Yup, at the end of the day the buck stops with the people on board that rig. Major missteps and/or blatant disregard were major contributors. There are some serious head scratchers as to the actions of the rig personnel.

The theatrics of the movie didn't bother me too much. Except the damned oil coming from dinosaurs!!!!. But I expected them to make it a bit dramatic. But the way they treated BP was over the line and I blame BP! haha. Especially the completion engineers (which I am an engineer in completions so I'm partial)was laughable. Like they were bumbling retards who didn't know anything about the oilfield or how to act on a rig. And how Transocean knew everything. Transocean is a rig company and you hire them to run your rig. They aren't drilling engineers. They have their rules and regulations of what they will and won't do, but they typically do what they are told and the operator makes the call. Again, all that didn't bother me a whole lot.

What did bother me was that apparently the rig was shooting shrapnel constantly. When marky mark jumps in the water, it looks like an army with automatic rifles is shooting directly at him. Yet he never gets hit. Where is all this shrapnel coming from and how did no one die from it????

This probably would have been caught by a FIT test... not sure if/why they didn't do one. I didn't look to see if they did.

I've been around hundreds of wells and never seen a cement bond log done ever.

They make Thixotropic and other really hot cements for situations like that. Flip side is a consultant or engineer not watching what he's doing can cement up a lot of drill pipe real fast. Had a guy tell me he got in an argument with a consultant when he told him the wet string they were pulling after a thixo squeeze job was cemented pipe. Consultant ruined about 5,000' of drill pipe and got fired to boot.

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.

They had tanks on the rig filling up with well bore fluid. Which means the well was slowly flowing back. I've seen the graphs. They ignored the alarms because they were offloading the same fluid and just assumed tank levels were all messed up due to that.


I saw the movie only once, but, I think I recall this point being part of the movie, which makes sense because of the dramatic tension created between the characters who wanted to heed all warnings and run more tests and those who didn't.

The movie is a good piece of film-making, but, for all I know, it might be pure fiction -- most films that cover real events are heavily fictionalized.

When all this happened, I thought the story was that they HAD run the CBL but misinterpreted the log. If they didn't even run one, then holy shite. What's a CBL cost these days? $10-20k?

Well that shows you how long I've been out of it. When I was in the oil patch (I designed CBL tools), they were SOP.

I saw the movie only once, so, I'm going by memory of a single viewing -- not the most reliable source.

In any event, I have never seen an entertainment product from Hollywood that was based on a real event that was not heavily fictionalized.

I will go so far as to say that almost every entertainment product from Hollywood that portrays a real event is significantly fictionalized.

Try in the hundreds of thousands to over a million depending on what data they actually gather. That's just for the service provider. Not to mention rig time and all other costs that go along with it.

I've got a cousin that lost his shite when the guy touches the mud on the drill pipe and the mud begins to seep up through the derrick floor.

Things aren't cheap in deepwater. They had the CBL crew and equipment on the rig. The crew flew in that morning when they decided they weren't going to run the log. We'll never know, but it could've prevented the disaster.
