Definitions
- the present disclosure relates generally to wellbore operations and, more particularly, to a plug and abandonment system.
- Open hole plug and abandonment cement plugs require a reliable fundament to achieve successful separation of fluids.
- Conventional products may only separate the fluids and may not be able to hold any differential pressure that can occur due to losses and weight changes. For horizontal wells, the adequacy of conventional products is particularly questionable.
- FIG. 1 illustrates a plug and abandonment system, in accordance with certain embodiments of the present disclosure.
- FIGS. 2A and 2B respectively illustrate a plug of the plug and abandonment system in inactivated and activated states, in accordance with certain embodiments of the present disclosure.
- FIG. 3 illustrates the plug and abandonment system in an activated state, in accordance with certain embodiments of the present disclosure.
- FIG. 4 illustrates the plug and abandonment system at the cementing stage, in accordance with certain embodiments of the present disclosure.
- FIGS. 5A and 5B illustrate one exemplary disconnect tool, in accordance with certain embodiments of the present disclosure.
- the present disclosure relates generally to wellbore operations and, more particularly, to a plug and abandonment system.
- Embodiments of the present disclosure may be applicable to horizontal, vertical, deviated, or otherwise nonlinear wellbores in any type of subterranean formation. Embodiments may be applicable to injection wells as well as production wells, including hydrocarbon wells.
- Certain embodiments according to the present disclosure may provide a plug and abandonment system that may provide for plug placement, activation, and release.
- the plug and abandonment system may allow for fluid bypass and circulation in an inactivated state, and may be used to create a false well bottom in an activated state. Further, the plug and abandonment system may aid in setting balanced and competent cement plugs during remedial and primary cementing operations and may allow for successful first-attempt plug setting.
- FIG. 1 illustrates a plug and abandonment system 100 in accordance with certain embodiments of the present disclosure.
- the plug and abandonment system 100 includes a tubular member 105, which may include or be coupled to a workstring.
- the workstring may include a series of coupled tubular members (not shown) coupled in any conventional manner.
- adjacent tubular members may be threadedly connected at corresponding end portions.
- a continuous bore may be defined by the tubular members and the tubular member 105, and may extend for the length of the workstring.
- the plug and abandonment system 100 may be lowered into a borehole 120, which may be an open borehole or a cased borehole.
- the tubular member 105 may be coupled to a disconnect and activation tool 110.
- the tubular member 105 may comprise a drill pipe.
- a plug 115 may be coupled to the tubular member 105 via the disconnect and activation tool 110.
- the plug 115 may be lowered to any desired position within the borehole 120, including an off-bottom position.
- the borehole 120 may contain fluid disposed about the plug and abandonment system 100. As shown in Figure 1, with the plug 115 in an inactivated state and not sealing the borehole 120, an annulus 121 may be defined between the plug 115 and a surface of the borehole 120. In that inactivated state, the plug and abandonment system 100 may allow for fluid bypass and circulation.
- the plug 115 may be formed to have any suitable dimensions in the inactivated state to fit within various boreholes, depending on the implementation. However, once activated, the plug 115 may expand radially to fill the annulus 121. In particular, the plug 1 15 may be capable of being compressed longitudinally (i.e., generally along an axis of the plug 115) to change shape and expand radially until its outer surface substantially sealingly contacts the surface of the borehole 120. It should be recognized that the plug 115 may be made of different materials, shapes, and sizes.
- FIGS 2 A and 2B respectively show an exemplary plug 115 of the plug and abandonment system 100 in an inactivated state and in an activated state, in accordance with certain embodiments of the present disclosure.
- the plug 115 may include a tubular member 106, which may be a base pipe in certain embodiments.
- the plug 1 15 may include one or more layers 116.
- an inner layer 116A may surround or partially surround the tubular member 106.
- a sleeve 116B may surround or partially surround the inner layer 1 16 A. Once the plug 115 has been activated, the sleeve 116B may facilitate the maintenance of the one or more layers 116 in the compressed condition.
- An outer layer 116C may surround or partially surround the sleeve 116B.
