Digital oil field (DOF) in the upstream industry has gained momentum in the last few years and has transformed from being solely a vision to actual projects that have measurable value. The ultimate goal in DOF projects is an integrated approach toward decision making and control of asset management in relevant time. This paper describes the successful methodology adopted for implementing the i-field™ program (i-field is a trademark of Chevron Corporation) in Agbami-namely, identification, prioritization, and implementation of relevant workflows.The Agbami field, located in deepwater offshore Nigeria, is a subsea development that incorporates crestal gas and peripheral water injection. It is located in approximately 1500 m of water depth and consists of a 38-well development program to be implemented in three phases. The well completion incorporates intelligent well completions (IWCs)-downhole flowmeters, pressure and temperature gauges, and interval-control valves (ICVs). These downhole accessories are managed using electric and hydraulic controls/instrumentation, with subsurface, subsea, and topside data acquired and transmitted to a central data historian on the floating production, storage, and offloading (FPSO) unit in relevant time. The implementation of a robust architecture for a data-and informationmanagement system involving acquisition, processing, storage, and replication (from offshore to onshore) is conceived to be the foundation upon which asset-management workflows are implemented.The expected benefits from implementing the i-field program in Agbami include reduction in lost production opportunity (LPO) through proactive asset management, better long-term reservoir management through time-line management of injection-and production-rate balancing, increased efficiency and reliability through guided workflows, improved ultimate recovery, and better overall performance from standardization of base business work processes. The real value of implementing i-field initiatives in Agbami lies not only in the return on investment but also in providing a benchmark for capturing the value of other assets. Based on field experience, this paper discusses the approach toward value realization of the i-field system, including change-management strategy for end-user acceptance. Critical success factors and lessons learned during deployment are also presented.

SPE 127691The Agbami i-field™ opportunity was to design and implement by first oil, an integrated, multi-disciplinary series of work processes, tools, and technologies that will enable the asset team to make better and timely decisions, thereby sustaining the production plateau and enhancing the value of the Agbami asset. This goal was achieved in July 2008, when Agbami achieved first oil and several priority workflows were implemented to support start-up and ramp-up phases 1 . Subsequently, several other workflows were implemented to enable and support well-reliability monitoring, reservoir management, and production optimization work processes.This paper is a sequel to the earlier work 1 describing the i-field™ initiatives in Agbami.
