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. When applied, the gravel acts as a filter to keep any fines and sand of the formation from migrating with produced fluids.
  • the service tool for a gravel pack assembly is typically moved to perform various functions during gravel pack operations. Due to well depth, deviation, tubing stretch, friction, and the type of gravel pack completion to be run, determining the position of the service tool downhole in the assembly can be very difficult. This is especially true in long horizontal gravel pack completions. In the end, pumping of sand slurry when the tool is in an incorrect position in the assembly can cause the service tool to stick and can have catastrophic consequences.
  • US2007227731 (A1 ) discloses a technique to facilitate gravel packing in a well.
  • a conduit surrounded by a screen is deployed in an isolated lower wellbore region.
  • the conduit cooperates with one or more valves that can be selectively opened to relieve wellbore pressure resulting from advancement of the beta wave during the gravel packing procedure.
  • a control system enables dependable and timely opening of the one or more valves to relieve wellbore pressure and protect the surrounding formation.
  • 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.
  • a method of hydraulically locating an inner string in a downhole assembly is described according to the appended claims.
  • a downhole apparatus is also described according to the appended claims.
  • an adjustment device is used to adjust a length of an inner string deployed in a downhole assembly, such as a toe-to-heel gravel pack assembly.
  • the device has first and second (tubular) members telescopically coupled together.
  • the first member is coupled to one portion of the inner string, while the second member is coupled to another portion of the inner string.
  • a ratchet disposed on the first member can engage a catch on the second member to fix the length of the adjustment device.
  • the ratchet can include a dog having a plurality of chamfered teeth.
  • the catch which is movable relative to the ratchet, can include a plurality of grooves defined around the outside of the second member to engage the teeth of the ratchet dog.
  • the inner string and device are deployed in the downhole assembly to determine proper space out of the inner string for subsequent operation, such as gravel packing.
  • the first and second members of the device are in an extended condition.
  • the ratchet allows the second member to move in one direction relative to the first member so the device can collapse and shorten the length of the inner string.
  • a key between the two members can ride in a slot, which allows the two members to slide relative to one another but not rotate.
  • the ratchet engages the catch (i.e., the teeth on the dog engages in the grooves) to prevent the second member from moving in an opposite direction relative to the first member. In this way, the device does not extend again as the inner string is pulled uphole so the device is maintained in one fixed length.
  • operators can permanently maintain the adjustment device in its fixed length determined downhole by installing a locking element between first and second telescoping members.
  • operators can replace the ratchet dogs with chamfered teeth with locking dogs having unchamfered teeth. Engaged in the grooves of the catch, the locking dog will prevent movement of the second member in either direction inside the first member.
  • a downhole assembly such as a gravel pack assembly
  • a body passage therethrough.
  • First sealing surfaces or seats disposed in the body passage separate a sealable space in the body passage.
  • these seats can be polished surfaces in the body passage having a smaller diameter than the rest of the passage.
  • An inner string such as an inner string of a gravel pack assembly, is movably disposed in the body passage and defines a bore for communicating fluid from a surface pump to an outlet port on the inner string.
  • a valve in the bore can divert the pumped fluid out the outlet port.
  • First seals disposed on the inner string selectively seal with the first seats when the inner string is moved in the body.
  • the outlet port communicates the pumped fluid into the sealable space of the body, which produces a measureable pressure buildup.
  • a first position of the inner string can then be correlated to the known location of the sealable space in the downhole assembly.
  • a second position for the inner string in the body can then be calculated based on a known distance in the downhole assembly from the first location to a second location of another feature, such as a port in the assembly.
  • Being able to determine positions for the inner string allows operators to more properly position the inner string to desired locations in the downhole assembly during gravel pack or other operations.
  • Figure 1 shows a downhole assembly 100 having an adjustment device 30 and a locating device 160 according to the present disclosure.
