A Halliburton Co. unit will plead guilty to destroying tests on cement work done on a BP Plc-owned oil well that exploded and caused the 2010 Gulf of Mexico oil spill, federal prosecutors said.

Officials of Halliburton Energy Services Inc., which worked on BP’s Macondo well, will plead guilty on the unit’s behalf to one count of destroying evidence for failing to preserve computer models examining the final cement job on the well after the April 2010 explosion that killed 11 workers and sent millions of barrels of oil pouring into the gulf, the U.S. Justice Department said yesterday in a statement.

“Efforts to forensically recover the original destroyed 3D computer simulations” for a liability trial over the spill earlier this year were unsuccessful, federal officials said.

The Halliburton unit will plead guilty to one misdemeanor violation “associated with the deletion of records created after the Macondo well incident,” pay the statutory maximum fine of $200,000 and accept a term of three years’ probation, the company said in a statement. The plea is subject to court approval.
