Redefining Well Abandonment Strategy: Tipping the Scale Towards Greater Cost and Operational Efficiency Through a Novel Multi-Layer Steel Barriers Cement Bond Logging
Abstract:Abandoning a producer or injector well post production decline and pressure depletion after all intervention efforts to revive the well productivity have been exhausted is gaining momentum in recent years by most of major operators. Huge number of candidates to be abandoned fall under legacy wells category with incomplete drilling history and cement integrity records which warrant new logging run to be conducted for cement bond evaluation at the expense of additional cost and rig time. Conventional cement bond… Show more
