Norwest boosts Lockyer Deep-1 well

Cervantes-1 well is located in the Perth basin

Norwest Energy has announced an increase in potential resource area for the Lockyer Deep-1 well, Western Australia.

The oil and gas exploration company has recently revised its interpretation of the available seismic data, incorporating several new datasets from the seismic reprocessing program that was completed in August of this year.

Well data from the Lockyer Deep-1 well was also incorporated, and the resulting structural mapping indicates that the potential resource area has increased by 40 per cent from 66 km2 to 92 km2.

The potential resource area is regarded as the area down to a Top Kingia depth of 4,500 m, being the Indicative Free Water Line extrapolated from reservoir pressure data and based upon known regional water gradients.

Previously the potential resource area excluded the southern portion of the structure, which at the time was thought to be separated from the discovery by an east-west trending fault.

As such the area to the south of this fault was at that time considered a prospective resource.

Norwest managing director Iain Smith said a conservative approach was taken to mapping the structure prior to drilling Lockyer Deep-1 and he was pleased to present the revised interpretation that demonstrates the true potential of the discovery.

“We now look forward to production testing of the Lockyer Deep-1 well, the timing of which will be announced as soon as details are known,” he said.

Norwest’s interpretation of the Lockyer Deep/North Erregulla Deep structure is now broadly consistent with that of its joint venture operator, Energy Resources.

The Lockyer Deep discovery is located within Exploration Permits EP368 and EP426.

Norwest Energy is a Perth Basin focused oil & gas exploration company headquartered in Perth, Western Australia, and the company hold interests in an extensive portfolio of exploration permits, both onshore and nearshore.
