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.

Project Overview

The Kikeh field is located 120 km northwest of the island of Labuan at approximately 1300-m water depth. The field was developed using a standalone facility, with hydrocarbons being produced from both subsea and dry-tree wells from a spar/DTU facility.
