Tubular cutting with a sealed annular space and fluid flow for cuttings removal

摘要

A method of cutting and removing a tubular from a subterranean location, comprising: running into the tubular a cutter mounted on a mandrel of a spear; deploying an anchor on an outer assembly of said spear to selectively engage a first desired location within the tubular; pulling tension on the tubular through said anchor with said mandrel axially stationary as said mandrel is continuously rotated to cut the tubular, said tension at least offsetting the weight of a segment of the tubular produced by said cutter; sealing off an annular space about said outer assembly with a seal around said outer assembly when the tubular is cut; disposing said seal on said outer assembly in a manner that allows flow exiting a flow passage of said cutter to selectively reach a surface location.
