Abstract:Recurring safety incidents due to unexpected gas leaks from downhole and sustained annulus pressure issue have become major catastrophic events which warrant an integrated solution to determine the leakage pathways, the root causes and the remedial job required. The unexpected gas migration has impacted the production leading to permanent well abandonment leaving a significant gap to meet the production target. Hence, a proactive diagnostic and remedial solution are required in place as an agile response to th… Show more
