I found this glossary on Schlumberger’s website. Any jargon or terms you are unfamiliar with, look them up here. There are even a lot of slang terms used for the types of workers. I pasted a couple I really liked below.
WEEVIL a.k.a WORM
|1. n. [Drilling]||ID: 1658|
A new, completely inexperienced member of the drilling crew. Such a crewmember is stereotyped as prone to making mistakes and being injured, and typically endures pranks played on him by the drilling crew. While the terms weevil and its close cousin, worm, are used widely, they are labels of inexperience, rather than derogatory terms.
|. n. [Well Workover and Intervention]||ID: 4600|
The application of tools, equipment and techniques for the removal of junk, debris or fish from a wellbore. The key elements of a fishing operation include an understanding of the dimensions and nature of the fish to be removed, the wellbore conditions, the tools and techniques employed and the process by which the recovered fish will be handled at surface.
