BP's Deepwater Horizon well is consistent. During drilling it lost mud into the surrounding rock formation. That's now oil. Reuters reported National Incident Commander Thad Allen said:
BP engineers and government scientists were concerned the cement may have trapped up to 1,000 barrels of oil in the space between the well pipe and the surrounding rock layers.The trick is to cement the well bottom without another blowout. Reuters stated:
They want to make sure pumping in mud and cement through the relief well will not force that oil up, where it could leak into the sea.
The well has at least three ways to blow. One is up the relief well shaft. Two is out the side of the existing well. Three is at the cemented top. There could conceivably be a combination of the above possibilities.
Yesterday I noted how badly BP wants an unruptured blow out preventer. Thad Allen stated this at the end of today's press briefing.
They want to make sure pumping in mud and cement through the relief well will not force that oil up where it could.... damage a failed blowout preventer central to various investigations of the April 20 blowout.BP's risk management response continues. Ken Feinberg and ExxonMobil came to BP's rescue.
