6.2.1 Reservoir management and drilling operations

Solution for data acquisition, modeling
and visualization between facility
operators and central company experts to
provide:

• Drilling simulation and
visualization, automatic
diagnostics and decision support,
realtime measurements while
drilling in order to locate the best targets
• Reservoir models based on real-time reservoir data, analysis of 4D
seismic, in-situ measurements of changes. On-line integration with
well-serviced company data
• Optimization models for increased production, based on in-reservoir
properties during production, with decision support incorporated to
improve productivity

6.2.2 Production optimization

Optimizing the production or improving productivity is a complex problem. In
addition to the production optimization of the downhole-, subsea- and
topside process, one has to
consider operational costs,
hardware damage, reservoir
performance, environmental
requirements and operational
difficulties within each well and/or
topside. To further complicate
optimization, the individual
challenges will change over time,
e.g. reservoir behavior changes
as an effect of depletion,
shutdown of wells due to
slugging, failed sensors and the
change of efficiencies within the
topside process system. Some of the applications included in production
optimization are:

• Flowline Control to stabilize multiphase flow in gathering systems,
risers and flow lines.
