Wall Street JournalWASHINGTON (Dow Jones)--An oil-drilling expert will tell a Senate panel Tuesday that human error may explain a deadly oil-rig explosion in the Gulf of Mexico that for weeks has been leaking thousands of barrels of oil a day into the sea.
F.E. Beck, a petroleum-engineering professor at Texas A & M University, will tell the U.S. Senate Energy and Natural Resources Committee that in spite of multiple safety measures used in offshore drilling, "there remains the potential for human error to create conditions by which barriers are subjected to loads for which they were not designed."
The testimony was reviewed by Dow Jones Newswires.
BP Plc (BP) was leasing the oil rig from Transocean Ltd. (RIG) when the rig exploded on April 20. The explosion came shortly after Halliburton Corp. (HAL) had finished cementing a pipe into place.
Bud Danenberger, the former chief of the offshore regulatory program at the Interior Department's Minerals Management Service, will tell the panel that from 1992 through 2006, 18 of 39 blowouts--in which gas rushes up through the pipelines--involved cementing operations. Without offering any conclusions about the cause of the Deepwater Horizon explosion, he will say that an industry standard should be developed to address cementing problems, how they occur and what action should be taken when they do occur.
