The Beetaloo sub-basin is a Mesoproterozoic to Neoproterozoic sedimentary basin that overlies the western extension of the McArthur Basin. The basin is bounded by several prominent structural elements including the Walton High to the North, the Bauhinia Shelf to the East, and the Helen Springs High to the South. The western margin is defined by the Daly Waters Arch, which separates the Beetaloo sub-basin from the Elsey Gravity Low, also referred to as the Gorrie Sub-basin.
The target source rock intervals of the Beetaloo sub-basin are found within the Mesoproterozoic Roper Group, a thick sedimentary package consisting of quartz sandstones, siltstones, and organic-rich siliceous mudstones. The Velkerri Formation (~1.4 billion years old) of the Roper Group has been identified as a prospective unconventional exploration target.
Donny received his BS in Biology/Secondary Education from Asbury University in Wilmore, KY in 1998 and his MA in Secondary Education from Georgetown College, Georgetown, KY in 2006. After ten years of teaching middle and high school science in Lexington, KY, he left the teaching profession to pursue his MS in Geology, which he received from the University of Kentucky in 2010. He joined Pioneer in 2010, where his initial role was focused on operations and development geology for the company’s assets in the liquids-rich Barnett Combo Play of the Ft. Worth Basin. After that, he worked as a regional geologist on the Southern Wolfcamp and Permian Asset Teams, focusing on geologic, petrophysical, and geomechanical mapping and analysis for appraisal, drilling optimization, and development of Pioneer’s Midland Basin Wolfcamp and Spraberry assets in west Texas. He also worked in Pioneer’s Water Management group where he managed a technical team aimed at characterizing saltwater disposal zones in the Midland Basin. Under his leadership, the team completed a full geologic and reservoir characterization of the basin’s shallow San Andres and deep Ellenburger disposal zones, developing depositional, diagenetic, and porosity evolution models for both intervals as well as a static 3D geocellular facies model used for numerical modeling, disposal capacity estimation, and pressure prediction. He recently joined Tamboran Resources LTD, based in Sydney, Australia as the company’s Geoscience Technical Advisor, where he is focused on exploring for hydrocarbons in the gas-rich Beetaloo Sub-basin in Australia’s Northern Territory. Donny’s interests include hiking, backpacking, playing the drums, riding motorcycles/ATVs, playing softball and beach volleyball, binge-watching ‘90s sitcoms on Netflix and, most of all, spending time with his wife and two children at their home in Carrollton, TX.
