Petratherm said the quality of the raw data was good and would be processed in preparation for geological interpretation.

In addition, two seismic lines shot over the area in 1984 would be reprocessed to current specifications.

This historic seismic data over the Paralana region indicate numerous faults within potential deep reservoir horizons, Petratherm said.

“These structures may greatly improve local permeability and fluid circulation. The newly acquired seismic survey will more accurately constrain the geometry of these reservoir horizons and the faults,” the company said.

“This will enable optimal placement of the scheduled deep geothermal production well.”

To support the seismic reservoir characterisation work, the partners are also planning a magneto-telluric survey in December.

The magneto-telluric survey will provide further information on the geometry of potential reservoir zones, and may also define naturally occurring fluid pathways.

“These important pre-drill studies greatly increase the probability of a successful first production well,” Petratherm said.

“To this end, the company is close to finalising the first deep well design aided by external consultants with experience in both the petroleum and geothermal industries.”

Subject to rig availability, the first deep well at Paralana is expected to spud in the second or third quarter of next year.
