WELL INTERVENTION DRILLING & COMPLETIONS UNCONVENTIONAL RESOURCES RESERVOIR OPTIMIZATION Two-Stage Cementing of Intermediate Casing Port Collar, LONGCAP , and Combo Tool Location: New Mexico CHALLENGE: An operator’s drilling program in New Mexico included wells with challenging cement operations. The weak, naturally fractured, and karsted formation surrounding the middle section of the intermediate casing could not support a primary cement job to surface regardless of the amount of excess cement pumped. The operator required a two-stage cement job to get the cement to surface. SOLUTION: Using caliper log results, TAM’s Port Collar (PC) and Casing Annulus Packer (CAP) were spaced out in competent formation 50 ft. above the problem zone. The first stage cement was displaced to the CAP
