Post-drill analysis to assess the prospectivity and geological risks for energy resources in the Pedirka, Simpson and western Eromanga basins
<div>The Permian Pedirka, the Triassic Simpson and the Jurassic–Cretaceous western Eromanga basins in central Australia have undergone a sporadic exploration history which commenced in the 1950s. Exploration initially focused on conventional hydrocarbons from the 1950s–1980s, before shifting towards coal seam gas (CSG) opportunities in the 2000s. The basins remain underexplored with only 42 wells drilled, and ~16,000 line km of 2D seismic acquired across a study area of ~210,000 km2. An active petroleum system has been proven by a non-commercial oil discovery at Poolowanna 1, as well as by several wells that show evidence of residual oil columns. However, sparse and low-quality seismic data make it challenging to map and identify new energy resource opportunities.
Geoscience Australia, the Northern Territory Geological Survey, and the South Australian Department for Energy and Mining are collaborating on the Australia’s Future Energy Resources (AFER) project to undertake an assessment of the resource potential for conventional and unconventional hydrocarbons and the carbon capture and storage (CCS) potential in the Pedirka, Simpson and western Eromanga basins. The project’s objective is to produce spatially-enabled and risked resource estimates to provide government and industry stakeholders with decision making tools to address the region’s energy resources and CCS potential.
Post-drill analysis is a key component of evaluating the resource potential of a region by ensuring that a systematic, data-driven approach is used to evaluate discrete exploration play intervals and trapping mechanisms. The study area has been divided into 16 chronostratigraphic play intervals and post-drill analysis has been undertaken to evaluate the presence and effectiveness of the main conventional petroleum systems play elements of reservoir, seal, trap and hydrocarbon charge. The post-drill analysis methodology to assess conventional hydrocarbons has also been modified to assess the geological elements that are essential to evaluate unconventional petroleum resources and CCS potential within the study area. The qualitative results indicate conventional hydrocarbon, CCS, CSG and shale hydrocarbon opportunities across multiple plays, highlighting that an area that has been primarily explored for one resource type in the past may have other opportunities for industry to evaluate.
