Abstract
A well system and method including applying suction to a wellhead housing outlet () to divert the flow of subterranean gas from flowing through a gas conduit through the wellhead housing (). An operation can then safely be performed on a component (e.g. removing a hanger) of the wellhead apparatus. Well gas can be diverted to a flare system (). Suction can be applied by a venturi system including eductors (). The method may include opening the gas conduit outlet once a pressure sensed at the conduit outlet is negative. Suction may also be applied to an upper outlet ().
