Long-duration P&A assurance, built for how obligations actually work
OneNexus is a financial assurance platform built for energy operators facing growing decommissioning liabilities. WellSecure™ delivers an asset-based surety solution that eliminates collateral and letter-of-credit requirements — designed to satisfy regulatory obligations while protecting operators, investors, and landowners across the full life of the asset.
Why structure matters for long-duration obligations
Most financial assurance instruments were designed for short-duration or contingent risks. P&A obligations are neither. They are inevitable, long-dated, and often cross multiple ownership cycles. The assurance behind them should be built accordingly.