- the inner layer 116A and outer layer 1 16C may include an elastomer material in certain embodiments.
- the sleeve 116B may include steel in certain embodiments.
- one or more of the inner layer 116A, sleeve 116B, and outer layer 116C may include any other suitable material that allows for a shape change of the plug 115 as disclosed herein.
- alternatives to the sleeve 116B e.g., a squirrel cage-like structure, or any other suitable structure
- the plug 115 may include a ring 119A disposed about the tubular member 106.
- a base 119B may be disposed generally opposite to the ring 119A, relative to the one or more layers 116, at a distal portion of the plug 115.
- the ring 119A may slidingly engage the tubular member 106 so that, with a suitable force applied to the ring 119A, the ring 119A may slide along the tubular member 106 and compress the one or more layers 116 against the base 119B so that the one or more layers 1 16 expand radially, as illustrated in Figure 2B.
- the ring 119A and the base 119B may include any suitable material and may have any suitable form that facilitates compression of the one or more layers 116 when a suitable force is applied to the ring 119A.
- Figure 3 illustrates the plug and abandonment system 100 in the activated state, in accordance with certain embodiments of the present disclosure.
- the shape change of the plug 115 accordingly may provide a hydraulic seal against the inner diameter of the borehole 120. In this manner, the plug 115 may be set on-demand.
- the plug 115 may be fabricated in any suitable manner so that it can be coupled to the disconnect and activation tool 110.
- the disconnect and activation tool 110 may include an activation feature 111.
- the activation feature 111 may include any suitable means for conveying a suitable force to compress the plug 1 15.
- the activation feature 111 may allow for a pressure inside the tubular 105 to be transferred, directly or indirectly, to compress the plug 115.
- the pressure may be transferred, directly or indirectly, to the ring 119A of the plug 115 in the non-limiting example illustrated in Figures 2 A and 2B.
- the activation feature 111 may include an activation ball or dart that may be dropped within the tubular member 105 to the activation tool 110.
- the activation feature 111 may be a surface-released, ball-operated or dart-operated, activation tool.
- a pressure inside the tubular 105 may be transferred, directly or indirectly, to the compress plug 115.
- the plug 115 may be disconnected from the tubular member 105.
- Figure 4 illustrates the plug and abandonment system 100 at a cementing stage with the plug 115 disconnected from the tubular member 105, in accordance with certain embodiments of the present disclosure.
- the tubular member 105 may be pulled a suitable distance away from the plug 115.
- Cement 130 may be conveyed via the tubular member 105 to a portion of the wellbore above the plug 115 after the separation of the tubular member 105 from the plug 115 has occurred.
- Centralizers (not shown) may be necessary to help hold the tubular member 105 tubing in place at this stage.
- the disconnect and activation tool 110 may be one of many types; the particular type may depend on well path, temperature, size, price, etc. Any suitable drop-off tool may be used.
- the disconnect and activation tool 110 may be a mechanically operated release device made of steel or composite, for example.
- the disconnect and activation tool 110 may be ball-operated or dart-operated. A ball or a dart may be dropped into the work string and displaced to the disconnect and activation tool 110. With suitable pressure applied from the behind to displace the ball or dart, the disconnect and activation tool 110 may be activated to disconnect the plug from the tubular 105.
- the disconnect and activation tool 110 may be connected to the plug 115 with a mechanical locking mechanism.
- the disconnect and activation tool 110 may be adapted to either be retrieved to the surface with the tubular member 105 or to remain with the plug 115 downhole.
- Certain non-limiting details of exemplary tool structure and operation are provided in U.S. Patent No. 6,772,835, which is hereby incorporated by reference in its entirety for all purposes.
- Figures 5A and 5B illustrate one disconnect and activation tool 110, in accordance with certain embodiments of the present disclosure.
- Figure 5 A shows the disconnect and activation tool 110 in the connected state; and
- Figure 5B shows the disconnect and activation tool 110 in the disconnected state.
- the disconnect and activation tool 110 comprises an upper body member 124 that may be coupled to the tubular member 105 and a lower body member 126 that may be coupled to the plug 115.
