Special report: A 2D Seismic Environmental Management Plan (EMP) for EP145 in the Amadeus Basin of central Australia has been accepted, allowing Greenvale to start planning its exploration programs.

Greenvale Energy (ASX:GRV) completed the acquisition of a 75% interest in Ep145 from Mosman Oil and Gas in the Amadeus Basin in central Australia in April, opening up a new exploration and growth opportunity for shareholders.

The Amadeus Basin has a long history of hydrocarbon production.

Helium and hydrogen production have been proven through exploration drilling, with some of the highest concentrations of helium globally, highlighting its potential to become a world-class province for helium and hydrogen.

Ep145 hosts an existing prospective resource estimate, with a “Best Estimate” of 440 billion cubic feet (Bcf) total gas, including 26.4 Bcf of helium and 26.4 bcf of hydrogen.


Seismic program targeted for completion in August

Preparations are now underway for a seismic program that will be completed before the end of 2024 to guide targeting for drilling in 2025.

The 2D Seismic Environmental Management Plan (EMP) for EP145 in the Amadeus Basin in Central Australia has been submitted to and accepted by the Department of Environment Parks & Water Security (DEPWS), a key milestone in the process to begin exploration programs.

GRV says the survey will comprise 118km of 2D seismic lines and has been designed to acquire additional seismic data along the southern extent of the West Walker anticline to understand the pre and post salt structure and stratigraphy.

EP 145 sits near existing critical gas infrastructure, providing a pathway to near-term commercialisation as well as the opportunity for GRV to become a supplier to the rapidly growing helium market, which is experiencing severe supply shortages and strong demand growth and pricing.


‘Exciting asset”

“The permitting and approvals process for this 2D seismic program for EP145 is progressing smoothly, with the start of this survey representing a key milestone to allow us to finalise drilling locations to test the significant potential of this exciting asset,” GRV CEO Mark Turner says.

“Ongoing work programs by Greenvale and other operators in the Amadeus Basin will help us to fully evaluate the significant helium and hydrogen potential of this region and advance this exciting project for the benefit of our shareholders.”


All long-lead items ordered

So far, all remaining long-lead items required for the 2D seismic program have been ordered including the dynamite, which has already been acquired and received, and the detonators which have been ordered from France and are expected to arrive by mid-July.

This allows the nominated contractor to lock in the drill rigs and heli-support required for the mixed source (dynamite/weight drop) program, which are the final items required for the 2D seismic program.

The Wild Horse 2D survey is currently scheduled to begin in August, pending the approval of the EMP.

Seismic acquisition is expected to take place over the months of August and September.
