Data Driven Surveillance and Optimization

Abstract

Abstract Traditionally individual well oil, gas and water production is measured periodically e.g. monthly, using shared well test facilities. Consequently, oil and gas production from a cluster of wells is difficult to manage, leading to late diagnosis of production problems and slow and conservative handling of production constraints. FieldWare Production Universe (FW PU) is a software application developed by Shell that provides continuous real time estimates of well-by-well oil, water and gas production. FieldWare PU estimates are based on data driven models constructed and updated from production well tests and real time production data. This paper will discuss use of FieldWare PU for continuous optimization by predicting changes to overall and individual well production as a result of changes to individual well production chokes, lift-gas rates or other similar set-points to maximize an objective function subject to various well and overall production constraints.
