A drilling crew spent Wednesday working to pump a concrete and mud mixture into an oil well, that began spewing natural gas at 3 a.m.
The oil field is at Hermosa and Malaga Roads.
The oil field crew closed a blowout protection valve and stopped 95% of the leak. They were drilling horizontally, hoping to fill the hole with the mixture.
Five homes in the area were evacuated.
"Natural gas is lighter than air, and we have evacuated some farmhouses as a precaution," said Derek Tisinger, Kern County Fire Department.
At one point, gas was roaring out of the hole at such a high rate, it sounded like a jet engine.
