  • Patent number: 9951578
    Abstract: A borehole barrier comprises a scroll where the overlapping parts have a ratchet for radial expansion against a surrounding tubular with the ratchet controlling springing back. The outer surface can have carbide or other hard particles to penetrate the surrounding tubular for fixation. The end of the scroll forms a tapered ball seat. Expansion into place can be with a tool, or by releasing potential energy in the scroll or by using a shape memory alloy that enlarges at above its critical temperature. The scrolls can be removed by milling or allowed to dissolve or disintegrate with exposure to well fluids. The scroll design is quickly deployed and removed and is far more economical than known plugs that have the traditional seal and slip design. The balls can be milled out with their associated scrolls or flowed to the surface with produced fluids.

  • Publication number: 20180045015
    Abstract: In a fracking context the object that will ultimately block a passage in an isolation device is introduced into the zone with the bottom hole assembly. The object is not released until the guns fire to create a pressure spike in the borehole that triggers the object retaining device to release the object. The retaining device is placed in close proximity to the isolation device and its setting tool to allow a larger object and passage in the isolation device to be used. If the guns misfire, the object is not released and comes out with the guns. The replacement guns can be pumped in because the passage in the isolation device has stayed open during the misfire. Direct and indirect object release in response to pressure created from the firing of the guns is contemplated.

  • Publication number: 20170342794
    Abstract: A borehole plug or packer for treating is designed to be milled out after use. The plug handles differential pressure from above using a lower slip assembly under a sealing element. A setting tool creates relative axial movement of a setting sleeve and a plug mandrel to compress the seal against the surrounding tubular and set the slips moving up a cone against the surrounding tubular to define the set position for the plug. The set position is held by a split lock ring having a wedge or triangular sectional shape and a surface treatment facing the mandrel that slides along the mandrel during setting movement but resists opposed reaction force from the compressed sealing element. The surface treatment can be a series of downhole oriented ridges such as a buttress thread that preferably penetrate the mandrel when holding the set position.

  • Patent number: 9828827
    Abstract: A composite plug that can be used in fracturing has backup rings for the seal that are preferably made of a composite material. The backup rings are essentially connected segments that allow the connections to break when the plug is set and the cones are brought closer together. When the rings break to form gaps between segments in a specific ring, the adjacent ring has offset gaps so that as a whole there are no extrusion gaps that would allow the seal element to pass. The rings can be rotationally locked to each other initially at the adjacent segments that are formed when the plug is set to maintain their relative positions so that gaps between segments adjacent the seal are overlapped with segments from the adjacent ring. The segmenting backup rings can be used on one or on both sides of a sealing element.

  • Patent number: 9797211
    Abstract: A vibratory tool for use in a tubular string to prevent sticking or to release a stuck string features a fluid operated dart valve working in conjunction with an impact sleeve to deliver continuous axial jarring blows in opposed directions as long as flow is maintained. Movement of one of those components axially in opposed directions opens and closes access to opposed lateral ports so that a lateral vibration is also established as flow cyclically occurs and stops sequentially at opposed lateral outlets.

  • Patent number: 9708881
    Abstract: In a fracturing application a packer for a given zone to be fractured is reinforced during fracturing with an insert that is preferably a sleeve. During times of high collapse pressure loading, the sleeve provides the needed support. When fracking is over the liner sleeve is caused to disappear. The preferred material is controlled electrolytic materials but other materials that can disappear when the anticipated loading is diminished can also be used. The disappearing can be motivated chemically or thermally among other contemplated methods. As a result, there is a larger available bore when production is ready to start.

  • Patent number: 9695666
    Abstract: A backup ring design for a packer sealing element features a folding shape where opposed legs are pushed together for extension in a radial direction toward the surrounding tubular to span the extrusion gap. The design can use a V-shape where the vertex is toward the mandrel and the legs are oriented toward the surrounding tubular. The legs in that instance can be thicker than the vertex thickness to aid in folding while providing enhanced strength at the surrounding tubular where shear forces apply as a result of seal compression against the surrounding tubular. The design features a single or multiple vertices that are similarly aligned or alternatingly oppositely aligned to create a zigzag shape in cross-section. Material selection can vary with the expected service conditions.

  • Publication number: 20170159146
    Abstract: A process for hardening tubulars and increasing their surface area for heat transfer can be performed in place in a borehole or on the surface. A pattern is applied to an interior wall with at laser, electron beam or radiation source that is remotely controlled to apply the hardening pattern to the inside or outside wall as inert gas or clean fluid is applied. Pressure differential is applied to the wall so that the non-hardened portions or the negative of the hardened pattern plastically or elastically deform to increase surface area and enhance load resistance of tubular or sheets. Alternatively, wall differential pressure is applied with an insert having a raised pattern on its exterior surface causing the spaces where the pattern is absent to plastically deform to enhance surface area. When done in a borehole annulus pressure or stand pipe pressure is applied or a vacuum is pulled inside the tubular to generate differential pressure for hydro-forming or switching dents in an opposite stable condition.

