Abstract
With the increasing exploration interest in onshore unconventional resources, Geoscience Australia's onshore hydrocarbons section, in collaboration with the United States Geological Survey (USGS) and Australian States and The Northern Territory Geological Surveys, will undertake a pilot unconventional resource assessment of the entire Georgina Basin. As part of this process to produce a nationally consistent dataset in this space, new geochemistry and petroleum systems modelling will be presented for the basin. The Georgina Basin is a northwest-southeast trending extensional basin, which covers up to 325,000 km2 in both Queensland and the Northern Territory. The basin contains thick successions of Neoproterzoic through to Lower Devonian sedimentary rocks and potential Cambrian hydrocarbon systems, with some parts of the Northern Territory portion of the basin considered to be within the oil window, with prospective Cambrian and Ordovician carbonate and clastic sedimentary rocks (Questa, 1994). The assessment will use the USGS probabilistic framework of assessment, based on predicted productivity (either from actual production data or analogues), which distinguishes it from the commonly used volumetric methods. The geological framework uses inputs for the resource assessments constructed through the integrated interpretation of a variety of geological and geophysical datasets to produce, for the first time, basin wide volumetric assessment of unconventional hydrocarbon plays for the Georgina Basin.
