Geothermal Field Data Reporting Guide

​This guide includes instructions for reporting field data to the Department of Conservation's Geologic Energy Management Division (CalGEM, formerly DOGGR). Every geothermal company employee who is involved in collecting or reporting monthly production and injection data should be familiar with these instructions. Contact the appropriate CalGEM geothermal district office for assistance prior to submitting the first production and injection reports.

General Requirements

Monthly requirements
The Public Resources Code requires that geothermal operators file production and injection reports for all private, state, or federal wells producing or capable of producing or injecting geothermal fluids.

Data Accuracy 
Numerical data acquired by an operator must be submitted to DOGGR either as integers or as numbers accurate to a fixed number of places after the decimal point. Read the requirements for each data item.

Delinquent Reports 
Reports are delinquent if not submitted to CalGEM before the last day of the month following the month in which production or injection occurred.

Federal Requirements 
Wells on federal lands also require monthly production and injection reports. Contact the BLM-California for guidance.
