Definitions
- the field of the invention is methods for plugging and abandoning wells and more particularly methods that allow multiple operations in a single trip including among other steps running and setting a bridge plug, perforation, washing the perforations, delivering cement under pressure into the perforations and pulling the bottom hole assembly from the location without swabbing the well.
- a bottom hole assembly enables a one trip procedure to set a bridge plug and release from that bridge plug with the BHA.
- a perforating gun is fired and a straddle tool above the gun in repositioned to wash the perforations as the opposed packer cups are moved along the perforations.
- a dropped ball closes a circulation port above the upper packer cups and the ball seat is blown out.
- a disconnect releases the lower part of the straddle tool with the lower packer cups that are uphole oriented.
- Cement can now be delivered past the upper packer cups and pressurized to squeeze the cement into the perforations using the upper cups to hold the pressure.
- Another ported sub above the upper cups has a port opened to prevent swabbing as the BHA is removed.
- the invention is a drill pipe string (1 l)-borne borehole assembly (10) comprising a washing tool assembly (18) , comprising:
- the invention is also a method for plugging a cased petroleum well comprising the steps of: a) assembling on a drill pipe string (11) a borehole assembly (BHA) (10) comprising
- FIG. 1 is the run in position of the BHA of the invention
- FIG. 2 is the BHA of FIG. 1 in the position having set the plug, released the plug, perforated, washed behind casing and circulated out debris, split the wash tool and started conducting delivery of cement.
- Fig. 3 illustrates a section of the BHA of the invention.
- the BHA 10 has a bridge plug 12 and an associated setting device 14 located above.
- the setting device 14 is preferably pressure operated against a seated ball (not shown) but other types of devices can be used without departing from the invention.
- a perforating gun 16 is mounted above the actuator followed by a wash tool assembly 18 that preferably has a lower ported sub 20 with ports 22 a pair of lower packer cups 24 and 26 followed by a ported body 28 with fluid outlets 30 for washing the perforations as will be explained below.
- a disconnect 32 is located immediately below the upper cups 34 and 36 which are both looking downhole. Cups 24 and 26 are looking uphole.
- Upper ported sub 38 has port openings 40 There is a flow passage 42 that runs between ports 22 and 40. Ports 40 can be selectively closed with an internal sliding sleeve associated with a ball seat that can shift the sleeve before the ball seal gets blown out for the purposes of delivering the cement or other sealing material as will be explained below.
- This internal assembly is not shown but it is of a type well known in the art.
- another ported sub 44 that has a selectively opened port or ports 46 to allow circulating out of excess cement and to prevent well swabbing when pulling out of the hole by allowing fluid to bypass cups 34 and 36 on the trip out of the hole with the BHA 10 through now opened ports 46.
- the one trip method works by virtue of running in the BHA 10 into a cased (11) hole, for example.
- the bridge plug 12 and its plug actuator 14 are placed far enough below the perforations to be made by the gun 16 so that when the gun 16 later is dropped, the gun 16 will be far enough below the perforations formed so as to not interfere with the step of washing through the perforations that comes later.
- the bridge plug 12 which is of a type known in the art, is properly positioned the plug actuator 14 is energized, preferably with pressure, and the actuation of the plug also causes preferably a second disconnector (13) to release the actuator 14 from the gun 16 so that the BHA 10 can be repositioned to properly position the perforating gun 16 to one or more positions for conducting the perforation.
- the wash tool assembly is then positioned either near the top or near the bottom of the section of the casing wherin perforations have just been made by the gun 16, and the fluid from the surface is pumped through ports 30 that are between cups 26 and 34 such that pressure driven fluid at high velocity can be flushed out through the perforations to clean them and the annulus by removing debris from them with the fluid going into the perforations and coming out in the casing main bore either below cup 24 or above cup 36.
- the fluid that comes out below cup 24 may then enter ports 22 and pass up through passage 42 on the way to communicating with ports 40 that are above cup 36.
- main bore passage (51) ends at ports 30 that before disconnection at disconnector (32) allows surface pumping to reach ports 30 for the washing procedure that preferably takes place as the BHA 10 moving axially in the borehole along the perforations.
- direction of the washing tool assembly (18) can be top down or bottom up or any other pattern as long as the entire span of perforations gets exposed to the fluid jet stream that comes out of the ports 30.
