BP has accepted some of the blame for the deadly rig disaster that led to the worst oil spill in United States history, according to a new report.
An internal investigation reveals that the oil giant’s own engineers misread data that contributed to the explosion aboard the Deepwater Horizon, a source familiar with BP’s probe told Bloomberg News.
As a result of the misinterpreted data on April 20, rig workers began replacing drilling fluid in the doomed well with seawater, which was too light to prevent natural gas from leaking into the well.

This led to the explosion, the report says, which killed 11 workers and ultimately spewed nearly 5 million barrels of oil into the Gulf of Mexico.
The internal probe is one of many looking into the causes for the disaster. Other companies, including Transocean, which owned the oil rig, and Halliburton, which was working on the well prior to the blast, have also come under scrutiny. However, both companies have pointed fingers back at BP.
