Abstract:
The Murteree Horst is located in the southern Eromanga Basin, South Australia. It is a long-lived basement high that has been subject to Tertiary reactivation, hosting a substantial number of oil fields at several stratigraphic intervals. The large JALBU (Jena-AlwynLimestone Creek-Biala-Ulandi) complex is the largest hydrocarbon field and contains oil in the Early Cretaceous Murta Formation. Across the horst and along the flanks there are also a number of deeper Jurassic oil discoveries, originally thought to be hosted within the Hutton Sandstone. Regional correlation of these columns reveals that often the oil saturation is stratigraphically higher than the true Hutton Sandstone, and is present invariably developed fluvial channel sand bodies within the Birkhead Formation. Occasionally these channel sands are so well developed they appear, from a lithostratigraphic perspective, to be Hutton Sandstone.