- the two body members are quick-releasably coupled together, and the upper member 124 defines a seat for receiving a flow prevention tool.
- the flow prevention tool may be a releasing dart or a ball.
- the flow prevention tool may be a ball valve as disclosed in U.S. Patent No. 7,472,752, which is hereby incorporated by reference in its entirety for all purposes.
- the seat has a greater diameter than the ball valve so as to allow the latter ball valve to pass through the disconnect 110.
- the plug 115 may include a swellable material.
- the swellable material may be able to close gaps that tend to form. For example, gaps may form over time due to formation changes that can occur due to faulting, depletion shrinkage, or stresses.
- the swellable material may expand to increase the sealing contact between the plug 115 and the borehole 120.
- the plug 115 generally should remain dormant until the activation agent is introduced to the swellable material.
- the term "swellable" is used herein to indicate an increase in volume of a material. Typically, this increase in volume is due to incorporation of molecular components of a fluid into the swellable material itself, but other swelling mechanisms or techniques may be used, if desired.
- the swellable material may swell when contacted by an activating agent, such as an inorganic or organic fluid.
- a swellable material may be a material that swells upon contact with and/or absorption of a hydrocarbon, such as oil.
- a swellable material may be a material that swells upon contact with and/or absorption of an aqueous fluid.
- Suitable swellable materials include, but are not limited, to those disclosed in U.S. Patent Nos. 3,385,367; 7,059,415; and 7,143,832; the entire disclosures of which are incorporated by reference.
- Some exemplary swellable materials may include, but are not limited to, elastic polymers, such as EPDM rubber, styrene butadiene, natural rubber, ethylene propylene monomer rubber, ethylene-propylene-copolymer rubber, ethylene propylene diene monomer rubber, ethylene-propylene-diene terpolymer rubber, ethylene vinyl acetate rubber, hydrogenized acrylonitrile butadiene rubber, acrylonitrile butadiene rubber, isoprene rubber, butyl rubber, halogenated butyl rubber, brominated butyl rubber, chlorinated butyl rubber, chlorinated polyethylene, chloroprene rubber and polynorbornene.
- elastic polymers such as EPDM rubber, styrene butadiene, natural rubber, ethylene propylene monomer rubber, ethylene-propylene-copolymer rubber, ethylene propylene diene monomer rubber, ethylene-propylene-diene terpolymer rubber
- the rubber of the swellable material may also have other materials dissolved in or in mechanical mixture therewith, such as fibers of cellulose. Additional options may be rubber in mechanical mixture with polyvinyl chloride, methyl methacrylate, acrylonitrile, ethylacetate or other polymers that expand in contact with oil. Other swellable materials that behave in a similar fashion with respect to hydrocarbon fluids or aqueous fluids also may be suitable. Those of ordinary skill in the art, with the benefit of this disclosure, will be able to select an appropriate swellable material for use in the present invention based on a variety of factors, including the desired swelling characteristics of the swellable material and the environmental conditions in which it is to be deployed.
- Delay systems may be used to delay the swelling activation in certain embodiments.
- swellable material elements may be encapsulated so that they generally do not swell until after a delay period after exposure to hydrocarbon and/or water. The hydrocarbon is absorbed into the swellable material such that the volume of the swellable material increases creating an expansion of the swellable material.
- certain embodiments according to the present disclosure may enable the placement of a competent plug downhole.
- certain embodiments may ensure well integrity and may provide reliable plug and abandonment in open hole and cased hole implementations.
- Certain embodiments may provide zonal isolation on demand, being able to hold differential pressure and avoid losses to the formation.
- Certain embodiments may ensure isolation of water breakthrough because of production from nearby wells.
- Certain embodiments also may have the swellable feature of closing gaps that may tend to form over time due to formation changes.
- Certain embodiments may avoid the problems of conventional plugging approaches that are vulnerable to contamination and disturbance during initial setting. With certain embodiments, there is no need for a separate physical barrier between a cement plug and the fluid below the plug, as is needed in conventional operations to prevent the introduction of cement slurry into in the fluid.
