Diamondback Sees No ‘Clear Signal’ to Boost Permian Output Diamondback Energy Inc. CEO Travis Stice said until there’s a “clear signal” to increase oil output, there are no plans to expand volumes this year in the Permian Basin. Stice and his management team discussed first quarter performance and the outlook for the oil and gas market during a conference call. The CEO pointed to the bump in global oil output underway by the Organization of the Petroleum Exporting Countries and its allies, better known as OPEC-plus. That’s reason enough to remain cautious, he said. “Even though oil demand has shown signs of recovery from the depths of the global pandemic, oil supply is still purposely being withheld from the market primarily through the actions of OPEC-plus,” Stice said. “As a result, we continue to believe we do not need production growth and we’ll hold our pro forma fourth quarter 2020 oil production flat through 2021.”
