After the deployment of the CST, a 27 m³ balanced cement plug with 1.90 SG cement was set above the CST, followed by a 5-step hesitation squeeze job. The operator waited 30 hours for the cement to harden.
Cement was tagged at 2,194 m, and soft cement was drilled to 2,229 m using a PDC bit. Competent cement was then drilled to 2,311 m, indicating the loss zone was deeper than initially expected and that the CST had moved 75 m down while still effectively directing the cement into the loss zone.
A successful FIT was performed after drilling out the cement plug, and the section was drilled to TD at 2,830 m with no further losses.
