ABSTRACT:
A method and apparatus for testing blowout preventer systems that enables testing of various size pipe rams, as well as safe and efficient shut-in of a well, without having to trip the entire apparatus out of a well. The testing apparatus generally includes an upper elongated testing cylinder, an upper test seal assembly, a lower elongated testing cylinder, a lower test seal assembly and a test plug. Additionally, the testing apparatus may include a circulating flow assembly, a side-port assembly, and a check-valve assembly, all of which are axially connected in a series to allow the testing tool to be easily lowered into a riser to a subsea blowout preventer assembly. The subject invention permits testing of blowout preventers that are designed to seal around various size pipe diameters during a single pipe trip. The invention also allows the operator to efficiently and safely shut-in a well if a kick is experienced during testing operations.
