California oil and gas producer Royale Energy Inc. said its first well drilled as part of a joint venture (JV) with California Resources Production Corp. (CRPC) has hit natural gas in the Rio Vista Field.

The company said Jan. 9 that production casing was set on the recently drilled RVGU #33-1 well in the field. Openhole logs indicate 174 net ft of probable gas zones and 37 net ft of possible gas zones. Plans are to conduct testing at the well within the next five to 10 days.

“We are excited that the first well drilled under the new Joint Venture with CRPC appears to be a strong gas well,” Royale Energy CEO Johnny Jordan said in the release. “This first well is a good indicator of the potential of the new prospects we have identified in the Rio Vista Field.”

The RVGU #33-1 is the first of 30 wells Royale intends to drill under its three-year JV arrangement with CRPC in the Rio Vista Field, which is California’s largest natural gas field, the company said.
