Raphael developed the 3D GravMag technique, a proprietary processing of gravity and magnetic data that maps structures at depth. Processing of SPA-89 gravity and magnetic data has mapped multiple 3D GravMag structures with extraordinary geometry within SPA-89:
Vast areas - Located in a tectonically quiescent area of the Officer Basin, SPA-89 structures have areas as great as 109 km2 (26,900 acres) and average 60 km2 (14,900 acres).
Massive thickness – SPA-89 structures are as thick as 1,200 meters (3,900 feet) with an average thickness of 626 meters (2,040 feet), consistent with four wells drilled to the west of SPA-89 with massive sedimentary sections. For example, the Hussar formation is as thick as 890 meters (2,920 feet) and averages 638 meters (2,090 feet). Significantly, in addition to massive thickness, the Hussar formation has excellent petrophysical properties with average net to gross reservoir of 38% and average porosity of 20%.
Along with the vast areas and massive thickness, basin exploration has confirmed the presence of an active petroleum system with a high concentration of oil and gas shows in wells to the west of SPA-89.
With 3D GravMag structures with vast areas and massive thickness plus hydrocarbon shows in multiple wells in the area, SPA-89 has iconic potential.
