Many acres of land in the U.S., including valuable coastal areas, are underutilized due to the presence of active, idle, orphaned, or abandoned oil wells. However, these wells often require manageable remediation to enable development. In the hands of a professional environmental remediation expert, these properties offer opportunities to enhance housing and land values when properly addressed.
He is delivering a presentation at the 2026 Orphan, Idle & Marginal Wells California Conference on March 24-25, 2026. His presentation, “Acquiring and Developing Land with Abandoned Wells in California: Navigating Regulations, Risk, and Practice,” provides insight for landowners and developers to learn more about the support your environmental assessments should cover, including:
Navigating the regulatory, technical, and transactional complexities of acquiring and developing properties
Understanding CalGEM requirements
Local permitting expectations
Financial assurance obligations
Environmental liabilities
In Tim Rathmann’s upcoming article, he examines how to go about the process in California, including:
Regulatory framework and oversight: Development involving lands with oil wells is governed by CalGEM, which regulates well plugging, access, and redevelopment standards, including requirements for re-abandonment if projects limit well access. Local agencies add further restrictions, such as setbacks and grading controls.
Due diligence and site assessment: Locating and verifying wells involves using regulatory tools, historical records, and field surveys. Well integrity assessments include gas surveys, pressure tests, and soil or water sampling, ideally conducted before and during construction, and before obtaining permits and grading.
Financial, liability, and transactional considerations: Developers must clarify financial responsibility for well re-abandonment and address environmental liabilities like hydrocarbon contamination early to avoid delays. Real estate agreements should explicitly allocate responsibilities for well identification, plugging, cleanup, cost sharing, indemnification, and disclosures.
Re-abandonment process and collaboration: When wells no longer meet standards or access is obstructed, re-abandonment involves submitting notices via the regulatory system and engaging qualified professionals to perform plugging procedures with regulator coordination to ensure compliance and avoid delays.
