Initial Killing Process Improvement for Plug and Abandonment Job at Duri Steam Flood Environment

Abstract

Every year, Maliha Minyak Indonesia (MMI) should perform Plug and Abandonment (P&A) in the uneconomic existing wells. One of the wildly unpredictable procedures that take longer duration and budget is the Initial Killing procedure. From 159 well executions, initial killing takes an average of 15 hours, while the target stated in P&A programs is only 4 hours. The research focuses on seeking the best alternatives to improve the initial killing process in the Plug and Abandonment well. It starts to correlate the contributing factors then find the root causes of the prolonged initial killing process. The root cause is analyzed using the Current Reality Tree based on interviews and observation. The data to support the research are from P&A job execution in 2019 - 2020. The best alternative is to perform an offline initial killing process by pumping cement. This solution has been implemented in 3 wells and contributes to rig cost reduction, kill fluid cost elimination, and cycle time acceleration in USD48,031.
