​Well Maintenance and Cleanout History

​​​​​​​​​​​​Within 60 days of completing an operation on a well that involves emplacing fluid containing acid in the well or involves application of pressure to the formation that exceeds formation pore pressure, but IS NOT a well stimulation treatment, an operator is required to submit information about the operation to the Geologic Energy Management Division (CalGEM)​.


Well Maintenance forms must be submitted through the operator-access-only WellSTAR electronic database.

As of December 17, 2019, well maintenance operational data can be viewed in WellSTAR.

​Additionally, all ​Well Maintenance Determination Requests and Aggregate Well Maintenance plans must be submitted though the operator-access-only​ WellSTAR  ​​​Plan Submission form.
