California Operators Face New Regulations and Large Fines


New California Department of Conservation Geologic Energy Management Division (CalGEM) underground injection control (UIC) compliance regulations, effective April 1, 2019, impact ~55,000 enhanced recovery and water disposal wells in California. Key elements of this new regulation include:

  • Stronger testing requirements to identify potential leaks
  • Increased data requirements to ensure proposed projects are fully evaluated
  • Continuous pressure monitoring and recording requirements
  • Requirements to automatically cease injection when there is a risk to safety or environment
  • Requirements to disclose chemical additives for injection wells close to water supply wells

Operators must fully implement a continuous monitoring system no later than April 1, 2021. Fines for non-compliance are up to $25,000 per day per inciden

Wellaware’s Calgem Division-approved Monitoring and Data Collection Service Keeps You in Compliance

WellAware’s Continuous Monitoring service installs in minutes and helps operators achieve compliance so they can eliminate manual data collection, avoid potential fines and failures.



Automated reports delivered on a set schedule, contain injection values, flow rates, maximum pressures, and alarm conditions.


Continuous monitoring of measurements every 5 minutes allows Operators to comply with CalGEM requirements.
