Apache Corp. revamped its organizational structure on March 4, which included the promotion of both Clay Bretches and David Pursell.

As part of a strategic redesign undertaken in October, Apache has simplified its organizational structure to three teams consisting of operations, development and exploration.

Bretches, its current pipeline and transportation head, will lead the operations team. Meanwhile, Pursell, in charge of planning and reserves at Apache, was named to lead the development team. 

Apache said a head for its exploration team will be named after an ongoing search.

The Houston-based oil and gas company last week reported its fourth-quarter results, which included a more than $1 billion write down on its Alpine High assets in the Permian Basin. Overall, though, it reported a surprise adjusted profit then, benefiting from higher output at its shale assets in the Permian.
