VIALOGY SIGNS RENEWABLE ENERGY CONTRACT WITH ENEL NORTH AMERICA TO CHARACTERIZE AND DE-RISK GEOTHERMAL PROSPECTS

n ViaLogy technology extended to green energy

n Goal is reduction of exploration/drilling risks/costs

London, March 10. ViaLogy (LSE:VIY) announces signing of a contract with Enel North America, a subsidiary of Enel Green Power, the Enel Group company operating renewable energy sources in 14 countries, including the US. Enel Green Power is one of the world's leading players in the renewables industry and a global leader in geothermal power generation. The Enel Group is Italy's largest power company and Europe's second listed utility by installed capacity.

Under its initial contract, ViaLogy will extend its QuantumRD sub-surface detection technology to seismic survey design, and the identification and location of appropriate geothermal drilling locations at an Enel North America site in Nevada.

Geothermal energy generation obliges commitment of very large capital resources, and a determining factor in the geothermal business equation is the inordinately high cost of exploration, drilling and extraction which entails significant risk. Geothermal well positioning requires robust detection and characterization of natural cracks and fractures in volcanic regions with extremely hard rock; accurate mapping of fractures and discontinuities forming pressurized traps; and mapping formations that can support drilling holes with large diameters in hard rock.

QuantumRD's ability to assess complex subsurface stratigraphy, porosity and fluid saturation levels more accurately than other current technologies, utilizing seismic, magneto-telluric and other chemical tracer data, should reduce risk and alter the sector's investment risk profile. Over time, this could contribute to the broader use of clean, environmentally sustainable geothermal-based electricity.

ViaLogy's Energy business focus remains squarely on the upstream hydrocarbon industry sector where its QuantumRD technology is projected to build upon its success thus far to become an industry standard. But the opportunity to bring its technology to bear in such a vital and financially promising part of the green energy industry is important to the company's future success and earnings, as well as an opportunity to do its part in mitigating the effects of global warming.

ViaLogy CEO, Robert W. Dean, said, "The Enel contract opens up a new market for us in renewable energy development. It broadens our business base, and provides yet another means of developing and refining our QuantumRD technology, and could be a significant source of 'green' growth."
