Definitions

  • Horizontal wells that require sand control are typically open hole completions.
  • stand-alone sand screens have been used predominately in these horizontal open holes.
  • operators have also been using gravel packing in these horizontal open holes to deal with sand control issues.
  • the gravel is a specially sized particulate material, such as graded sand or proppant, which is packed around the sand screen in the annulus of the borehole.
  • the gravel acts as a filter to keep any fines and sand of the formation from migrating with produced fluids.
  • a prior art gravel pack assembly 20 illustrated in Figure 1A extends from a packer 14 downhole from casing 12 in a borehole 10, which is a horizontal open hole.
  • a packer 14 downhole from casing 12 in a borehole 10, which is a horizontal open hole.
  • operators attempt to fill the annulus between the assembly 20 and the borehole 10 with gravel (particulate material) by pumping slurry of fluid and gravel into the borehole 10 to pack the annulus.
  • For the horizontal open borehole 10 operators can use an alpha-beta wave (or water packing) technique to pack the annulus.
  • This technique uses a low-viscosity fluid, such as completion brine, to carry the gravel.
  • the assembly 20 in Figure 1A represents such an alpha-beta type.
  • a wash pipe 40 into a screen 25 and pump the slurry of fluid and gravel down an inner work string 45.
  • the slurry passes through a port 32 in a crossover tool 30 and into the annulus between the screen 25 and the borehole 10.
  • the crossover tool 30 positions immediately downhole from the gravel pack packer 14 and uphole from the screen 25.
  • the crossover port 32 diverts the flow of the slurry from the inner work string 45 to the annulus downhole from the packer 14.
  • another crossover port 34 diverts the flow of returns from the wash pipe 40 to the casing's annulus uphole from the packer 14.
  • the slurry moves out the crossover port 32 and into the annulus.
  • the carrying fluid in the slurry then leaks off through the formation and/or through the screen 25.
  • the screen 25 prevents the gravel in the slurry from flowing into the screen 25.
  • the fluids passing alone through the screen 25 can then return through the crossover port 34 and into the annulus above the packer 14.
  • the gravel drops out of the slurry and first packs along the low side of the borehole's annulus.
  • the gravel collects in stages 16a, 16b, etc., which progress from the heel to the toe in what is termed an alpha wave. Because the borehole 10 is horizontal, gravitational forces dominate the formation of the alpha wave, and the gravel settles along the low side at an equilibrium height along the screen 25.
  • the gravel pack operation When the alpha wave of the gravel pack operation is done, the gravel then begins to collect in stages (not shown) of a beta wave. This forms along the upper side of the screen 25 starting from the toe and progressing to the heel of the screen 25. Again, the fluid carrying the gravel can pass through the screen 25 and up the wash pipe 40. To complete the beta wave, the gravel pack operation must have enough fluid velocity to maintain turbulent flow and move the gravel along the topside of the annulus. To recirculate after this point, operators have to mechanically reconfigure the crossover tool 30 to be able to washdown the pipe 40.
  • FIG. 1B shows an example assembly 20 having shunts 50 and 52 (only two of which are shown).
  • the shunts 50/52 for transport and packing are attached eccentrically to the screen 25.
  • the transport shunts 50 feed the packing shunts 52 with slurry, and the slurry exits from nozzles 54 on the packing shunts 52.
  • the gravel packing operation can avoid areas of high leak off in the borehole 10 that would tend to cause bridges to form and impair the gravel packing.
  • Prior art gravel pack assemblies 20 for both techniques of Figures 1A-1B have a number of challenges and difficulties.
  • the crossover ports 32/34 may have to be re-configured several times.
  • the slurry pumped at high pressure and flow rate can sometimes dehydrate within the assembly's crossover tool 30 and associated sliding sleeve (not shown). If severe, settled sand or dehydrated slurry can stick to service tools and can even junk the well.
