Northern Territory experience strongly preferred; experience in the Pedirka, Amadeus, Eromanga, Cooper or comparable basins highly regarded.
n
Strong seismic interpretation, structural and stratigraphic capability.
n
Demonstrated experience in prospect generation, risking, volumetrics and well-target maturation.
n
The ability to work effectively across geology, geophysics, petrophysics, reservoir engineering and drilling.
n
Experience with Petrel, Kingdom or DecisionSpace and GIS tools.
n
Transparent technical writing and communication skills.
n
Experience in geological carbon storage, underground gas storage, injectivity, seal or fault analysis is advantageous but not essential.
