This article discusses the linkage between 4D seismic responses and geomechanics. Exploitation of this relationship has helped reduce development costs and maximize recovery from the compacting Valhall reservoir. The 4D…

Permanent seismic monitoring is an emerging market with significant potential. Who are the major players and what has been done to validate the Optowave technology? This article has been designed…

The use of geophysical methods in petroleum exploration continues to expand and is an integral discipline in the discovery and production of oil and gas deposits. We have seen a…

The main purpose of applying EM data is to improve exploration decision making. “As a geoscientist working in an oil company which values integration, we try to maximise the use…

Electromagnetic surveying is one of the least well understood of the non-seismic exploration techniques. There are various acquisition choices to be made – for example it can be undertaken using…

Modelling reservoirs using a 3D grid is a common tool for both the geologist and the reservoir engineer. As models increase in structural and stratigraphic complexity the process of creating…

Large-scale volcanism caused by a superplume in the mantle was possibly responsible for wide-spread deposition of excellent source rocks in Mid-Cretaceous times. Organic rich source rocks buried deep in sedimentary…

In 2008 the Optowave fibre-optic seismic sensor cable was trenched at the StatoilHydro-operated Snorre field with the aim of achieving insight into installation, data acquisition and monitoring procedures. The Snorre…
