Warren Resources Inc., which said in September that it would close its offices in New York City and Roswell, NM, to cut costs amid the commodities downturn, said three of its top executives would leave the company as a result of those closures (see Shale Daily, Oct. 1). General CounselSaema Somalya, Vice President of Corporate DevelopmentJeffrey Keeler and Chief Accounting Officer Brian Gelman have chosen to leave the company as it shifts its headquarters from New York City to Denver. The New Mexico office, the company said, was closed Dec. 1, and the New York closure is on track for March 2016. Warren has appointed John R. Powers, formerly of Dune Energy Inc., to serve as its vice president of accounting. The company also recently hired James Watt as its CEO and Frank T. Smith Jr. as its CFO, both of whom had previously worked for Dune. Powers' appointment completes the company's finance management team (see Shale Daily, Nov. 30).
