Figure 1—Photograph of Kikeh field surface layout showing the Seadrill West Menang semitender contracted for well workover in the left foreground, the Murphy Kikeh spar DTU in the right foreground, and the Kikeh FPSO in the background. A deepwater field located offshore Sabah, east Malaysia, features a spar dry-tree unit (DTU) and multiple subsea-hub tiebacks to a floating production, storage, and offloading vessel (FPSO). In early 2011, several of the wells began producing solid fines that affected production. It was decided that a long-term solution would be to recomplete the affected wells with enhanced downhole sand control on the lower completions. The short-term solution consisted of installing a topside sand-management system on the spar and sand-sparging equipment on the FPSO separators.
