Appl. No.:

13/908657

Inventors:

Richard J. Robichaux - Raceland LA, US

International Classification:

F16L 41/06

US Classification:

137 1513, 137318

Abstract:

A method of hot tapping into a multiple string configuration for obtaining access to the production tubing without removing outer layers of casing by providing a multiple casing string that includes at least an outer casing and an inner casing or production string; mounting a clamp assembly around the wall of the outer casing; hot tapping a small opening through the outer casing wall to capture any pressurized fluid through the opening; cutting first and second large openings through the wall of the outer casing to access the inner casing, each opening being approximately 180 degrees from the other opening; through the first opening, drilling a small hole through the wall of the inner casing to capture any pressurized fluid through the opening in the inner casing; and inserting an anvil through the second opening to contact and stabilize the wall of the inner casing to prevent the casing from moving while the casing is drilled.

Assignee:

BTI Services, Inc. - Houston TX

International Classification:

F16L 41/06

US Classification:

137 1513

Abstract:

A hot tapping assembly for hot tapping into a multiple string configuration to obtain access to the production tubing without removing outer layers of casing, the hot tapping assembly including a hot tapping clamp and a hot tapping seal assembly. In one embodiment, the hot tapping clamp includes a clamp plate having an access bore. The clamp plate can engage with an outer surface of a pipe. In another embodiment, the hot tapping seal assembly can engage with the hot tapping clamp, and includes a hot tapping tubular that can engage with the outer surface of the pipe through the hot tapping clamp's access bore.
