Provide Annular Isolation and Perform Off-Bottom Cementing Operations
WELL INTERVENTION DRILLING & COMPLETIONS UNCONVENTIONAL RESOURCES RESERVOIR OPTIMIZATION Provide Annular Isolation and Perform Off-Bottom Cementing Operations Pump Out SCC and TAMCAP Assembly Location: Queensland, Australia CHALLENGE: Many coal seam gas wells in Queensland run slotted casing in the production casing string. An off-bottom cement job is required to cement the casing to surface. Annular isolation is required to get good cement to surface and traditional stage tools require a dedicated drill-out trip to move the well to production. SOLUTION: The Pump Out Stage Cementing Collar (SCC) and Inflatable Casing Annulus Packer were placed directly above the slotted casing in the 7-in. production casing. Once on bottom, pressure was applied to inflate the TAMCAP and provide ann
