Bracewell has expanded its energy team with the addition of Bryan Clark, who returned to private practice after working in the in-house legal department at Dallas-based Pioneer Natural Resources, which was acquired by Exxon Mobil Corp. in a $65 billion deal in 2024.

Clark, based in Dallas, joined Bracewell on Monday as a partner in the oil and gas and energy transition practice groups. At Pioneer, he held a number of positions in the legal department, most recently managing associate general counsel. He served for more than a decade as the primary midstream counsel at Pioneer, and as lead counsel on energy transition matters including wind and solar development.
