SG2,
"Watched the Deepwater movie t'other night. Any chance of a brief on the discrepancies?"
OK, you asked for it! The list is not exhaustive. Nevertheless a good bit of oilfield-related weekend O/T about a thing which was 'systems failure' at multiple levels. 'Wrong stuff' in the movie...
1 Gas bubbles from seabed: nonsense; never happened.
2 Post home regarding 'bad feelings about the well': maybe partially true, but not sent by that person.
3 Standby boat captain discussing downhole test ops: would never happen, and didn't.
4 Bird strike on chopper: dramatic, though none reported during the entire period.
5 Mech (on arrival) going to rigfloor and asking a roughneck about Schlumberger's operations? Would never happen, none of his business, neither of them would understand subject anyway.
6 'Whiteboard presentation', OIM / Co-Man, plus others. (Mech wouldn't have been present.) The cement which wasn't CBL (Cement Bond Log) tested wasn't just below the BOP as shown. It was around the production casing, 15,000 metres deeper.
7 The Transocean OIM wants a 'negative test'. Wrong. It was one of the BP Co-Men who said this had been ommitted from the plan.
8 Rotting the rig for the test? Pure Star-Trek. Didn't happen, no reason to do so, impossible, anyway.
9 Footage of external 'piston-like' movement on the subsea BOP? Pure imagination. Doesn't resmble a BOP at all.
10 Downhole gauges relating to the drilling rig and the well on the 'bridge'? Nope. Not there. The 'maritime' crew wouldn't understand what they were indicating, anyway.
11 Supply-boat watching the test? Same as above. No way.
12 Rigfloor footage of the test setup pipework. Just wrong.
13 'Automated voice' announcing pressures during ongoing test: more Star Trek. Doesn't happen. 'Need to know' only.
14 Turning on the lights for nighttime! That made me laugh! ALL drilling-rig (land or marine) illumination is left running, be it day or night. (Sure, in the desert I sometimes turned off my office desk lamp in daytime, but that's different.)
15 Overflow of mud over the shale-shakers. No. Not yet...
16 Mud coming up through the rotary-table. Idem.
17 The sequence of closing the annular BOP and seeing that had failed is completely wrong.
18 After power-blackout, assorted screens are shown as operating. Wrong. Many had no battery backup. The instruments were down.
19 The crane sequence / collapse of the derrick is wrong.
20 Attempt to start emergency generator (which should have been automatic, (but failed because the DWH was a rustbucket) is also wrong, by all witness / participant accounts.
Plus also, the overriding thing in that 'first half' was the undisguised animosity portrayed between BP and TO staff. Things would never have got to that level. Or at least not on any of the rigs I've been on, which are many. Someone would have got a one-way chopper ride home before things came to that.
Of course, the second half was Hollywood bang-bang. I foungd the endi
