An online real-time production optimization and monitoring system for the Greater Ekofisk Area of Norway was installed in 2006. The system has evolved significantly since installation; changes driven by multi-disciplinary teams in coordination with the ConocoPhillips Production Optimization Centre (POC).The POC, Subsurface Production Delivery and Reservoir Optimization teams are tasked with assessing real time data from nominally 160 active producers and injectors in order to minimize losses and thereby maximize field production. This online system integrates data from the complete production system: reservoir to export meters. The system realises the importance of visualisation with respect to monitoring field performance, streamlined decisions, and reduced man hours mining data and analysis. The system allows real time monitoring of all wells and associated instrumentation parameters along with field three phase production allocated to the well level. The system alerts an engineer's attention when a well's performance is outside predefined tolerances thereby enabling continuous optimization of the combined field network. This paper demonstrates how the online system addresses the following challenges:• Real-time monitoring of separator loadings, production/injection well performance • Daily production/injection volume losses allocation • Quick screening and allocation issues • Generation of updated well models with the latest well test data for further analysis (nodal analysis, lift performance analysis) • Generation of updated network models for what-if studiesThe tool has an open architecture that allows information to be shared with other software packages. It is also capable of controlling and using results from other software that have open access. The tool is used daily by the POC to review the overall performance of the Greater Ekofisk Area.
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.
