Layoffs are on the horizon for hundreds of oil and gas workers in Texas in the New Year.

In recent months, Pioneer Natural Resources, Covia, Petrobras and Siemens have all announced staff reductions at Texas facilities, according to industry website Rigzone.

Details surrounding the job cuts, sent to the Texas Workforce Commission and reported by Rigzone, included: Pioneer Sands, acquired by Pioneer Natural Resources in 2012, will shut down operations at its plant in Brady, Texas, which currently employs 219 employees.

Employment separations will occur in phases beginning January 14, 2019 through the end of 2019. Covia Holdings is ceasing operations at its Voca, Texas, facility on January 31, 2019. A total of 93 employees will be affected.

The company said a small number of employees may be retained beyond January 31 to wind down operations, though all employees are expected to be terminated within 90 days following the closure date, except for one employee who has been reassigned.

Petrobras America is downsizing its facility in Houston, Texas, beginning February 28, 2019 as a direct result of the company selling all of its assets in the Gulf of Mexico.

Layoffs of more than 50 employees (more than 33 percent of the company’s workforce) will occur from February 28 through October 31, 2019.

Siemens is closing its Houston Service Center and will transfer all manufacturing activities to other Siemens facilities due to market conditions and network overcapacity. This will result in the elimination of 17 positions on January 13, 2019.
