AbstractFull field optimisation is a key element of BP's FIELD OF THE FUTURE technology strategy aimed at delivering a capability for remote operation and remote performance management of BP's upstream producing assets. Field of today, Valhall, is a BP operated asset in the Norwegian sector of the North Sea with a track record of applying model-based optimisation technology to support production delivery.Optimisation of an upstream producing asset is a crossdisciplinary process requiring close team-working and ownership of optimiser advice from all engineering disciplines, reservoir management, well performance and facilities, through to operations and commercial staff. Working with the FIELD OF THE FUTURE business process transformation team, the field trial focused on all aspects of the people, process and technology required to deliver sustainable value. The paper discusses key conclusions from the field trial and also how the learnings will influence the way forward for this technology in BP.
Managing and optimising BP's integrated operations presents an increasingly complex challenge with the move to deeperwater production and the use of sub-sea processing and multiphase tiebacks from satellite fields. Production system optimisation requires the simultaneous assessment of flow stability and well draw-down maximisation whilst honouring the constraints of reserves recovery though the reservoir management depletion strategy.BP has a strong track record of applying fundamental mechanistic models to support operational decision making and optimisation. When reconciled with real-time and historical production data, physical models of a production system increase operators understanding of the system and allow changes to operating strategy to be made with increased confidence. Moreover, inferred model parameters can be use to track the health and efficiency of component parts of the system feeding an enhanced predictive maintenance capability.Mechanistic models of a production system are themselves complex and challenging to use and maintain. Normally their use is restricted to modelling experts primarily for design purposes or to support troubleshooting following a production upset condition. Delivering such models for use within an operational environment requires a large number of issues to be addressed, in particular how such models can be applied quickly and robustly with assurance, and how they are scoped and maintained.This paper outlines how BP E&P is tackling these issues through the Field of the Future TM Model Based Operational Support programme as the capability is deployed further within the Upstream organisation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
