Last week’s oil platform explosion in the Gulf of Mexico may have been caused by a pressure surge, a risk that could grow as restrictions on offshore drilling are loosened by the Obama administration and companies drill deeper beneath the sea floor. At wells that go 10,000 feet or more below the surface — last week’s blast occurred at a well 18,000 feet deep — there is increased risk of extreme pressure and high temperatures that can crush steel and cause towers of flames, Bloomberg news reports.
While the Minerals Management Service inspects wells every 30 days, at least one was shut down in recent years because of concerns from within an oil company. In 2006, Exxon Mobil abandoned a well nearly seven miles beneath the seafloor in the Gulf of Mexico because engineers were concerned with the pressure levels and temperatures, according to Bloomberg.
Also, in a Q&A with the Houston Chronicle, an offshore oil worker talks about the job’s dangers:
Q: Given what happened in the Gulf on Tuesday, are you apprehensive about going back out?
A: I feel bad for the people out there, and I don’t know what happened, but it doesn’t really weigh on my mind when I’m out there. With technology today, I feel just as safe out there as I do here. You have so many safety meetings. Things happen, things can happen, but does it bother me? No.



Can you give me an idea of the kind of pressures that can be expected in deep well drilling be it on or off shore.
What were the pressures at the time of the BP incident.