  • the downhole assembly 100 is a gravel pack assembly, although other type of assemblies used downhole can benefit from the disclosed devices 30 and 160.
  • a cementing assembly for cementing a liner in an open borehole may benefit from the disclosed devices 30 and 160.
  • other suitable downhole assemblies for one or both of the devices 30 and 160 will be apparent to one of ordinary skill in the art.
  • the gravel pack assembly 100 has multiple gravel pack sections 102A-B, but the assembly 100 can generally have one or more sections. With multiple sections 102A-B, however, the assembly 100 segments compartmentalized reservoir zones so that multiple gravel pack and frac pack operations can be performed in the borehole 10. Isolating elements 104, such as packers, can dispose between these gravel pack sections 102A-B to isolate them from one another.
  • the gravel pack assembly 100 can be similar to the gravel pack assemblies disclosed in incorporated U.S. Appl. Ser. No. 12/913,981 .
  • the gravel pack assembly 100 is a toe-to-heel gravel pack system that allows operators to pack the borehole 10 from the toe to heel in each section 102A-B.
  • each gravel pack section 102A-B has two screens 140A-B, alternate path devices or shunts 150, and ported housings 130A-B with ports 132A-B, although any of the other disclosed variations can be used.
  • gravel pack operations with the assembly 100 involve initially deploying an inner string 110 into the first gravel pack section 102A.
  • a conveyance 20 manipulates the inner string 110 and can use any of the conveyance methods known in the art.
  • a pumping system 22 can pump fluid and/or slurry for a gravel or frac pack operation down the inner string 110 as needed, and a pressure sensor 24 can detect a buildup of pressure caused by the pumped fluid.
  • Many of these features are conventional components and are not described in detail here.
  • the uphole packer 14 on a liner hanger and other packers 104 along the assembly 100 remain unset. Operators pump washdown fluid through the inner string 110, and the circulated fluid leaves the string's outlet ports 112 and passes through a float shoe 122 of a shoe track 120 at the end of the first section 102A. In washing down the borehole 10, the circulated fluid passes through the annulus and uphole so the fluid can enter the casing 12 and return to the surface.
  • the assembly 100 can commence with gravel pack operations.
  • the string's outlet ports 112 with its seals 114 isolate in fluid communication with the lower flow ports 132A in the first housing 130A of the first section 102A.
  • Positioning the string's ports 112 with the flow ports 132A requires operators to calculate distances and determine the string's position in the assembly 100 relative to the ports' locations.
  • the assembly 100 uses a hydraulic locating device 160 as discussed in detail below. As shown, the device 160 is preferably located between the shoe track 120 and the ported housing 130A.
  • the inner string 110 can again be moved so that the outlet ports 112 isolate to upper flow ports 132B connected to the shunts 150 in this first section 102A. Slurry pumped down the inner string 110 can then fill the borehole annulus around the lower end of the shoe track 120, which can be done to further pack the borehole 10 or to dispose of excess slurry from the string 110.
  • the inner string 110 in this toe-to-heel assembly 100 first locates at the bottom of the shoe track 120 to communicate washdown fluid out the float shoe 122 as described above.
  • the gravel pack operation then proceeds with the inner string 110 being moved to a number of flow ports 132 along the assembly 100. If the inner string 110 is not run or spaced out properly, then operations will not proceed effecting, and the assembly 100 may become damaged.
  • the adjustment device 30 has an upper member 40 with a distal member 60 telescopically disposed therein.
  • the distal member 60 is linearly expandable and collapsible relative to the upper member 40.
  • Figure 2 shows the adjustment device 30 in more detail.
  • the device 30 includes an upper (tubular) member 40 and a distal (tubular) member 60 telescopically disposed therein.
  • the device 30 is shown with two telescoping members 40 and 60, more members could be used.
  • the upper member 40 has a coupling 42 that couples to uphole components (not shown), such as an uphole portion of the inner string (110).
