Schlumberjargon 

A collective term for technical (and often confusing) oilfield shop talk.

Oilfield Engineer A: "Hey, we need to do an RST and a PLT in this well. Somebody call Schlumberger."

Oilfield Engineer B: "Shouldn't we run an SCMT and a CHFR in addition to the RST?"

Oilfield Engineer A: "Nah, on second thought, we'll just P&A."

Normal Person: "Hey guys, shut up with all the Schlumberjargon and let's just do the job!"
