The solution is based upon a number of elements of Emerson’s AMS
Suite: Real-Time Optimizer system and includes process modeling and optimization, data conditioning
and performance updating of the wells and flowlines. The system is based
on a Windows NT platform, and can be accessed from across the BP site
network.
The system represents all of the wells on the 7 major wellsites and the
interconnecting flowlines, enabling the overall production from the asset
to be maximized. The system also considers the cost of the electricity
required to drive the well pumps and the merit of producing from different
areas of the reservoir.
A key feature of the system is its ability to consider the wells and
flowlines as a complete entity rather than individual units. This gives
the optimizer the ability to evaluate competing potential operating
changes and determine which are the best for the asset as a whole. This is
important because, whilst plant personnel fully understand the effects of
individual well changes, the optimizer enables the overall, plant-wide,
effect of well changes to be evaluated.
The system provides both on-line recommendations of optimal well
operating conditions and an off-line tool, which is kept up-to-date with
the current performance of the wells and flowlines. This facilitates
simple evaluation of potential modifications, e.g. pipeline
unavailability, well workovers and contingency planning.
The system also assists well and pipeline performance monitoring, in
reservoir management issues, data reconciliation and validation.
The system is used both by process engineers to evaluate different
operating scenarios and hydrocarbon accountants to acquire detailed oil
allocation information.
