Cambridge: ARKeX, a worldwide player in geophysical imaging technology, has raised $30 million in a deal that marks the largest venture capital round in this sector for five years.

Led by Ferd Venture of Oslo, Norway; the investment round was participated by existing investors including Energy Ventures of Stavanger, Norway; Scottish Equity Partners of Glasgow, UK; and members of ARKeX senior management. This is the third round of funding raised by ARKeX since 2004 and the largest venture round for a service company supplying the onshore and offshore oil and gas E&P sector since 2003.

ARKeX's technology has already had a significant impact on exploration strategy by reducing overall exploration risk, making it a valuable leading-edge exploration tool for major energy corporations.

The company will use the funds to expand the operational capabilities of its airborne BlueQube gravity gradiometry imaging service and to accelerate production of its proprietary technology, the Exploration Gravity Gradiometer (EGG).

ARKeX's gravity gradiometry technology measures minute variations in the earth's gravitational field. It helps resolve complex geology, overcome seismic imaging difficulties and survey large areas quickly and cost effectively. Gravity gradient imaging is becoming an increasingly important tool for oil, gas and mining exploration companies and the new investment will take ARKeX's BlueQube service to more globally diverse energy basins.

"This is a major step forward for ARKeX," said Kitty Hall, Chief Executive of ARKeX, "ARKeX has performed surveys in North America and Africa, but there are many more basins of the world where our technology will be of vital importance. This investment means we can establish our services in new regions and accelerate the rollout of our EGG systems to meet increasing demand."
