Abstract: A tool for holding a well column pipe, the tool incorporating a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end; a seam extending oppositely laterally from the plate's lateral end, the seam dividing the plate into longitudinal and oppositely longitudinal segments; a hinge connected operatively to the plate at a lateral end of the seam; a releasable latch connected operatively to the plate at an oppositely lateral end of the seam; a jaw connected operatively to a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, the jaw being adapted for frictional engagement with the well column pipe; and a jack screw actuator for driving the well column pipe against the jaw.

Abstract: A well column pipe retrieval tool incorporating a “U” bracket having a lateral arm and an oppositely lateral arm, wherein the oppositely lateral arm has a fixed segment and a moveable segment; the column pipe retrieval tool further incorporating a column pipe receiving throat which is laterally bounded by the “U” bracket's lateral arm, and which is oppositely laterally bounded by the oppositely lateral arms' moveable segment; the column pipe retrieval tool further incorporating a plurality of pin and angled slide slot combinations which interconnect the oppositely lateral arm's fixed and moveable segments.

Abstract: A tool for holding a well column pipe, the tool incorpo-rating a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end; a seam extending oppositely laterally from the plate's lateral end, the seam dividing the plate into longitudinal and oppositely longitudinal segments; a hinge connected operatively to the plate at a lateral end of the seam; a releasable latch connected operatively to the plate at an oppositely lateral end of the seam; a jaw connected operatively to a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, the jaw being adapted for frictional engagement with the well column pipe; and a jack screw actuator for driving the well column pipe against the jaw.

Abstract: A catch tool for retrieval of a well column pipe having a pipe wall, the catch tool incorporating a fork having a pair of spaced tines; and a pair of clamping pivot arms connected operatively to the fork, the clamping arms being adapted for, upon the receipt by the tines of the pipe wall, grasping the pipe wall; the clamping arms having proximal and distal ends, the arms being adapted for pivoting movements between first and second positions, the arms' distal ends being displaced away from each other a distance less than the pipe wall's thickness dimension while in the first position, and being carried by the pipe wall to their second positions.
