If there are indications of bad cement they can perform a remedial cement job.



What this guys says. In the oilfield terms it's called a "squeeze job". You run in the well with a cement stinger assembly or a RTTS tool and you force more cement around the casing and the formation.

If they had a suspicion the cement job was not good (which they did) they should have run a CBL (Cement Bong Log) on wireline which should have shown them whether or not the cement job was good or bad. They had the equipment on the rig to run the CBL but skipped it because it consumes time and money.

The movie made a salient point out of this situation and portrayed Vidrine as the strongest advocate AGAINST running the CBL and running other remedial operations for the suspect cement.

I don't know whether this is true. I don't know whether any of the movie is true. I suspect that the BP company's engineers don't agree with the movie.
