Oilfield services major Halliburton Co. cut more than 600 positions from facilities in Texas and Oklahoma on April 6 as the company continues to adjust its business operations around a work slowdown resulting from the coronavirus pandemic and the Russia-Saudi production war.

"Halliburton confirms we are significantly reducing our workforce. This was a difficult decision, but is a necessary action as we work to successfully adapt to challenging market conditions," Senior Director of Global Communications and Marketing Emily Mir said in an April 7 email.

In separate letters filed April 6 with the Texas Workforce Commission, Halliburton's human resources manager, Darrik Lasater, said the company would immediately and permanently lay off 234 employees at its Odessa facility and 41 employees at its facility in Brownfield.

Fracking and cementing jobs were the hardest hit at the two facilities, while services and truck driver jobs were also lost as the company deals with a sharp decline in work activity.

The latest Texas job cuts follow the implementation in March of a mandatory 60-day furlough for 3,500 workers at Halliburton's Houston facility. On March 23, employees began working a one-week-on, one-week-off schedule. Workers receive pay only for the on weeks, while benefits continue through the furlough period.

In addition to the layoffs in Texas, Halliburton notified Employer Workforce Services and State Rapid Response Coordinator Bill Hancock at the Oklahoma Office of Workforce Development that beginning around April 6, 350 jobs would be cut at the company's facility in Duncan, Okla.

While the job cuts will be permanent, the Duncan facility will remain open, Halliburton said.

In December 2019, the company shuttered operations at its office in El Reno, Okla., putting more than 800 people out of work. The facility was the home of Halliburton's Remote Operations Command and Control Center used to monitor its well completion operations across various shale plays within a Mid-Continent region that included all of Oklahoma and parts of Texas, Kansas and Colorado.

The job cuts are among a series of actions the company is taking as a result of "unforeseeable business circumstances including the unprecedented decline in oil and gas commodity pricing due to OPEC+ policy and the worldwide business disruptions on our customers and suppliers due to the unprecedented impact of coronavirus," Mir said in the April 7 email.

As part of the companywide measures, executive salaries are being reduced, Mir said. Mir failed to provide details on the salary reductions.