  • the crossover tool 30 is subject to erosion during frac and gravel pack operations, and the crossover tool 30 can stick in the packer 14, which can create extremely difficult fishing jobs.
  • US 2003/089495 A1 discloses a sand screen comprising a base pipe with openings cut directly thereon.
  • the size, shape, and configuration of the openings may be varied depending on the filtration, inflow, and strength characteristics desired by the operator.
  • the openings may be cut directly on the base pipe by use of water jet, laser, or saw cutting techniques.
  • US 3134439 A relates to gravel packing a liner in the borehole of a well and more particularly to a method and apparatus utilizing a single trip into a well for washing a liner into the borehole of the well to the desired depth and packing the gravel in the space surrounding the liner.
  • US 2008/283252 A1 discloses a technique for treating a plurality of well zones with a service tool during a single trip downhole.
  • the service tool is run downhole to a selected well zone that is isolated for treatment. Following treatment of the well zone, the service tool is moved to a subsequent well zone isolated for treatment.
  • the active length of the service tool can be adjusted to correspond with the well zone length to optimize the well treatment operation.
  • US 2009/095471 A1 discloses an apparatus having a first outer tubular member and a first inner tubular member having a first space therebetween.
  • the first inner tubular member can have a first internal bore.
  • the apparatus can further include a second outer tubular member and a second inner tubular member having a second space therebetween.
  • the second inner tubular member can have a second internal bore.
  • a first coupling flowpath can be positioned between the first and second spaces.
  • a second coupling flowpath can be positioned between the first and second internal bores.
  • a selectively closeable flowpath can be positioned between the first coupling flowpath and the second coupling flowpath.
  • US 2009/025923 A1 discloses a technique that is usable with a well.
  • the technique includes running a screen assembly and a service tool as a unit into a well and using the service tool in connection with a sand control operation.
  • the use of the service tool in connection with the sand control operation includes operating at least one valve of the screen assembly.
  • the technique includes withdrawing the service tool from the well after the sand control operation and running a completion into the well to operate the valve(s) of the screen after the withdrawal.
  • the subject matter of the present disclosure is directed to overcoming, or at least reducing the effects of, one or more of the problems set forth above.
  • An excess slurry disposal apparatus and method of a gravel pack operation disposes of excess slurry from an inner string into the annulus around a gravel pack assembly.
  • the apparatus has a body with a body passage communicating from a heel to a toe, and part of the body towards the toe can have a shoe track with a float shoe.
  • the body can be any part of the gravel pack assembly disposed at some point in the borehole and does not necessarily need to be disposed at the shoe track. Nevertheless, reference may be made to the body being at or part of a shoe track for convenience.
  • a closure is disposed on the shoe track and can control or selectively open and close fluid communication through the flow ports.
  • the closure can be a check valve, a sliding sleeve, a rotating sleeve, a rupture disk, a screen, etc.
  • a sliding sleeve for example, the closure can be moved by a shifting tool on the inner string to open or close fluid communication through the flow ports. Movement of the sleeve can also open and close fluid communication through the bypass. Alternatively, the bypass can always remain open and allow for fluid flow therethrough.
  • the screen prevents at least some particulates in the fluid returns from passing into the shoe track so the gravel will fill the borehole annulus around the shoe track.
  • the fluid returns bypass uphole of the sealed outlet ports and flow ports by going uphole through the bypass around the flow ports. At this point, the fluid returns can pass uphole in the gravel pack assembly.
  • the shoe track can have a float shoe at the track's toe.
  • the inner string can be moved to a selective position in the shoe track to seal one of its seals on one of the shoe track's seats. This isolates the tool's outlet portions to the float shoe so washdown fluid can be pumped out of the shoe track and around the borehole annulus.
  • the apparatus having the shoe track can include other components for gravel pack operations.
  • parts of the apparatus uphole of the shoe track can have additional flow ports, seats, and screens.
