Well Completions

484 result(s) found.

well completions  Once a well has been drilled, specialized hardware and techniques are required to produce the well. This discipline covers various technologies used to bring hydrocarbons from the formation to the surface. Important terms range from back-pressure to tubing head and wiper plug. All definitions within this discipline have been written and reviewed by well-completion experts, and many are supplemented by high-quality illustrations.
