Question: Why did Vidrine not think there was anything wrong with the drill pipe, even though the drill pipe test showed a lot of pressure? Second, why did the test on the kill line show no pressure?

Visible crew/equipment: Near the end when Mark is walking into the hotel, the reflection of the camera operator can be seen to the left in the door. (01:34:00)

Suggested correction: There is also the world media outside filming the survivors entering the hotel. To say it is a camera operator, while statistically true, can't be classed a mistake as we don't know if it's a member of the media.
This is the actual camera filming the shot. That's a mistake.

Question: Is it true Jimmy Harrell was taking a shower as the disaster began?
Answer: Yes. There are actually many cases where the actors portray what the actual people were doing at the time of the disaster. Another example is when the guy (I can't remember his name off the top of my head) rubs mud off the main drill pipe.
Answer: Yes.

Question: What causes pressure in an oil well?
Answer: That largely goes back to how oil is formed: from dead organic material. That sinks to the bottom of the sea, and if certain layers of sediment build up over that, it gets buried deep enough that's it's compressed, and after enough time passes, it becomes oil. But that pressure from the massive weight of miles and miles of rock on top of it never actually goes away, so when you poke a hole in it, that pressure suddenly has a way to go, via the oil spewing up through the well.
So basically the pressure is created by massive weight of miles and miles of rock on top of the oil that creates the well pressure. Is that correct?
Geologic forces are one thing, but there are different types of petroleum wells, ranging from crude oil to natural gas to combinations thereof. The lattermost, a oil/gas well, is most dangerous because it can suddenly start spewing natural gas when crude oil was expected. Tapping into an oil/gas well can be like popping the top on a can of soda: Gases are released from the fluid and expand rapidly, creating immense and unexpected pressure. In the case of the can of soda, the thing unexpectedly spews soda all over you and your clothing. In the case of an oil/gas well, the thing unexpectedly undergoes a gas blow-out and, potentially, a catastrophic explosion when it reaches the surface.

Answer: Vidrine didn't think there was anything wrong with the the drill pipe because there was nothing wrong with it. The problem was the cement cap they tried installing to seal the well. The thing to keep in mind is that British Petroleum didn't intend to immediately tap that well. Managers and crew of the floating platform rig planned to just cap the well and let another rig come along to handle actual production later. The crew was thus a little anxious to cement the well closed and abandon it. Some think it was this anxiousness to move on that produced the blowout. Of many procedures performed prior to abandonment was the "negative test" (whereby drilling mud was pulled out of the well to determine whether the cement cap could withstand the pressure). The negative test was bad, showing pressure in the drill line, an indication that gas had entered the well because they were applying suction to it, and the integrity of the cement cap was compromised. That's when Vidrine ordered the second test, this time on the kill line, and got a reading of no pressure (which was good, but was probably a false reading). Obviously, something wasn't right; but Vidrine, anxious to wrap the operation, decided to trust the kill line reading and basically ignore the drill line reading. This was a major mistake. As they continued pulling the drilling mud out, highly-pressurized gas shot straight up the drill pipe to the rig, and that was the end of Deepwater Horizon.

In the movie, the reason the kill line got no pressure is because the pipe got clogged. (if you listen to the audio description, you'll hear the audio describer the mud clogs the pipe during the kill line pressure test scene).
I thought it was mud that shot straight up from the drill pipe to the rig.
They were sucking the drilling mud up the pipe, but there was high-pressure petroleum gas behind it. They only realised too late that they had failed to cap the well; and then hell, as they say, broke loose.

Then what was that fluid flying upward through derrick?
You can liken a gas blow-out to somebody popping the top on a pressurized can of soda; gas and fluid alike come spewing out of what was, a moment before, a fairly stable fluid. Under tremendous pressure, all you need to do is give natural gas an escape route and all kinds of stuff comes up with it, including crude oil, asphalt, drilling mud, water, etc. The gas is blasting out of the earth and carrying anything and everything with it.

The mud contained a certain methane gas proportion, which ignited and caused the explosions.
Authorities don't think Vidrine was ultimately responsible though. They believe the an employee who died in the disaster was, because he was responsible for the bladder effect hypothesis. I think what the film is actually trying to say is that the person who made the mistake of trusting the kill line was ultimately responsible.
In real life, it was Vidrine who chose to trust the kill line reading and ignore the drill line reading.

By blaming someone who isn't around to defend themselves as they died in the disaster is considered cowardly. That's why in my opinion, money exchanged hands between BP and the Authorities to ensure no charges were brought against Vidrine. Again that's my own opinion. Here's a link to where the manslaughter charges against Kaluza and Vidrine are dropped https://www.theguardian.com/environment/2015/dec/03/manslaughter-charges-dropped-bp-employees-deepwater-horizon-oil-spill.

Personally I think the idea that the actual villain was the guy who was responsible for the bladder effect hypothesis, and not the guy who chose to trust the kill line reading, and not the drill line reading is absurd.
