A techno-economic feasibility research commissioned by Earths Vitality identifies the Paralana geothermal website in South Australia as a goal for EGS growth.
Australian geothermal developer Earths Vitality (EE1) has introduced the outcomes of a Techno-Financial Feasibility Examine performed by GLJ Ltd. (GLJ) indicating that the Paralana website in South Australia is an appropriate goal for an Enhanced Geothermal System (EGS) growth. The TEFS work now progresses to reservoir simulations, value estimation, and financial modeling, and is on observe to be accomplished by December 2024.
The TEFS work was performed for each the Paralana and West Flinders website of EEI in South Australia, following up on a evaluation beforehand performed by JRG Vitality that indicated that these belongings have the potential for business electrical energy technology. The corporate has now spent greater than $40 million in fieldwork and research for these two geothermal websites.
“GLJ’s preliminary findings affirm our perception in Paralana’s potential as an Enhanced Geothermal System undertaking. Independently validating Paralana’s permeability and stress circumstances for EGS growth is each vital and invaluable,” stated Josh Puckridge, CEO of Earths Vitality.
“Momentum round EGS is constructing, spurred by pioneering successes within the USA, the place initiatives in Nevada and Utah are setting the stage. Paralana stands alongside these main efforts, and our collaboration with GLJ will showcase this additional. Earths Vitality is devoted to quickly advancing Paralana as a world-class EGS undertaking, backed by GLJ’s experience and our expert group.”
Paralana as precedence EGS goal
GLJ’s work has confirmed that the Paralana Mission, drilled to three,685 metres with a backside gap temperature of 171°C, has beneficial traits for an EGS growth. The TEFS has highlighted beneficial permeability at Paralana, the place zones of present fractures have been interpreted from borehole picture knowledge and micro seismic monitoring throughout stimulation beneath the 150°C isotherm depth within the Paralana-2 properly. In-situ stress fields with a principal horizontal stress roughly within the E-W path had been noticed above the goal depths, which seem to supply a beneficial horizontal properly drilling stress setting for EGS implementation.
The TEFS has additionally proven that the Flinders West licenses require further subsurface analysis and doubtlessly exploration drilling to additional derisk the geothermal potential for EGS.
As such, growth of Paralana will likely be prioritised, whereas the Firm will take a look at choices to agency up the subsurface knowledge out there for Flinders West, together with collaboration with different teams within the space.
