Scottish company Adrok has developed an advanced Atomic Dielectric Resonance (ADR) technology that uses ‘virtual boreholes’ to provide accurate data on rock layers.

Adrok’s technical paper, which was published in the latest edition of IJRS, describes the use of ADR as a geophysical technique for precise geological recognition of rock layers and the identification of rock types.

ADR uses low-power radio wave and microwave transmissions for deeper subsurface penetration.

According to the technical paper, field tests in central Scotland recorded accurate rock layer measurements at different penetration depths, the deepest being 700m.

The company beleives that ADR offers a cost-effective and environmentally friendly geophysical service to oil, gas and coal companies by reducing the number of drill holes required during exploration and remotely deducing subsurface technology.

Adrok managing director Gordon Stove said that it was the company’s long-term plan to develop ADR technology as an alternative exploration technique.

"Our current customers have already recognised the benefits of ADR and as a result we recently received an investment of £3m from Canada’s Teck Resources to carry out more developments on the technology," Stove added.

"However, to have the work accepted by our peers at the IJSR is a huge triumph for us in terms of establishing ADR as a real alternative to current testing methods and we are looking forward to developing the technology in the future."
