A method for pulling a tubular out of a subterranean well including the steps of: Further, a system for pulling a tubular was also disclosed.

Method for pulling tubulars using a pressure wave

A gun for perforating a casing, liner or tubing of a well comprising multiple perforating charges in a mounting fixture configured to rotate inside a gun carrier and orientate the charges to a predetermined direction relative to the casing, liner or tubing. The mounting fixture and the charges are carried by an orienting tube, and the orienting tube is rotatably supported inside the gun carrier, thereby creating a rotatable assembly for orienting the charges into a predetermined direction.

Gun for oriented perforation

A method for plugging a subterranean well (), comprising running a perforating tool () into the subterranean well and positioning the perforating tool in a well section (L) to be plugged; operating the perforating tool to create a plurality of holes () in a part () of a casing () located in the well section; running a surge tool () into the well; operating the surge tool () to lower the pressure inside the part () of the casing () located in the well section (L) and flowing a well fluid from an annulus () between the casing () and a well formation () through the holes (); and pumping a fluidized plugging material into the well section (L) via a tubing string ().
