Beetaloo Sub-Basin, Northern Territory : Reconstruction of thermal, burial and source rock maturation histories in the Burdo-1, Elliot-1, Shenandoah-1 and Walton-2 wells based on AFTA and Rock-Eval Tmax data

Abstract

This report describes a thermal history reconstruction study of the Burdo-1 Elliot-1, Shenandoah-1 and Walton-2 wells from the Beetaloo sub-Basin, Northern Territory, based on AFTA(r) and Rock-Eval Tmax data. Samples were provided for analysis by Hess Exploration Australia, Perth, which also provided supporting information. This final report was completed in October 2012. AFTA and Rock-Eval Tmax data have been used to identify, characterise and quantify any episodes of heating and cooling which have affected the section intersected in these wells. The results from all wells are then synthesised to provide a coherent regional thermal history framework within which the structural and hydrocarbon generation histories can be evaluated.
