Underwriting the liabilities buyers miss in energy M&A
Low-producing California wells now carry plugging, assurance and transfer risk that standard PV-10 misses. I quantify it at the well level, before the deal closes.

01 — THE QUESTION
Who pays for the hole in the ground when production ends — the operator that earned from the well, the buyer that acquired it, or the public after the responsible company can no longer pay?
California has moved toward an answer. AB 1866 requires operators with idle wells to pay escalating annual fees or submit approved idle-well management plans. AB 1167 requires full-cost financial assurance for covered transfers of low-producing wells.
But rules are only enforceable when the liability can be measured. Company-level asset-retirement obligations do not tell the public whether each well is fully secured, how its closure estimate was calculated, or whether a transfer moved the obligation to a financially weaker operator.
The missing infrastructure is not another promise to clean up later. It is a verified, well-level map connecting each asset to its operator, operating status, transfer history, financial assurance, closure estimate, and compliance record.
02 — FROM LIABILITY TO INTELLIGENCE
- The liability outlives production
- A well may stop producing long before the obligation to plug it, remove equipment, monitor leakage, and restore the site disappears.
- Weak transfers move the risk
- An aging asset can pass from a well-capitalized producer to a smaller buyer whose balance sheet cannot absorb the eventual closure cost.
- Company accounts do not map the wells
- Asset-retirement obligations disclosed at company level do not show whether each California well is fully secured, who carries the obligation, or how risk changed after a transfer.
- Reuse is selective, not automatic
- Geothermal energy, carbon storage, lithium or brine projects may fit particular wells. Where they do not, reuse cannot substitute for timely plugging and restoration.
My thesis proposes a practical architecture: full-cost financial assurance adjusted for default risk; an industry-funded reserve for wells with no viable responsible party; independent verification; and public, well-level disclosure that makes liability visible before a transaction fails.
The same data can support a more constructive decision. Some wells may be candidates for geothermal energy, carbon storage, lithium or brine projects, subject to geology, engineering, permits, monitoring, and long-term liability. Others should be plugged, remediated, and returned to safe use. The purpose of the map is to distinguish between them — not to confuse speculative reuse with closure.
