Completion - Drilling or Production?

[Yengineer]

Completing the well is a process per se'. It does not belong to any of them. Usually the big companies have e drilling/completion/WOver department where different guys cover different areas of expertise. Small companies contract the work out to engineering companies which can do both.

Ok, I understand that. But when you say E&P, completion belongs to E or P?

I'm asking that because I had a discussion with my mastering teacher and he said that its in scope of production department of a company. I know that there is a team that is responsible only for completion, but if you have to define it to drilling or production, I would choose drilling. Even so, in general, the same rig that drill a well usually does the completion. Do you agree with me?

Completions has historically been a subset of Production. Most university courses now teach completions as part of a Production Technology course within a Petroleum Engineering degree.

Similar to the way Reservoir Engineering has been born out of general Petroleum Engineering as the need to better understand the effect of PVT fluid behavior on recovery, Completions Engineering arose out of a perceived gap between Drilling Engineering and Production Engineering. Traditionally, Production Engineers/Technologist would design a completion in different stages based on uncertainty, i.e. conceptual design, detailed design etc. and Drilling Engineers would just follow the procedure written by PT's. Note that a Drilling Engineer's main role ends when they have reached TD and have set a cement plug, but since the rig is still under the watch of the D.E., the D.E. must be involved and on standby if drill pipe and rig facilities need to be used during completions. However, since PT focuses deeply on parts of R.E. type studies, there is usually a lack of operational expertise. This is where the completions engineer comes in. The C.E. is therefore a hybrid between a Production Engineer and a Drilling Engineer.

In either exploration or production activities, all disciplines are involved. Completions engineer is a subset of well engineering.
