Casing/ liner drilling has been successfully utilized around the world to solve localized drilling challenges. The applications have generally been aimed at minimizing unscheduled events related to wellbore instability while drilling through depleted reservoirs. However, recent technological advances are driving casing/ liner drilling from a niche market into the mainstream drilling environment. Escalating deepwater costs and the need to further reduce onshore drilling expenses in low-cost fields continue to push the technology forward. Improved connections and tubulars, as well as advances in rig technology and pipe handling, have enabled operators to consider drilling with casing/ liner as a viable cost-cutting option on many new wells.
