Geologic Energy Management Division

​​​​​​​​The California Geologic Energy Management Division (CalGEM) prioritizes protecting public health, safety, and the environment in its oversight of the oil, natural gas, and geothermal industries, while working to help California achieve its climate change and clean energy goals. To do that, CalGEM uses science and sound engineering practices to regulate the drilling, operation, and permanent closure of energy resource wells.​




​​​​Idle Well Program​​​​Idle Well ProgramMandates for idle oil and gas wells include a compliance schedule to test for leaks and to plug and abandon (permanently seal) wells; engineering analyses for wells not in use 15 or more years; and enhanced idle well management plans.
