Collapsible Landing Sub Deployed with Mechanical Inflow Test Packer Allows Liner Lap Testing and Shoe Track Drill Out in One Trip, Decreasing Costs and Increasing Reliability

Abstract: Liner lap testing operations in the gas fields have evolved to include shoe track drill out operations in the same trip. Typically, a drilling BHA is run and spaced below an inflow test packer to drill out the shoe track to 20ft above the shoe. A landing sub or no-go lands in the liner top at the predetermined bit depth to activate a test packer mechanically. This order of operation exposes the packer elements to debris circulated from drill out operations resulting in damage to the packer elements or incorrec… Show more
