OHM and Rock Solid Images to cooperate on integration of electromagnetic data with wellbore and seismic data
Houston and Aberdeen, June 2006 – Offshore Hydrocarbon Mapping plc (OHM) and Rock Solid Images (RSI) are working together to advance the integration of seismic and well log data with CSEM.
The co-operation agreement means that, for the first time explorers will be able to evaluate their exploration prospects using a fully integrated data set incorporating seismic, controlled source electromagnetic imaging and well log data. The fully integrated data will provide clients with a heightened level of information on likely rock and fluid properties and improve upon the direct detection of hydrocarbons.
Dave Pratt, CEO of OHM plc, commented: "CSEM is an exciting value added technology that provides a new remote sensing measurement of the properties of the earth. We can substantially increase the value that can be derived from CSEM data by integrating it with other geophysical information. This integration will improve the answers we can give to explorationists and reservoir engineers. RSI has in depth expertise in many of the areas of data integration that we are interested in, and shares our vision of how to assess rock and fluid properties from integration of remote sensing data."
Added Richard Cooper, President of Rock Solid Images: "OHM's CSEM processing and inversion workflows perfectly complement the well and seismic methods developed at Rock Solid Images. We believe rock-physics relationships hold the key to integrating seismic and well-log data for quantitative interpretation. We are extending these rock-physics relationships to accommodate CSEM data, permitting simultaneous interpretation of seismic and EM data within a unified, borehole-based rock and fluid model. In this way we combine the strengths of both types of data and obtain information which would not be available from either one alone."

Notes to Editors:
Offshore Hydrocarbon Mapping plc is headquartered in Aberdeen, Scotland and its shares are listed on the Alternative Investment Market of the London Stock Exchange (OHM). OHM's survey method transmits an electromagnetic field into the earth, which is modified by the presence of subsurface resistive layers. These changes in the field are measured and the resulting data is processed to provide information on the resistive structure of the subsurface. Because hydrocarbon accumulations are generally very resistive, this method can indicate the presence of oil and gas in water depths of as little as 50 metres in certain circumstances and can detect and map the edges of such accumulations. This reduces the risk of drilling non-commercial exploration wells and can reduce the need for appraisal drilling, thereby creating considerable value for oil explorers.
Rock Solid Images is a private corporation based in Houston, Texas, and provides solutions for seismic reservoir characterization, and specializes in the integration of surface seismic and borehole data to build seismic-scale models of reservoir properties such as porosity and fluid saturation. In addition to providing turnkey seismic reservoir studies, Rock Solid Images develops software for rock-physics and seismic modeling and seismic attribute calculation and classification via industry funded consortia.
