The presentation reviews the challenges to creating sustainability in well decommissioning. Starting with asset economics, an overview of well decommissioning subsurface and well operation fundamentals. Then it pivots to enablement, discussing the design of disruptive operation structures and development of sustainable well decommissioning operations which reduce environmental and financial risk. The considerations for design for decommissioning and carbon capture re-purposing are discussed, to assess the governance and structures needed to create value from the wellbore.
