Abstract

The late Triassic Mungaroo Formation is a prolific gas-condensate reservoir along the landward margins of the Exmouth Plateau (i.e., Gorgon and Rankin trends). Recent exploration drilling has stepped outboard of these trends into the Exmouth Plateau adding calibration to an area of sparse well control. Reservoir units were primarily channelized complexes of variable widths and orientations within a large fluvial-deltaic complex that formed a thick (>2.5 kilometer) succession. Channel complexes were attractive exploration targets and have been the reservoirs of recent discoveries.

Mungaroo channelized complexes were thick >10 meters, multistorey, and greater than 1 kilometer in width. Their depositional origins were considered either distributaries or channels within an incised valley. Reservoir characterization studies has provided ranges in the properties of the channels, internal reservoir architecture and expected facies distribution that allowed for gas initially in place (GIIP) and estimated ultimate recovery (EUR) calculations.