  • the distal member 60 extends from the upper member's downhole end, and the two members 40 and 60 may be initially held in an extended condition by shear pins 46 or the like.
  • Ratchet dogs 50 are disposed in slots 45 around the outside of the upper member 40, and a retaining sleeve 44 disposed on the upper member 40 helps hold the ratchet dogs 50 in place. Seals 62 on the distal member 60 engage inside the upper member 40 to inhibit fluid flow between the members 40 and 60.
  • the outside of the distal member 60 has catches or grooves 65 spaced apart from one another along most of the member's length.
  • the actual length of the members 40 and 60 can be much greater than depicted in Figure 2 so that the distal member 60 can expand and collapse a considerable distance as need for an implementation.
  • the device 30 is shown extended as when it is initially run downhole.
  • the ratchet dogs 50 engage in the topmost catch grooves 65 on the distal member 60.
  • the members 40 and 60 collapses, and the ratchet dogs 50 ratchet up the catch grooves 65 on the distal member 60.
  • Figure 3 shows a detail of the ratchet dogs 50 engaging in catch grooves 65 on the distal member 60.
  • the ratchet dogs 50 have a number of teeth 55 with chamfered leading edges. As the distal member 60 moves into the upper member 40, the chamfered teeth 55 let the catch grooves 65 pass thereby.
  • the springs 52 can be leaf springs or other types of biasing elements.
  • the catch grooves 65 are arranged in sets to engage the multiple teeth 55 on the ratchet dogs 50, but it will be appreciated that a number of ratcheting mechanisms can be used, including those conventionally used in downhole tools for packers or sliding sleeves.
  • the assemblies 40 and 60 collapse together until the upper member 40 (or some other part of the inner string 110) shoulders out in the assembly 100. Shouldering can be achieved in a number of ways.
  • the assembly 100 can have a restricted passage that allows the distal member 60 to pass therethrough when bottoming out in the assembly 100, but the restricted passage engages the upper member 40 when moved against it.
  • Figures 4A-4B show different cross-sections of the adjustment device 30 in a fully collapsed position.
  • Figure 4A shows the ratchet dogs 50 disposed in the upper member 40 for engaging the outer catch grooves 65 in the distal member 60.
  • the dogs 50 are preferably arranged consistently about the circumference of the members 40 and 60, although they need not be at the same longitudinal location.
  • Figure 4B shows a key 70 disposed in the upper member 40 and held by the sleeve 44.
  • the key 70 rides within a longitudinal groove 67 along a length of the distal member 60.
  • the two members 40 and 60 can slide relative to one another, but the key 70 prevents rotation of the members 40 and 60 relative to one another.
  • one key 70 is shown, more than one key 70 may be used.
  • the inner string 110 runs to the very bottom of the assembly 100 to the shoe track 120 for washdown during gravel pack operations. Then, the inner string 110 is manipulated in the assembly 100 to a number of ports 132A-132B and other positions to perform the gravel pack operations in the various sections 102A-B. As will be appreciated, knowing the location (distance) of various features (ports, etc.) relative to the position of the inner string 110 in the assembly 100 can help operators move and position the inner string 110 properly and effectively in the assembly 100 during operations.
  • the gravel pack assembly 100 includes one or more locating device 160 disposed thereon for locating the inner string 110 at different positions in the assembly 100.
  • one of the locating devices 160 can be disposed near the shoe track 120 between the float shoe 122 and the first ports 132A on the ported housing 130A of the first section 102A. Having the device 160 in this location allows operators to correlate the inner string's position to at least one location in the assembly 100, and preferably the furthest location.
  • the length of the assembly 100, the length of the inner string 110 to reach the assembly's end, drag forces, friction, possible deflection, and other factors may make conventional techniques for locating the inner string 110 in the assembly 100 difficult. Therefore, having the locating device 160 in this distal location of the assembly 100 can be beneficial for determining other positions for the inner string 110 in the assembly 100.