- the next big step is to pump cement or some other seal material.
- the ports 40 need to be closed and a large passage (54) needs to be opened for the pumped cement at a location where the pumped cement can be pressurized into the perforations after delivery.
- the internal sleeve in sub 40 that is shifted by a ball landing on a seat where the seat gets blown out after shifting is actuated with pressure on the seated ball.
- the ports 40 are then closed and the passage for the cement is back to full bore (51) as the ball and seat have been blown out.
- FIG. 2 shows the disconnector (32) apart so that the guns 16 and lower cups 24 and 26 as well as the body of the tool 18 with the lower part of the disconnector 32 are dropped downhole onto the plug actuator 14.
- the ports 40 are closed with the shifting of the internal sleeve and the blowing out of the ball seat with the ball, shown schematically in FIG. 2 as 48.
- the cement or other sealing material represented by arrow 50 can be pumped out through full-bore aperture (54) and the cement will be forced into the perforations 52.
- the lower cups 24 and 26, although earlier dropped still can act to stop the cement that falls down to fill the borehole. Alternatively the cement can go down to the bridge plug 12.
- the cups 34 or 36 can offer cement retention to pressures of about 5000 PSI to aid in forcing the cement represented by arrow 50 into the perforations.
- the closing of ports 40 forces the pressurized cement below the cups 34 and 36.
- the next step is to open ports 46 on pump out sub 44 so that excess cement can be circulated out.
- the opening of ports 46 also prevents well swabbing as flow from above cup 36 can get out below cup 34 through open end 52.
- the cement in the borehole can be drilled out in a separate trip and a cement bond log can be run to determine the integrity of the cement in the perforations 52.
- the tool 18 is moved as the cement is pumped out through the full-bore aperture (54) to push the cement into the entire interval.
- the bridge plug 12 is set far enough below the perforation so that when the disconnect 32 separates that portion of the BHA 10 that drops is still laying well below the perforations 52 so as to not interfere with subsequent cementing or later production from those perforations if they are to be reopened for any reason.
- the upper cups 34 and 36 still function as a pressure retainer as does lower cup 26 backed up with cup 24.
- the tool 18 is unique in that it serves multiple function of jetting the perforations clean through ports 30 at high fluid velocities but is then reconfigured by coming apart at the disconnect (32) between opposed cups in such a way as to open the aperture (54) with a bigger flow channel (51) for the cement to shorten the cementing time and the pumping power required to deliver the cement.
- This tool 18 also has a bypass from above cup 36 at ports 40 through to below cup 24 at ports 22. This bypass is independent of the passage that directs wash fluid to ports 30 when tool 18 is intact and allows large bore flow of cement out lower end aperture (54) after the disconnect 32 is operated.
- packer cups are discussed as the seals other types of seals are envisioned such as inflatable or mechanically or hydraulically set resettable packers, for example.
- An advantage of the packer cups is that even when released they have a possibility to hold cement pressure and even if the lower cups 24 and 26 do not hold there is still the bridge plug (12) as a backup.
- the tool 18 in the background art is illustrated in a plug and abandon method, the tool 18 has a new application wherein different flow regimes are needed for different functions at different times while saving a trip out of the hole to accomplish both functions.
- a part of the well is isolated with a packer or bridge plug (12).
- the perforations are formed and then cleaned with a wash tool (18) that flushes fluid out through the perforations between spaced barriers, the lower and upper swab cups (24, 26, 34, 36) as the assembly (18) is moved to allow washing through all the perforations in a desired direction while providing a bypass path around the spaced isolators for return fluid to the surface around the tool interval between the spaced seals.
- the bypass (42) upper port (40) is then closed and the washing tool assembly (18) is split at the disconnector (32) between the seals to open a large flow passage (54) for the subsequent pumping out of cement with any potential bypass paths (40) around the top seals that remain with the BHA closed off.
- the cement is squeezed out and through the perforations using the upper seals (34, 36) still with the BHA to retain pressure up to about 5000 PSI to ensure good cement penetration into the perforations.
- the lower seals even though dropped by the time cement is pumped, may still hold pressure but if they don't, the bridge plug is there for that purpose.
- the pump out sub is then activated and after picking up the excess cement can be circulated out and swabbing of the well is prevented because the open port on top of the upper seal can be a bypass through the upper packer cups because the path is open to lower end 54.
