This paper discusses the systematic approach adopted by BP Exploration to achieve its goal of safely abandoning the wells on a major North Sea platform. Having determined the abandonment methodology, an integrated team, comprising oil company engineers and key service company personnel developed processes and procedures to reach the objective. These included advances in coiled tubing rig-up procedures and the use of Technical Limit to capture learning. This approach facilitated the timely and cost effective abandonment of 24 wells in a safe and environmentally friendly manner and in achieving world-class performance.