  • each section 102A-B of the assembly 100 can have a comparable locating device 160 so positions for the inner string 110 can be determined at multiple locations when performing operations. In the end, this can help operators find the various ports 132A-B individually in the sections 102A-B.
  • the locating device 160 uses hydraulic techniques for locating the position of the inner string 110 in the assembly 100.
  • FIGs 5A-5C portion of the assembly 100 is shown with the inner string 110 disposed in a locating device 160.
  • the locating device 160 includes a tubular 161 connected by a downhole coupling 162 to the shoe track 120 and connected by an uphole coupling 163 to a ported housing 130.
  • the device 160 could be located elsewhere on the assembly 100, in which case the couplings 162, 163 would couple to other components, such as between uphole and downhole sections 102A-B of the assembly 100.
  • the device 160 can be an integral component as shown in Figure 6 having its tubular housing 161 with coupling members formed thereon. Either way, the device 160 of Figures 5A-5C and 6 has an inner passage 165 that is in fluid communication with passages 135 and 125 of the housing 130 and shoe track 120.
  • the inner passage 165 forms a sealable space with internal sealing surfaces or seats 164 disposed at both ends. These seats 164 can be internal polished surfaces with a reduced diameter from the other passages 125/135/165.
  • the inner string 110 has external seals 114 disposed one each side of outlet ports 112.
  • the seals 114 are adapted to engage the inner polished seats 164 of the couplings 161, 163 as discussed below. (A reverse arrangement may also be used in which the couplings 161, 163 have internal seals for engaging polished seats on the inner string 110.)
  • the inner string 110 also includes a valve (i.e., seat 116 and dropped ball 118) that can close off fluid flow down the string 110 and divert the flow out the outlet ports 112. Other valve arrangements could also be used, or the distal end of the inner string 110 can be permanently closed off.
  • the circulated fluid is pumped slowly down the string 110 and is diverted out the outlet ports 112.
  • the circulated fluid can be any suitable fluid used during gravel/frac pack operations.
  • the circulated fluid is water, brine, or some other type of carrying or washdown fluid.
  • the circulated fluid could include gravel packing slurry or frac treatment.
  • the circulated fluid can flow downhole in the annulus between the string 110 and assembly 100 (i.e., shoe track 120 and other downhole component).
  • the upper seal 114 of the string 110 engages the lower seat 164 of the locating device 160.
  • the outlet ports 112 reach the inner passage 165 of the device 160, and the seals 114 engage the seats 164. This creates a sealed space of the passage 165 in the device 160 that is isolated from uphole and downhole portions of the assembly's inner passages 135 and 125.
  • the sealing between the seals 114 and the seats 164 may be intended to inhibit flow and may not necessarily create a fluid tight seal.
  • the locating device 160 works regardless of the amount of pipe and drag in the inner string 110 when manipulated in the assembly 100. Therefore, at any time during operations, this known location of the device 160 can be found by movement of the string 110 and slow pumping until indication is observed so calculations to other locations can be determined.
  • Movement of the inner string 110 in the assembly 100 of Figures 5A-5C has been uphole.
  • the locating device 160 can operate equally as well with downhole movement of the string 110 in the device 160.
  • the features of the locating device 160 and inner string 110 can be used on any suitable downhole assembly in which circulated fluid from a port on the string 110 can help locate the string's position in the locating device 160 and further help determine other positions for the string 110 in the downhole assembly.
  • the locating device 160 could be used with a conventional gravel pack assembly and a crossover tool, or the locating device 160 could be used with a cementing assembly and a service tool.
  • the locating device 160 can be helpful in locating an inner string in a number of downhole components, such as locating in an extend reach frac pack assembly, a multi-zone frac system, an inflatable packer, and others. Accordingly, the above-description directed to the particular gravel pack assembly 100 is meant to be illustrative of a particular application of the disclosed subject matter.
