Abstract
Systems and methods for completing a well, involving a fracture placement packer assembly comprising an inflatable packer positioned on an uphole side of the assembly; the inflatable packer is structured to execute repeated inflation/deflation cycles in response to an inflation/deflation procedure, and wherein the inflatable packer is a self-anchoring packer; and the fracture placement packer assembly is structured to be couplable to a conveyance device.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A method, comprising:
positioning a fracture placement packer assembly, comprising an inflatable packer positioned on an uphole side of the assembly, in a wellbore at a fracture treatment position; inflating the inflatable packer; fracture treating an interval of a subtteranean formation operationally coupled to the wellbore; and the method further comprising at least one operation selected from the operations consisting of:
marking the interval before the fracture treating;
wherein the inflating the packer further comprises inflating a self-anchoring packer;
fracture treating a second interval after the first interval, wherein the second interval comprises a greater measured depth than the first interval;
fracture treating a second interval after the first interval, wherein the second interval comprises a smaller measured depth than the first interval, the method further including positioning a sand plug across the first interval before the fracture treating the second interval;
fracture treating a second interval after the first interval, wherein the second interval comprises a smaller measured depth than the first interval, the method further including positioning a sand plug across the first interval before the fracture treating the second interval, wherein the sand plug comprises a high particulate fraction fluid having a plurality of particle size modalities therein;
fracture treating a second interval after the first interval, wherein the second interval comprises a smaller measured depth than the first interval, the method further including positioning a sand plug across the first interval before the fracture treating the second interval, wherein the sand plug comprises a high particulate fraction fluid having a plurality of particle size modalities therein, and removing an amount of water from the sand plug;
performing the fracture treating with a drill string positioned in the wellbore;
performing the fracture treating with an uncemented casing string positioned in the wellbore;
interpreting at least one of pressure information, temperature information, and inflation information, determining a wear value for the assembly in response to the information, and providing the wear value to an output device;
wherein the marking comprises oriented marking;
wherein the marking comprises a selected geometric configuration;
wherein the marking comprises at least one operation selected from scoring, punching, perforating, pre-inflating the packer, gouging, grooving, and indenting;
wherein the inflating comprises an operation selected from the operations consisting of providing a pressure pulse, dropping a ball, and providing an electrical signal;
providing a liner in the wellbore, positioning a number of external packers between the liner and a wellbore face, wherein each of the external packers comprises an activatable packer, activating the external packers, and wherein the inflating the inflatable packer comprises running the inflatable packer to a selected position within the liner before the inflating;
the method having the “providing a liner” operation, wherein the selected position comprises a position aligning the inflatable packer with one of the external packers; and
the method having the “providing a liner” operation, wherein the activating the external packers comprises at least one operation selected from inflating the external packers, swelling the external packers, and mechanically activating the external packers.
2 . A system, comprising:
a fracture placement packer assembly comprising an inflatable packer positioned on an uphole side of the assembly; wherein the inflatable packer is structured to execute repeated inflation/deflation cycles in response to an inflation/deflation procedure, and wherein the inflatable packer is a self-anchoring packer; and wherein the fracture placement packer assembly is structured to be couplable to a conveyance device.
3 . The system of claim 2 , wherein the conveyance device comprises a device selected from the devices consisting of: a coiled tubing unit, a wellbore tubular; a wellbore casing; and a drill string.
4 . The system of claim 2 , wherein the inflation/deflation procedure is performed using a device selected from the devices consisting of: a pressure pulse generator; an electrical signal generator; and ball activated actuator.
5 . The system claim 2 , further comprising a wellbore having a first interval and a second interval, the second interval at a smaller measured depth than the first interval, the fracture placement packer assembly positioned at a smaller measured depth than the second interval, the system further comprising a deviation device positioned across the first interval.
6 . The system of claim 5 , wherein the wellbore at the position of the first interval is one of horizontal and highly deviated, and wherein the deviation device comprises a sand plug.
7 . The system of claim 6 , wherein the sand plug comprises a high particulate fraction fluid having a plurality of particle size modalities therein.
8 . The system of claim 7 , wherein the high particulate fraction fluid further comprises a water removal constituent.
9 . The system of claim 8 , wherein the water removal constituent comprises a material selected from the materials consisting of: fibers, a hydroscopic material, a water absorbent material, and a coated material.
10 . The system of claim 2 , further comprising a wellbore marking tool.
11 . The system of claim 10 , wherein the wellbore marking tool comprises a tool selected from the tools consisting of a scoring device, a punching device, a cladding coupled to the inflatable packer, a gouging device, a grooving device, an indentation device, a rotary tool, and a star shaped rotary tool.
12 . A system, comprising:
a straddle packer assembly comprising a first inflatable packer positioned on an uphole side of the assembly and a second inflatable packer positioned on a down hole side of the assembly; wherein each of the inflatable packers are structured to execute repeated inflation/deflation cycles in response to an inflation/deflation procedure; wherein the fracture placement packer assembly is structured to be couplable to a conveyance device; and wherein the straddle packer assembly comprises a spacer element positioned between the first and second inflatable packers, the spacer element including a fluid conductance feature and the spacer element structured to maintain the inflatable packers at a specified distance.
13 . The system of claim 12 , wherein the conveyance device comprises a device selected from the devices consisting of: a coiled tubing unit, a wellbore tubular; a wellbore casing; and a drill string.
14 . The system of claim 12 , wherein the inflation/deflation procedure is performed using a device selected from the devices consisting of: a pressure pulse generator; an electrical signal generator; and ball activated actuator.
15 . The system of claim 12 , further comprising a wellbore marking tool.
16 . The system of claim 15 , wherein the wellbore marking tool comprises a tool selected from the tools consisting of a scoring device, a punching device, a cladding coupled to at least one of the inflatable packers, a gouging device, a grooving device, an indentation device, a rotary tool, and a star shaped rotary tool.
17 . The system of claim 12 , further comprising a liner positioned across a target fracturing zone, and wherein the straddle packer assembly is positioned such that the first and second inflatable packers define the target fracturing zone.
18 . The system of claim 17 , wherein the liner is not cemented, the system further comprising two external packers positioned between a formation face comprising the target fracturing zone, and wherein the first and second inflatable packers are each positioned at one of the two external packers.
