Method for removing condensables from a natural gas stream

摘要

A method for removing condensables from a natural gas stream upstream of a wellhead choke connected to a subterranean formation, the method comprising the steps of: (A) inducing the natural gas stream to flow at supersonic velocity through a conduit and thereby causing it to cool to a temperature that is below a temperature at which condensables will begin to condense forming separate droplets and/or particles; and (B) transporting the gas and/or the condensables to a wellhead and/or re-injecting it into the subterranean formation from which it has been produced, or into a different formation, with the proviso that not all of the collected gas and condensables are re-injected into the same reservoir zone of the same formation. A well completion system for producing gas from a subterranean formation wherein said method is applied is also included.
