In September, the world’s largest oil producer and producer of petrochemicals, Chevron, announced it was opening two new high-paying jobs in the US, bringing the total to four.

The job openings, which will open this spring, are expected to pay up to $90,000 per year. 

The move is aimed at helping Chevron to fill the demand for the company’s petrochemical products as it battles the rising cost of gasoline and oil. 

A spokesperson for Chevron said that the two new jobs will open in the Houston area, where the company has a production facility and where the oil production capacity is high. 

“Chevron welcomes a high-tech workforce with a passion for service, with a strong track record of success in the fields of petrodynamics and petrofuels, including the development of the world first hydrocarbon fuel that delivers cleaner and more sustainable fuels to the global marketplace,” the spokesperson told Business Insider. 

Two of the new positions will start as early as this summer, and the company is still evaluating which one to keep open. 

One of the jobs will be at the Houston-area Chevron refinery, which has a capacity of 8,500 barrels of oil per day.

The other job will be in a facility in Oklahoma City. 

Chevashop has been ramping up production of its petro-chemicals products, particularly for electric cars.

Last year, Chevron added two new rigs to its fleet of 1,600 electric-car-powered drilling rigs in the United States, including one in Oklahoma, according to Bloomberg. 

This is the first time in Chevron’s history that two of its two new petrojobs have opened in the same city, and it’s also the first such move in the state. 

When Chevron first announced the new jobs in September, it said that “there is a strong and growing demand for this highly skilled and driven workforce,” according to The Wall Street Journal. 

As of April 2017, there were 3,788 jobs at Chevron in the U.S. in oil and gas production, refining, and services, according the company. 

 Chevy’s announcement comes as the industry continues to fight against rising costs, as well as the increasing cost of driving fuel.

Last week, the electric car manufacturer Tesla announced a plan to hire 1,000 electric-vehicle drivers in the coming year.
