"The pressure buildup we're seeing is consistent with the modeling we did around reservoir depletion and full integrity," Wells said.

“我们正在看到的压力增加是与我们在油藏枯竭和完全完整周围的模型一致的。”威尔斯说。

During the pumping and displacement of the heavyweight spacer used to displace the mud, a breach in pressure integrity resulted in the undetected loss of drilling mud into the probably uncemented well-bore.

FORBES: BP Full Of Fault For Gulf Spill But Obama Guilty Of Propagating Economic Disaster

If pressure bleeds off there is clearly a problem with the pressure integrity of the shoe, However, industry practice dictates that a positive test, that is no pressure drop, is not diagnostic, simply because the reservoir pressure is sufficient to retain the pressure being applied.

"This has really helped us understand how long under submerged pressure the recorder is able to maintain its integrity, so you don't have corrosion or sea water entering into it, " he told CNN.
