Wireline derrick, system, and process

A wireline derrick system, the system comprising:

• a wireline derrick, and a transport trailer;
• the wireline derrick comprising:
• an elongated frame and a pressure control equipment string;
• the elongated frame being moveable from a horizontal position to an upright position;
• the elongated frame, when in the upright position, comprising upper and lower ends;
• the upper end being adapted to be coupled to a sheave adapted to receive a wireline;
• the pressure control equipment string comprising pressure control equipment;
• the elongated frame comprising a longitudinal cavity, the pressure control equipment string being longitudinally positioned within the longitudinal cavity and secured to the elongated frame both in the horizontal position and in the upright position, such that, when the elongated frame is in the upright position, the pressure control equipment string is positioned below the upper end;
• the transport trailer comprising:
• a deck and a support member, the support member being adapted to be removably and pivotally coupled to the wireline derrick;
• one or more hydraulic cylinders adapted to move the wireline derrick from the horizontal position to the upright position;
• the wireline derrick being structured and arranged to be removed from the transport trailer and moved to a position proximate to a wellhead such that the pressure control equipment string positioned within the longitudinal cavity is in axial alignment with the wellhead.

A wireline derrick deployment process, the process comprising the steps of:

• providing a wireline derrick and a crane, the wireline derrick comprising:
• (a) an elongated frame comprising a telescopically arranged lower section and upper section;
• (b) a winch assembly;
• (c) a pressure control equipment string comprising a lower PCE assembly and an upper PCE assembly, the pressure control equipment string being longitudinally positioned within a longitudinal cavity of the elongated frame and secured to the elongated frame both in a horizontal transport position and an upright position;
• providing a transport trailer;
• using the transport trailer, moving the wireline derrick from the horizontal transport position to the upright position;
• extending the upper section from the lower section;
• moving the upper PCE assembly into axial alignment with the lower PCE assembly;
• coupling the upper PCE assembly with the lower PCE assembly;
• securing the upper section to the lower section;
• using the crane, removing the wireline derrick from the transport trailer and moving the wireline derrick to a position proximate to a wellhead such that the pressure control equipment string positioned within the longitudinal cavity is in axial alignment with the wellhead.

A wireline disengagement process, the process comprising the steps of:

• providing a wireline derrick, a transport trailer, and a crane;
• the wireline derrick being in a deployed condition and at a position away from the transport trailer, the wireline derrick comprising:
• (a) a telescopically arranged elongated frame comprising a lower section and an upper section;
• (b) a winch assembly;
• (c) a pressure control equipment string comprising a lower PCE assembly and an upper PCE assembly, the lower PCE assembly and upper PCE assembly being secured to the elongated frame;
• the lower section being secured to the upper section;
• the lower PCE assembly being coupled to the upper PCE assembly;
• disengaging the upper section from the lower section;
• decoupling the upper PCE assembly from the lower PCE assembly;
• moving the upper PCE assembly out of axial alignment with the lower PCE assembly;
• using the crane, and with the lower PCE assembly and upper PCE assembly secured to the elongated frame, moving the wireline derrick to a position proximate to the transport trailer;
• retracting the upper section into the lower section;
• using the transport trailer, and with the lower PCE assembly and upper PCE assembly secured to the elongated frame, moving the wireline derrick from an upright position to a transport position on the transport trailer.
