During the P&A well decommissioning phase, conventional through-tubing barrier evaluation operations require removal of inner pipe (casing or tubing) to evaluate the B-annulus and assess well integrity. This traditional approach to barrier or cement evaluation may take several days per well, depending on the operational complexity—increasing rig time and costs.

Watch this World Oil webcast to learn how Epilogue dual-string barrier evaluation eliminates the need to remove the inner pipe, enabling you to evaluate both the A- and B-annulus in a single run to reduce rig days, costs, and overall carbon footprint.
