Offshore Hydrocarbon Mapping (OHM) has completed the acquisition of Houston-based Rock Solid Images (RSI). RSI is a industry leader in the integration of fundamental rock physics with well data and surface seismic in order to interpret geophysical signatures in terms of reservoir properties such as lithology, porosity and saturation, providing geologic insight and reservoir understanding at all stages of the oilfield lifecycle; it is OHM’s intention to invest in RSI to allow them to grow this business and to develop their technical lead.
Controlled Source Electromagnetic imaging (CSEM), provided by OHM, is an innovative offshore geophysical technique, employing electromagnetic remote-sensing technology to detect the presence and extent of hydrocarbon accumulations below the seabed.
The acquisition is driven by the belief that highly valuable information can be gained from the intelligent combination of CSEM and seismic data, calibrated where possible by well log information. OHM and RSI’s researchers consider that these two remote sensing measurements are completely complimentary and, when properly combined, can lead to quantitative measurement of important rock and fluid properties such as permeability and hydrocarbon saturation.
