact with produced hydrocarbon fluid, so that the outer layer 4 is in its unexpanded state whereby a clearance 11 exists between the shroud 4b and the wellbore wall.
- Fig. 2 is shown the wellbore screen 1 after swelling of the rings 6 upon contact with hydrocarbon fluid, whereby the outer layer 4 has been radially expanded by the swelling rings 6 so that the annular shroud 4b contacts the wall of the wellbore 2.
- Fig. 3 is shown the wellbore screen 1 and wellbore 2 in cross-section before swelling of the rings 6.
- the filter layer 4a is formed of a plurality of mutually overlapping filter sheets 5.
- Each filter sheet 5 is at one end thereof connected to one or more of the rings 6 by a respective lug 14, and overlaps with an adjacent filter sheet 5.
- the shroud 4b is a thin metal sleeve provided with a mesh of longitudinal slots (not shown) overlapping in longitudinal direction which renders the shroud 4b extremely flexible to radial expansion while providing adequate protection to the filter layer 4a.
- FIG. 4 there is shown the wellbore screen 1 and wellbore 2 in cross-section after swelling of the rings 6.
- the outer layer 4 has been expanded against the wellbore wall, whereby during expansion of the filter layer 4a sliding of adjacent filter sheets 5 relative each other has occurred, and whereby during expansion of the shroud 4b widening of the slots of the shroud 4b has occurred.
- the wellbore screen 1 is lowered into the wellbore 2 and positioned in the hydrocarbon fluid bearing zone of the surrounding formation, whereby the rings 6 are in their respective un-swollen state and the clearance 11 is present between the outer layer 4 and the wall of the wellbore 2 (Fig. 1) .
- a stream of crude oil flows from the surrounding formation into the wellbore 2 and from there via the outer layer 4 and the perforations 7 into the tubular member 3.
- the stream of hydrocarbon fluid flows along the rings 6 which thereby swell from their unexpanded state (Fig. 1) to their expanded state
- Fig. 2 Upon swelling, the rings 6 push in radially outward direction against the outer layer 4 which as a result thereof is expanded against the wall of the wellbore 2. Since the swelling force exerted by the set of rings is distributed along the length of the outer layer 4, the outer layer 4, after expansion thereof, will be substantially compliant with the larger irregularities of the wellbore wall.
- the sieve opening size of the filter layer 4a does not change by the radial expansion since during expansion of the filter layer 4a the individual filter sheets 5 slide relative to each other so that the amount of overlap of adjacent filter sheets 5 decreases.
- the degree of overlap of adjacent filter sheets 5 is selected so that after expansion of the filter layer 4a sufficient overlap of the filter sheets 5 remains to ensure that no open spots occur which could allow fluid to bypass the filter layer 4a.
- accelerated swelling of the rings 6 can be achieved by pumping diesel, or any other suitable fluid, into the wellbore 2 before the well is taken in production.
- the stream of hydrocarbon fluid is prevented from flowing in axial direction along the outside of the outer layer 4 so that sand or clay particles which may have locally entered into the stream of hydrocarbon fluid, are prevented from flowing in longitudinal direction along the entire outer layer 4.
- sand or clay particles which may have locally entered into the stream of hydrocarbon fluid, are prevented from flowing in longitudinal direction along the entire outer layer 4.
- Additional advantages of the wellbore screen relate to the solid pre-drilled tubular member which has a high collapse resistance, the annular space between the tubular member and the outer layer which provides good inflow characteristics for produced fluid, and the expansion mechanism which obviates the need to mechanically expand the tubular member.
- one or more of the rings can be made of a material which swells upon contact with water produced from the earth formation.
- the rings can include a first set of rings susceptible of swelling in hydrocarbon fluid and a second set of rings susceptible of swelling in water, whereby the rings of the first and second sets are arranged in alternating order.
- any other suitable portion of the filter sheet can be connected to the rings.
- the filter sheets can be held in place by the shroud so that there is no need for connecting the filter sheets to some or al of the rings.
- any other suitable shroud can be used, for example a foldable shroud provided with hinges to allow unfolding of the shroud, or a shroud formed of a plurality of interconnected small tubulars whereby the individual tubulars become flattened upon expansion of the shroud.
