The project activity is plugging four orphan wells in Beaver, Canadian, and Nowata Counties. Each of the four wells in the project were documented as orphan wells by the Oklahoma Corporation Commission. The wells were leaking methane into the atmosphere. Additionally, these wells pose health and well-being risks to the landowners and threaten proximal natural resources. As of April 2023, there were over 21,000 documented orphan wells in the state of Oklahoma. Over the past decade, the Oklahoma State Funds Plugging Program has plugged an average of ~140 orphan wells per year. At this rate, it would take the better part of the next century to plug Oklahoma's orphan wells. Even with additional federal funds, state-allocated resources are still not available to plug this inventory in any reasonable timeframe. Rebellion Energy Solutions, the project developer, has taken responsibility for proper plugging and remediation of these wells, and 17 additional wells in this project timeline that are outside of the scope of issuance, resulting in additional atmospheric benefits outside the scope of the carbon market. Project activities include the quantification of leaking methane from orphan oil and gas wells and the subsequent mitigation of leaking methane via permanent plugging of wellbores. Methane abatement is confirmed post-plugging. In addition, as a voluntary benefit, land restoration was conducted in and around the well sites as allowed in cooperation with landowners and included native state restoration. The purpose of this project is to offset the fugitive methane emissions that were and would have been generated by the wells in question in the scenario that wells were not plugged.
Rebellion applies a Certainty Policy to forecast methane emissions from orphan wells like those in Heartland 3, using conservative exponential decline models to define terminal vintages and ensure credit issuance aligns with scientifically grounded expectations of emissions tapering. By integrating terminal decline rates and applying its certainty policy, Rebellion automatically retires credits once modeled emissions fall below the minimum credible threshold, ensuring that each vintage reflects only high-confidence, verifiable emissions. This approach supports a transparent, data-driven crediting framework where vintages are phased out in accordance with the natural decline of emissions, reinforcing environmental integrity and investor confidence through the certainty policy’s conservative guardrails.
