Drilling and Operating Oil and Gas Wells in California
All California oil and gas wells, onshore and offshore (within three nautical miles of the coastline), located on state and private lands are permitted, drilled, operated, and plugged and abandoned under requirements and procedures administered by the Department of Conservation’s Geologic Energy Management Division (CalGEM, formerly DOGGR).
Before CalGEM can approve a
Notice of Intention to Drill a New Well (PDF), every operator must designate an agent who resides in California and serves as the company contact for all correspondence, including well permits. An individual operator may appoint himself or herself as agent.
The Notice of Intention to Drill form must be filed, in duplicate, with the
appropriate CalGEM district office. CalGEM approval must be received before drilling can begin. An individual indemnity or cash bond must accompany every Notice of Intention to Drill, unless a blanket bond has been filed previously. Individual bond amounts are based on well depth.
An operator may request confidential status for exploratory wells and certain other wells where there may be extenuating circumstances. The request must be in writing and provide sufficient justification.
If you have any questions, please contact the
appropriate CalGEM district office.
