In an effort to revitalize an aging production field, Chevron tasked Keystone with developing a comprehensive design that could efficiently and effectively monetize reserves and production in the East Flank of bay Marchand. In phase 1 of the redevelopment project, Keystone optimized the well targeting, workovers and construction of new infrastructure. Phase 2 focused on further evaluation of both Greenfield and Brownfield project options developed in Phase 1 to handle production from approximately 50 new well sites. Keystone was directly involved in the creation of multiple concepts (Greenfield, Brownfield, and hybrid) that satisfied the overall project objectives. With collaboration between multiple Keystone offices, this Major Capital Project for Chevron highlighted our team’s capabilities. The level of detail required for cost estimates and schedules for each concept necessitated the creation of new estimating tools and a plethora of valuable data for future offshore projects.
