This paper presents an overview of how the Shell Group of Companies has implemented the Well, Reservoir and Facility Management (WRFM) methodology in its Upstream assets. It discusses the different parts of the WRFM Value Loop, and presents case histories and successes from within the Group.

Effective Well, Reservoir and Facility Management requires the integrated contributions of Petroleum Engineering, Production, Facilities and Process Engineering, and Well Services. The detailed WRFM plan defines the type and frequency of the surveillance and data acquisition activities that need to be carried out in order to optimise the production from the asset, and to manage the uncertainties that remain in the development of the asset. WRFM is a structured and integrated approach to data gathering and data management, modeling and interpretation, identification of production enhancement opportunities, and intervention to deliver the opportunities to maximise asset value. This process is represented as the WRFM Continuous Improvement loop, or Value Loop. WRFM targets are set on a yearly basis and progress is measured against the targets. Information and best practices are shared laterally and through the company's global WRFM team.

The various segments of the WRFM loop are presented below in detail, and are illustrated by appropriate case histories. Rigorous application of the WRFM methodology has resulted in considerable improvements in production gains and water injection performance.