  • the inner string can be moved to selective positions in the apparatus to seal the string's outlet ports with these other flow ports, and the inner string can communicate slurry from the outlet ports to the borehole annulus.
  • the flow of slurry at these other flow ports can be used to gravel or frac pack the borehole around different portions of the apparatus in a toe-to-heel gravel packing operation. Some of these different portions of the apparatus can also be isolated from one another with packers or the like.
  • Figure 2 shows a gravel pack assembly 100 having a liner 170 extending from a liner hanger 14 and having several gravel pack sections 102A-C separated by isolating elements 104.
  • the assembly 100 segments several compartmentalized reservoir zones so that multiple gravel or frac pack operations can be performed separately in each zone.
  • the isolating elements 104 and gravel pack sections 102A-C are deployed into the well in a single trip.
  • the isolating elements 104 referred to herein as packers for convenience, can have one packer or a combination of packers to isolate the gravel pack sections 102A-C from one another.
  • Any suitable packers can be used and can include hydraulic or hydrostatic packers 106 and swellable packers 107, for example, used alone or in combination with one another as shown.
  • Each gravel pack section 102A-C can be similar to the gravel pack assemblies disclosed in incorporated U.S. Pat. Appl. No. 12/913,981 .
  • each gravel pack section 102A-C has two screens 140A-B, alternate path devices or shunts 150, and housings 130A-B with flow ports 132A-B, although any of the other disclosed variations can be used.
  • each section 102A-C can have other components disclosed in incorporated U.S. Pat. Appl. No. 12/913,981 .
  • the inner string 110 can again be moved so that the outlet ports 112 isolates to upper flow ports 132B connected to the shunts 150. Slurry pumped down the inner string 110 can then fill the annulus around the lower end of the first gravel pack section 102A. Operations can then proceed with similar steps being repeated up the hole for each of the gravel pack sections 102B-C separated by the packers 104.
  • FIGS. 3A-3B portions of the assembly 100 are shown set up for a washdown operation.
  • the service tool 18 sits on the liner hanger 14 in the casing 12, and seals 16 on the service tool 18 do not seal in the liner hanger 14 so hydrostatic pressure can be transmitted past the seals 16.
  • the distal end of the inner string 110 fits through the screen sections 140A-B of the lower section 102A, and one of the string's seals 114 seals against a seat 124 near a float shoe 122 on the assembly's shoe track 120.
  • a bypass 200A Downhole, a bypass 200A is disposed near the float shoe 122 and can allow circulated fluid to pass to the borehole annulus during this process.
  • the bypass assembly 200A can be a check valve, a screen portion, a movable sleeve, or other suitable device that allows flow of returns and not gravel from the borehole annulus to enter the assembly 100.
  • the bypass assembly 200A as a screen portion can have any desirable length along the shoe track 120 depending on the implementation.
  • the bypass 200A (if a screen or the like) can allow the circulated fluid to flow out of the shoe track 120 and into the borehole annulus, as circulated fluid is also allowed to pass out of the float shoe 122. If the bypass 200A uses a check valve that allows fluid returns into the shoe track 120, fluid flow out of the bypass 200A can be restricted during washdown. If the bypass 200A uses a movable sleeve, fluid flow in and out of the bypass 200A can be restricted during washdown by having the sleeve closed, which can be done with a suitable shifter on the inner string 110, for example.
  • gravel packing can then be performed by moving the inner string 110 to the flow ports 132A to gravel pack the borehole annulus from toe-to-heel. After gravel packing at this first position, the inner string 110 can then be moved to the next flow ports 132B to further gravel pack the annulus around the shoe track and/or to dispose of excess slurry from the inner string 110.
  • operators can evacuate excess slurry from the inner string 110 during gravel packing operations.
  • the exterior space outside the shoe track 120 provides a volumetric space for disposing of any excess gravel remaining in the inner string 110 after gravel packing one or more sections 102A-B. Operators may also intentionally gravel pack around the shoe track 120 as opposed to using it for disposing of excess slurry.
