ABSTRACT:
A well surface control system for use with various types of work strings such as, but not limited to, drill strings, coiled tubing, snubbing pipe, electric line, production tubing, and wireline. The system includes a main housing with a main bore extending from one end to the other. The main housing is equipped with a side port which communicates with the main bore between the two ends. The main housing is also equipped with two valves for controlling fluid and/or gas flows through the main bore and for severing a component of a work string running through the main bore. The first valve is positioned between the side port and one end of the main housing and the second valve is positioned between the side port and the other end of the main housing. Attached to each end of the main housing is a saver sub, with means for temporarily locking the saver subs to the main housing to prevent circular and longitudinal movement of the saver subs in relation to the main housing.
