Oil, Gas & Geothermal- Field Rules

Pursuant to California Code of Regulations (CCR) Title 14, Division 2, Chapter 4, Section 1722 (k), the State Oil and Gas Supervisor may establish Field Rules for any oil and gas pool or zone in a field when sufficient geologic and engineering data is available from previous drilling operations. Field Rules supplement more broadly applicable statutory and regulatory requirements. Each Field Rule is specific to a field, and in many cases, specific to Areas and Zones or Pools within a field.

The Division has established Field Rules for those fields where geologic and engineering information is available to accurately describe subsurface conditions. These Field Rules identify downhole conditions and well construction information that oil and gas operators should consider when drilling and completing onshore oil and gas wells.

Field Rules are continually reviewed and updated as ongoing field operations generate new technical information, including geologic data. Operators planning to drill should review the most recent field rule versions before drilling.

  • To view and download an Excel file of the Field Rules Index, click here.

  • To inquire about Field Rules, contact the Division District office where the field is located. For a list of district offices, click here.
