An operator working in Kenya was preparing to cement the 7-in. casing section of a new well. While running the casing however, the operator began to experience severe lost circulation issues, and had to reestablish circulation after each casing joint was run in-hole. This indicated to the operator that the fracture gradient (FG) was lower than previously thought—which was verified through subsequent analysis—and it became clear that the planned cement program would exceed the FG, leading to lost circulation and failed zonal isolation. With only two days until cementing was scheduled to begin, the operator asked Baker Hughes, a GE company (BHGE) for a re-designed cement program that would achieve the necessary zonal isolation and prevent losses.
