Well Finder

​​​​​​​​The Geologic Energy Management Division's (CalGEM) online mapping application Well Finder presents California’s oil and gas industry information from the geographic perspective. You can find and locate oil and gas wells and other types of related facilities throughout the state. Search by address, latitude/longitude, unique well number (also known as “API”), Public Land Survey System (PLSS) township/range/section, or by oil and gas field names. Dig deeper into individual well records. Explore where permits have been issued for oil and gas operations. Investigate wells by their type of use, such as oil and gas producers versus injectors.

Well Finder is a tool CalGEM provides to improve informational transparency. Readily available data contributes to better health and environmental safeguards--fundamentals of the CalGEM mission. Data can help inform California's efforts to achieve the twin goals of mitigating climate change and a net-zero footprint.

Well Finder interfaces with CalGEM’s online Well Statewide Tracking and Reporting System (WellSTAR) database and is updated nightly.
