Abstract
A multifunction blowout preventer has a housing formed from a single piece of material, which has a central bore, a bottom connection, a gate valve section, an integrated ram assembly/flow tee section, and a top connection. The blowout preventer optionally includes a gas lift/electrical ports section. The components of the blowout preventer are radially offset and/or staggered from one another about the periphery of the housing to help minimize the height of the blowout preventer.
