Abstract
A method for a well intervention operation may be conducted on a wellbore having a subsurface safety valve in a tubular string therein with a wireline extending into the wellbore from a wellhead. The method may include deploying an opening sleeve tool into the wellbore; landing a top portion of the opening sleeve tool on the subsurface safety valve; forcing a gate valve of the subsurface safety valve with a tubular portion of the opening sleeve tool from a closed position to an open position; and conducting the well intervention operation.
Claims8
A system, comprising:
- a wellhead on a surface of a wellbore, wherein a blowout preventer is disposed on top of the wellhead;
- a tubing string disposed within the wellbore;
- a cable extending downward into the wellbore from the blowout preventer and the wellhead, wherein the cable is connected to a bottomhole assembly within the wellbore;
- a subsurface safety valve disposed in the tubing string;
- and
- an opening sleeve tool attached to the cable, the opening sleeve tool comprising:
- a top portion configured to land on an upper most end of the subsurface safety valve;
- and
- a tubular portion defining a bore extending downward a length from the top portion,
- wherein an end of the tubular portion distal to the top portion is configured to force a gate valve of the subsurface safety valve to move from a closed position to an open position;
- and
- wherein an inner diameter of the tubular portion is greater than an outer diameter of the bottomhole assembly.
