Case Study NPT Spending Stops with Open Hole Liner (OHL) Challenge The 9-5/8 in. casing was set high due to unforeseen pore pressure/frac pressure regression. While an additional casing string was needed below the shoe; it needed to accommodate a 7 in. production string into the reservoir. Cement squeezes to regain formation integrity were unsuccessful; alternatives such as sidetracking or pulling/re-running the 9-5/8 in. string were going to be time-consuming and expensive. Added Value The Operator reduced potential NPT by not spending rig time on squeezing. The SET ® system successfully mitigated wellbore instability while achieving the goal of completing the well with a 7 in. production string. Thus costly sidetracking or re-running of casing was avoided.
