OFFSHORE HYDRO : Bridge Energy UK Ltd Awards OHM Rock Solid Images a WISE CSEM contract in the North Sea

Offshore Hydrocarbon Mapping plc (AIM:OHM), is pleased to announce that it has been awarded a CSEM contract, worth in excess of $1 million, in the North Sea, by an existing client, Bridge Energy UK Ltd (formerly Silverstone Energy). The project, under OHM's WISE (Well Integration with Seismic and Electromagnetics) product includes providing the client with a fully integrated dataset, comprising seismic, CSEM and well information. The OHM Express, a state-of-the-art vessel for conducting safe and reliable CSEM operations, will acquire the CSEM survey and is expected to commence this project in late summer.

This project is the second to be awarded to OHM by Bridge Energy UK, and follows on from a previous successful North Sea CSEM acquisition and interpretation survey conducted for Silverstone in 2007.

Richard Cooper, Chief Executive Officer of Offshore Hydrocarbon Mapping commented:

?CSEM works best when tightly integrated within a framework constrained by seismic and well data. Our WISE methodology combines advanced seismic and well processing with CSEM surveying and interpretation to provide a reliable and robust appraisal tool.?
