PRM project management solutions in oilfield reservoir monitoring

During our history as a founding part of the original WGP Group  of companies, AquaGeo has amassed expertise gained over a decade of work supporting reservoir monitoring operations with an outstanding technical and HSE record.

This experience began when members of our team where contracted by BP as the lead supplier in the world’s longest running seismic PRM application at the Valhall oil field in the North Sea.  Following on from the success of this project, our role with BP evolved into providing a custom turnkey solution around the Chirag and Azeri Reservoirs in Azerbaijan. The project spanned a period of 4 years.

We are able to design, build and operate a solution to monitor reservoir behaviour and to maximise hydrocarbon extraction through improved reservoir management practices.  Offshore seismic permanent reservoir monitoring (commonly known as PRM) is a seabed-based technology designed to maximise well recovery of hydrocarbon fields. PRM involves conducting 3D seismic surveys at regular intervals using repeatable methods and equipment.

The main objective of PRM is to increase survey accuracy and to monitor and interpret geological changes in the reservoir.  This leads to a situation where well recovery is maximised and risks are reduced. The data acquired gives engineers invaluable information used to plan well management in the most efficient manner.

As a service company, we see our role in designing and operating PRM equipment and systems that are owned by the oil company client. The cost of owning the necessary capital assets necessary to deliver a PRM solution are a relatively small part of the total oil field budget and are a small percentage of the likely uplift from increased production. PRM equipment can be rapidly mobilised on to vessels already chartered into the oilfield support operation and there are no issues regarding repeatability of survey parameters as the same equipment is always deployed on each oil field operation. Oil company PRM asset ownership removes dependency from the “turn key” contractor who may change equipment, vessels or personnel and also undergo changes in corporate structure between PRM surveys.

Reservoir monitoring is a proven successful tool, not only for enhanced well projection, but also for well integrity observation.  Coupled with today’s competitive climate and a move to maximise current reserves in favour of new exploration, it is likely that oil field asset management is here to stay.
