WATCH: Federal Report Says BP's Poor Management To Blame For Oil Spill

A federal investigation of last year's oil spill by a British Petroleum well in the Gulf of Mexico revealed much of the disaster could be attributed to poor management by the oil company and its contractors.

According to the Wall Street Journal, the report said BP focused more on cost-cutting than safety during the operation of the well, causing a lax atmosphere that culminated in last year's disaster. 

The report also said rushed construction methods by Transocean and Halliburton further exacerbated the situation.

Melissa Schwartz, spokeswoman for the Bureau of Ocean Energy Management, Regulation and Enforcement, said the report went through many drafts to make it accessible to the public, delaying its release.

"It was more complicated an investigation than anyone realized," she said.
