The troubling year for oil and gas companies continues as three more oilfield services companies announced they will be laying off workers in Texas – nearly 400 positions total.

In three separate letters to the Texas Workforce Commission (TWC), Trelleborg Offshore, National Oilwell Varco and Cameron International announced they would be cutting 200, 120 and 75 jobs respectively.

Trelleborg Offshore, which offers engineered polymer solutions, is laying off about 200 of its 416 employees and temporary workers at offices on Rankin Road and Hardy Road in Houston. The first notice of termination occurred Nov. 4, and subsequent terminations will occur over the next few months with final terminations expected to occur in January 2016, the letter said.

A spokesperson for Trelleborg told Rigzone the company has “released 85 employees in Houston whose positions are primarily from the production operations unit for Drill Riser Buoyancy manufacturing.” The spokesperson also said future business and projects have been deferred one to three years due to the oil price and low volumes of current business and that small batch sizes did not make it economical to retain the large work force they had.

National Oilwell Varco, a company that supplies oilfield equipment, is permanently closing its support facility in San Angelo, resulting in the termination of 120 employees. The layoffs are expected to be completed between January 15 and January 29, 2016, according to the letter to the TWC.

In an emailed statement to Rigzone, a National Oilwell Varco spokesperson said the company will be consolidating the San Angelo facility into other existing manufacturing facilities and that the consolidation is “consistent with long-term plans to optimize its global footprint.”

Oilfield services provider Cameron International is laying off 75 employees at its Houston facility on Thomas Road, citing “current declining business conditions” in the letter to the TWC. The layoffs could begin as early as January 11, 2016. The company will offer severance benefits and transition programs (including outplacement services) to affected employees.

Request for response from Cameron International was not received as of press time.
