Decommissioning and Abandonment
Is there a value proposition for decommissioning?
Our industry is governed by rules that require cleanup and closure of oil and gas facilities after they cease to produce. Unlike a capital project, decommissioning is not something that you can choose to do or not to do. The choices for a decommissioning project are really when and how, with a resulting “how much?” The “when” typically defaults to “not now,” representing a belief that deferral results in the lowest cost outcome. Is “not now” really the value proposition for decommissioning?
I assert that the value proposition for decommissioning is really one of value retention through proactive late-life planning. Perhaps a suitable time frame to invoke a value metric is when the remaining hydrocarbon value equals the estimated decommissioning costs. Good planning decisions would then balance capturing the remaining hydrocarbons with delivering a cost-effective decommissioning project. The goal then becomes maintaining this value equilibrium; far too often, it is only the remaining hydrocarbons or a deferral that receives attention. Governance for late-life asset and project planning decisions could then be tested against maintaining this value equilibrium. For example, the foresight to select a cessation-of-production date to capture a downcycle decommissioning market could capture value that would have been lost in a blind drive to deferral. Like a capital project, there are a number of early planning decommissioning activities that can be deployed to maintain that value equilibrium. Let us consider this value metric and approach for future decommissioning projects.
