We’ve been trying to document as much data about BP’s Mississippi Canyon Block 252 well blowout that has now been flowing uncontrolled for 25 days. The public is finally waking up to the fact that the well is likely flowing much more than the 5,000 barrels per day that BP and the Coast Guard continue to estimate. SkyTruth, geologist John Amos’s blog, continues to estimate the flow at 26,500 barrels per day based on satellite imagery. A new estimate, made by Steve Wereley, a professor at Purdue University, placed the flow at 70,000 barrels per day using a technique called particle image velocimetry on this video finally released by BP this week:
These estimates sound reasonable since BP’s Thunder Horse deepwater wells flowed upwards of 40,000 to 50,000 barrels per day under controlled conditions when they came on. As you can tell from the production chart below:
We talked about the well schematic on our Thursday post and I have received a request to post it, so here it is. It’s more of a cartoon image, not giving the exact depths of of the 7″ to 9 7/8″ crossover in long string, but gives a pretty good picture of what pipe is in the hole:
I’ll be talking about the insertion tube strategy later today.