  • Patent number: 9617822
    Abstract: A setting assembly for a packer seal features peripherally mounted rod pistons that abut the seal to be set by advancing the seal relative to a tapered surface. When parts of the seal engage an inner tubular wall before other parts of the seal the continuation of application of hydraulic pressure to the pistons moves parts of the seal that have yet to make contact with the tubular wall further relative to the ramp so that plastic deformation of the seal assembly can occur to allow portions thereof to move radially further outwardly to seal in the region where the radius of the tubular is enlarged. When hydraulic pressure is applied to the pistons in an opposite direction a lock mechanism is defeated and the c-ring or scroll reverts to a smaller shape optionally aided by a garter spring so that the packer can be selectively retrieved.

  • Publication number: 20170096876
    Abstract: An intelligent dart or ball or other shape is dropped or pumped into a borehole that has multiple valves for access to the formation through which fractures are initiated. The intelligent object engages with the valves as it passes with retractable engagement dogs that are outwardly biased but not to the degree needed to find support unless the valve in question is the one that needs to be operated. In that event the dogs become supported and pressure is applied to the object to shift the valve to the open position. The object can be released at a later time remotely or can be milled out. Subsequent objects can be landed in the same sleeve after the initial object is released to close it or to close the open port by moving a second sleeve against a first sleeve. Fracturing in any order is envisioned.

  • Publication number: 20170067314
    Abstract: A first sleeve is shifted with a ball landed on a seat to open treating ports. At the conclusion of the treating such as fracturing, another ball is dropped on a seat in an adjacent sleeve. The adjacent sleeve shifts to contact the initial sleeve that was shifted earlier. When the sleeves abut the treating ports are closed by the second sleeve and the production ports that are preferably screened are also opened by the shifting of the second sleeve against the first sleeve. The first sleeve hits a travel stop in the housing to produce the full open position for the treating ports. The balls can be progressively larger in a bottom up direction for the procedure or the balls can all be the same size as the landing of a ball on the first sleeve reconfigures the sleeve above for the same sized ball.

  • Publication number: 20160319645
    Abstract: A wire cross-sectional shape for a wire wrap screen provides a primary and secondary gap with a contained circumferential volume in between. The secondary gap extends screen life by taking the place of the primary gap if erosion opens the primary gap and lets the larger solids get past. The closed space between the primary and secondary gaps also has the effect of reducing velocity due to the enlarged volume before the secondary gap is reached while also creating turbulence between the gaps to slow the fluid velocity to protect the secondary gap. All or parts of the wire outer surface can optionally be coated to extend service life.

  • Publication number: 20160290109
    Abstract: A gravel pack of screen sections separated by blank pipe is accomplished with sleeves around the blank sections that have a smaller run in dimension to allow the gravel to get past the sleeves during the gravel packing. When the gravel packing is complete the sleeves swell or otherwise enlarge to fill the voids where no or insufficient amount of gravel has been deposited. The presence of the enlarged sleeves prevents settling or shifting of the gravel pack away from the screens because voids that would otherwise have been there are filled with the enlarged sleeves. This is more of an issue in wells that are closer to vertical than horizontal.

  • Patent number: 9359871
    Abstract: A basket is attached below a retrievable bridge plug used during the pressure testing of a well to verify integrity prior to fracturing operations. After the pressure integrity test above the plug, the plug is released and retrieved and a series of balls of increasing diameter are dropped on increasingly larger ball seats to allow shifting sleeves to an open position from the heel of the well toward the surface to sequentially frac in that direction. If any segments of the sealing element break off they are captured and removed in the basket that has flow through opening small enough to retain the debris and allow flow through the basket during removal. The basket is slotted for through fluid flow and can have a breakaway for the support rod if the basket sticks when the plug is removed.

  • Patent number: 9353590
    Abstract: A subterranean debris catcher swirls the incoming debris laden stream by putting grooves or spiral projections on the inside of the inlet pipe. The solids come out of openings in the side of the inlet pipe or the solids can exit near the top either directly into the enclosed solids holding volume as the liquid exits straight out or the solids can be discharged out the end of the inlet pipe into the bigger open space defined by the housing. In the latter case the inside housing wall can have a screen or vanes that slow down the solid particles as the fluid continues to a housing exit and eventually to an exit screen before being discharged to either go to the surface or recirculate back along the outside of the tool to the inlet pipe while picking up additional debris.

  • Patent number: 9341044
    Abstract: A self energizing structure can function as a centralizer or as a seal when allowed to spring out after a retainer is moved away from an overlying position for run in to protect the structure. Segments extend from a common base ring and are radially offset during run in. Alternating segments have landing surfaces on opposed ends such that on release of the structure the intervening segments land on such surfaces to form a cohesive single layer with all segments circumferentially aligned and against a surrounding tubular or the borehole wall. The structure is held retracted with a bi-directionally movable sleeve operable in a variety of ways from the surface. Internally the sleeve has splines to push the segments with the landing surfaces back so that the structure can collapse back into the sleeve for removal. Structures can be stacked and used as centralizers with alternating segments removed.
