Thank you very much! I’m happy to learn something every day.
It’s worth every penny you paid for it.
I second the motion to stop the nonsense about a “plot.”
I own a drilling company (land) and this stuff just happens, especially when drilling high pressure or intentionally underbalanced.
Not sure about gas coming up through cement. I can’t say I haven’t seen it, but cement is heavy and even a big bubble should have been easily controlled.
IMHO (and speculating like mad here), I would propose they were drilling underbalanced on purpose to prevent formation damage, counting on their BOP to do its job, and it didn’t do its job.
A 15,000 BOP should have a margin of safety to 30,000 or more. (Indeed, that would be what the factory tested it to and should stand, if assembled correctly.)
I never let third-parties assemble my BOPS on high pressure or intentionally underbalanced wells.
