Rockwater used its proprietary code PyGeo to conduct a basin-wide analysis of the Levelised Cost of Electricity (LCOE) of geothermal electricity generation in one of Western Australia’s foremost onshore sedimentary basin.
Unlike simple temperature mapping analyses, the code combined temperature information with Monte-Carlo porosity and permeability values to produce probabilistic estimates of the achievable geothermal power versus depth.
The results of the basin-wide assessment were used to identify sub-areas within the basin with high potential. For these areas, the PyGeo code used reservoir specific porosity and permeability trends combined with seismic horizon grids and temperature grids to generate spatial LCOE maps.
The Rockwater workflow was highly successful and contributed to the identification of two areas with a 20 MW+ potential and competitive LCOE.
Rockwater is the leader in developing geothermal resources in Australia.
