Investment-Grade Methane Abatement & Liability Resolution​

 

Helping North American oil and gas operators permanently retire marginal and inactive well liabilities using verified carbon finance.

Theaus CH₄ provides a capital solution for oil and gas companies holding marginal and inactive wells with long-dated environmental liabilities. By permanently eliminating methane emissions through regulator-approved well abandonment, we convert unavoidable liabilities into durable, investment-grade climate assets.

​

The Challenge

Marginal and inactive wells across North America carry unavoidable abandonment obligations, yet capital to execute closure is often constrained. These assets continue to emit methane, compounding environmental liability and balance-sheet risk while public funding programs remain oversubscribed and slow.

Key challenges include long-dated closure obligations, non-revenue capital requirements, and persistent methane emissions from aging infrastructure.

​

The Solution

Theaus CH₄ enables operators to permanently abandon marginal and inactive wells, eliminate methane emissions at the source, and retire long-term environmental liabilities. Commercial alignment is determined on a project-by-project basis and is discussed directly with operators following eligibility and assurance screening. 

Using verified carbon mechanisms, we enable accelerated abandonment execution and liability retirement without requiring operators to deploy internal capex. This accelerates remediation timelines while creating defensible, investment-grade climate value suitable for institutional scrutiny.

​

Our mission is to deliver verified methane emission abatement through measured, assurance-aligned abandonment, while advancing environmental stewardship and long-term risk reduction for communities and ecosystems.
