Operators achieve photorealistic borehole imaging in oil-based drilling fluids ///

Drilling a 12¼-in borehole with oil-based mud (OBM) in the Upper Mungaroo formation on Australia’s North West Shelf, an operator needed to characterize reservoir geology and assess economic potential as accurately and expeditiously as possible. Geological objectives included identifying reservoir-quality channel sands and laminations, determining the presence and connectivity of non-channel facies, and calculating the dip and orientation of structural features, such as faults.
