Parker Drilling Company, a global provider of drilling services and equipment, recently announced that it intends to relocate its headquarters to Houston. The move will affect 116 employees in the company's Tulsa, Okla., home office. Some of the Tulsa employees will be asked to relocate to Houston, where the company currently maintains a regional office for its Gulf of Mexico (GOM) drilling operations. Employees who are not requested to relocate to Houston or who decide to not move will be offered a severance package. The company plans to make the move to Houston this summer leaving a small regional office in Tulsa.
