California regulators on Tuesday requested more technical information from Chevron Corp. on the Cymric oilfield cyclic steam operations in Kern County, which is being investigated for a leaking abandoned well.

The water and oil spill is in California’s fourth largest producing oilfield, which includes around 3,560 active wells. The California Department of Conservation's Division of Oil, Gas and Geothermal Resources (DOGGR) estimates the well has leaked around 24,000 barrels since it was reported in May.

Chevron had 350 active cyclic steam injection wells in Cymric. Since the state’s underground injection control (UIC) regulations took effect in April, there have been at least eight surface expressions "intermittently or continuously active.”

Chevron spokesperson  Veronica Flores-Paniagua said the goal is to prevent seeps "consistent with DOGGR's updated UIC regulations," and it is working with the state to address any seeps that occur.

The seeps "are fully contained, and do not pose a threat to drinking water. Appropriate actions have been taken to protect the health and safety of our personnel, communities and the environment."

Chevron continues to provide the state with a "broad scope of historical and current technical information,” Flores-Paniagua said. "We have a dedicated team working to develop a holistic approach to prevent and manage seeps across our Cymric thermal diatomite operations.”
