Abstract: An adaptive seat is run in with an isolating object to beyond a landing location for the adaptive seat. The adaptive seat is released to expand and engage the surrounding tubular. Pressure from below acts on the object and propels the object against the adaptive seat. The object and the adaptive seat move in the tubular to a nearby landing location such as a groove or recess in a sub that is part of the string or another location such as a tubular joint where the adaptive seat finds support. An upper portion of the borehole is isolated for a time from formation pressure to allow running in an ESP from the surface. The object is removed by degradation or from being structurally undermined and the ESP is operated to produce the formation. One or more removable barriers are contemplated.

Abstract: A method of preparing a mounting location in a tubular disposed in a borehole features milling a support location and then releasing an adaptive support to position it in the mounting location directly or indirectly by releasing the adaptive support offset from the mounting location and then translating the adaptive support to the mounting location or directly into the support location without translating. A mill centralizing anchor compensates for internal out of roundness of the tubular. Uniformity of the wall thickness at the milling location is determined in conjunction with the centralizing feature to obtain a mounting location that extends circumferentially for as much as 360 degrees, without materially reducing the pressure integrity of the tubular being milled. The recess, groove or equivalent that is the mounting location can have planar or/and arcuate surfaces. The adaptive support can be released using stored potential energy in the adaptive support.

Abstract: An assembly of a setting tool in combination with a delivery tool for an adaptive support allows delivery of the adaptive support in a condition where it stores potential energy. Relative movement between a mandrel and a surrounding sleeve allows release of the adaptive support at a desired subterranean location. The relative movement to release the adaptive support comes from a setting tool that has a setting sleeve and a supporting connection to the mandrel of the delivery tool. The setting sleeve, when triggered to move by preferably an explosive charge, engages a piston rod assembly supported by the delivery tool mandrel for tandem movement to a mandrel travel stop. The tandem movement is regulated, preferably in the delivery tool, with regulation of fluid flow through a restriction to eliminate component failure due to high impact loads when the travel stop is engaged.

Abstract: A delivery tool creates relative axial movement to retract a retaining sleeve from an adaptive seat so that the adaptive seat can release from the delivery tool and find support in a tubular string. The relative movement is created directly with a power charge acting on a piston attached to the retaining sleeve. Movement of the retaining sleeve releases support dogs that position the delivery tool when releasing the adaptive seat. The adaptive seat is protected for running in with a collapsible ring structure that passes through the adaptive seat opening when the delivery tool is pulled out of the hole. The retaining sleeve is replaced and the power charge is renewed to allow the delivery tool to be used more than once.

Abstract: A coiled adaptive seat is held to a smaller diameter for delivery with a tool that features a locating lug for desired alignment of the seat with an intended groove in the inner wall of a tubular. The release tool retracts a cover from the seat allowing its diameter to increase as it enters a groove. Alternatively the adaptive seat is released near the groove and pushed axially in the string to the groove for fixation. Once in the groove the inside diameter of the string is a support for a blocking object so that sequential treatment of parts of a zone can be accomplished. The blocking object is removed with pressure, dissolving, milling or disintegration leaving a narrow ledge in the tubular bore from the seat that can simply be left in place or milled as well. An E4 #10 from Baker Hughes is modified for adaptive seat delivery.
