Drums Elementary has completed study of 18 offshore oil well blowouts in the Gulf of Mexico for BP plc. Faculty and parents, the cause of all 18 oil well blowouts was gas cut (lightened / thinned) drilling mud. You see parents and faculty, when drilling through an oil bearing zone, the drilling mud often becomes gas cut lightened (mud weight reduced) and thinned (mud viscosity reduced). Defoamers are added to restore the drilling mud back to a safe, non-frothy, heavy weight and viscosity. But they do not work in extreme gas cut muds. The ONLY way to fix the problem is to circulate the oil well with NEW drilling mud, and dispose of the OLD gas cut mud (a costly process, its a toxic waste). BP plc, et al, in all 18 Gulf of Mexico oil well blowouts, Operators skipped that costly step. Schlumberger logged BP plc's blowout, Horizon ran production casing, and Halliburton pumped the cement, with frothy (like a head of beer) gas cut mud in the hole. Sometimes it works, sometimes it does not. AGAIN, it did not. BP Chief, next time, circulate NEW non-gas cut drilling mud. Defoamers fail in high concentrations of gas.

BP plc Gas Cut Drilling Mud weight: 8.4
BP plc Gas Cut Drilling Mud viscosity: 42
For God's sakes think about what you're discussing. Why focus on equipment that had nothing to do with it? No body is going to help us here and we have a job to do. I have been drilling holes in the earth for thirty-three (33) years. And one thing I know with good drilling mud a well will NOT blowout. The lost circulation during cementing theory is false that did NOT happen. Some cement was slowly moving into the zones sure which is why it did not set. But with good non-gas cut drilling mud in the hole it would have NOT blown out. Engineers for BP plc et al know these facts but have been silenced by management. In any case with my thirty-three (33) years in the business I still do not know everything. However one thing I do know is with a good honey-like drilling mud a well will NOT blowout. Gas, oil, and drilling mud blew out of the annulus NOT the inside so pipe integrity was maintained. The casings failed when the vessel sank not before however Cameron's blowout preventer DID fail. Well guys that's my two-cents worth just would like to see discussion about the light gas cut drilling mud. Thank you.
God bless the families of our 11 friends killed by BP plc's gross negligence.

David, by *light* gas cut drilling mud (the density weight) I mean *high* gas cut drilling mud (gas concentration). Sorry, clarification made here. The Chief of BP plc faces a grilling in Washington today. He will TRY to avoid discussing the frothy *light* Gas Cut Drilling Mud which was in the tanks, the riser, and the hole of Macondo well, Mississippi Canyon Block 25, while IT was being logged, casing run, set and cemented. BP plc's Attorneys (lawyers) have instructed Tony Hayward to shift the blame towards Contractors, especially *their* equipment. Congress will NOT be fooled by the BP Chief's antics, frothy *high* Gas Cut Drilling Mud, weight 8.4, viscosity 42, caused the blowout. All of the 18 blowouts in the Gulf of Mexico while cementing the same. Change out your drilling mud guys if the defoamer fails to knock the gas out of it. Thank you.

How do we know there was gas-cut mud in the hole? Earlier reports have Tidewater boat offloading mud when incident happened.

By the Macondo well's drilling mud viscosity and the Macondo well's drilling mud weight. Tom you know the laws of physics do not cease to exist in this well (or the 18 others). We are all aware Tidewater, et al, offloads mud before any rig moves.
Hydrostatic pressure = weight of drilling fluid (the *true vertical depth*) acceleration of gravity (m/s^2). You know if the hydrostatic pressure is greater than or equal to formation pressure, the formation fluid will not flow into the wellbore.
Tom there is no mystery as to what happened... Again.
The Chemical Safety and Hazard Investigation Board later concluded that the explosions were caused by company deficiencies "at all levels of the BP Corporation"—including repeated cost cutting that affected maintenance and safety. The Justice Department, working with EPA investigators, launched a criminal investigation that resulted in a $50 million fine against the company for violating the Clean Air Act.
