This session delves into the lifecycle of older oil and gas wells in the Anadarko Basin of Kansas and Oklahoma, highlighting their economic and environmental implications as they approach the end of their productive life. Experts will explore decline curve analysis (DCA) as a critical tool for forecasting well behavior and informing decisions on plugging and abandonment (P&A) or repurposing. Attendees will gain insights into how these efforts can mitigate methane emissions and the broader implications for greenhouse gas management.