  • the shoe track 120 has the float shoe 122 that allows fluid flow out of the shoe track 120 and prevents flow into the shoe track 120, a path for return fluids is needed when slurry is pumped into the borehole annulus around the shoe track 120 to dispose of the excess slurry from the inner string 110.
  • Figures 4A-4B show portions of the assembly 100 set up for sand disposal.
  • operators deploy the inner string 110 to the second flow ports 132B on the gravel pack section 102A having the shoe track 120. This can be done after operators have reached sandout while pumping slurry at the section's first flow ports 132A in the first ported housing 130A or after gravel packing has been performed on other gravel pack sections (e.g., sections 102B-C on the assembly 100 of Figure 2 ). In any event, operators perform a sand disposal operation to clear the inner string 110 of excess slurry or to intentionally gravel pack around the shoe track 120.
  • this second stage of pumping slurry may be used to further gravel pack the borehole 10.
  • pumping the slurry through the shunts 150 enables operators to evacuate excess slurry from the string 110 to the borehole annulus around the shoe track 120 without reversing flow in the string from the main flow direction (i.e., toward the string's ports 112). This is in contrast to the typical practice of reversing the direction of flow by pumping fluid down an annulus to evacuate excess slurry from a string.
  • the shunts 150 attached to the ported housing 130B above the lower screen section 140A can be used to dispose of excess gravel from the inner string 110 around the shoe track 120 (and optionally inside the shoe track 120 itself).
  • the slurry travels from the outlet ports 112, through flow ports 132B, and through the shunts 150. From the shunts 150, the slurry then passes out side ports or nozzles 154 in the shunts 150 and fills the annulus around shoe track 120. This provides the gravel packing operation with an alternate path different from the assembly's primary path of toe-to-heel packing of the annulus with gravel.
  • the shunts 150 carry the slurry down the lower screen section 140A so a wash pipe does not need to be disposed in the shoe track 120.
  • the bypass assembly 200A disposed in the assembly 100 near the float shoe 122 allows fluid during this process to enter the assembly 100.
  • the bypass assembly 200A can be a check valve, a screen portion, a sleeve, or other suitable device that allows the flow of fluid returns and not gravel from the borehole to enter the assembly 100.
  • the bypass assembly 200A can have any desirable length along the shoe track 120 depending on the implementation so that the depicted size of the bypass assembly 200A is merely meant to be a representation.
  • operations may reach a "sand out" condition or a pressure increase while pumping slurry at the flow ports 132B.
  • a valve, rupture disc, or other closure device 156 in the shunts 150 can open so the gravel in the slurry can then fill inside the shoe track 120 after evacuating excess gravel around the shoe track 120. In this way, operators can evacuate more excess gravel inside the shoe track 120. As this occurs, fluid returns can pass out the lower screen section 140A, through the packed gravel, and back through upper screen section 140B to travel uphole.
  • the lower ported housing 130A or other portions of the gravel pack assembly 100 can have a bypass, another shunt, or the like, which can be used to deliver fluid returns past the seals 114 and seats 134 and uphole. Details of other bypass assemblies according to the present disclosure are discussed later.
  • FIG. 5 shows another gravel pack assembly 100 having a liner 170 extending from a liner hanger 14 and having several gravel pack sections 102A-C separated by packers 104 disposed in a borehole 10.
  • this gravel pack assembly 100 can be similar to that discussed previously and to those disclosed in incorporated U.S. Pat. Appl. No. 12/913,981 .
  • the bypass assembly 200B has flow ports 210, a screen 220, and a bypass channel 230.
  • the flow ports 210 communicate with the borehole annulus.
  • internal seats 214 are disposed uphole and downhole of the flow ports 210 for engaging seals of the inner string as discussed below.
  • a reverse arrangement could also be used in which internal seals disposed uphole and downhole of the flow ports 210 can engages seats of the inner string.
