Morphometrics of Channel Belts from the Mungaroo Formation, NWS, Australia

Presented by Tobi Payenberg

Abstract:

Understanding the deposits of different fluvial styles is fundamental to improve the characterization of fluvio-deltaic petroleum reservoirs. Fluvio-deltaic systems host significant hydrocarbon accumulations around the world, including reservoirs of the Mungaroo Formation, North West Shelf, Australia.

The Mungaroo Formation is a Triassic-aged, over 4 km-thick, fluvio-deltaic succession with 20–30% net-to-gross overall. Despite hundreds of wells drilled through the Mungaroo Formation, lateral facies variability remains a significant uncertainty in reservoir development predictions because of the generally large well spacing and challenging facies variability in this offshore environment. The lack of high-density wells necessitates references to outcrop and subsurface analogues to fill in fine-scale heterogeneity predictions away from well control within the framework of coarser-scale qualitative and quantitative seismic interpretations.

Seismic geomorphology workflows applied to the Mungaroo Formation allow the mapping of individual channel belts and channel belt complexes. Little detail of channel belt internal architecture can be imaged. A morphometric analysis of channel belt planforms from satellite images were calibrated to seismic data to create a quantitative database for fluvial types distinguished by their bar and channel sizes and distributions. Morphometry of satellite images provides proof of concept that modern channel belt shapes, interpreted from around the globe, can be related to channel and bar processes that control inter-channel-belt facies patterns. Using these observations, predictions of fine-scale heterogeneity based on the morphometry of seismically-imaged channel belt planforms can be made. Seismic data validated by closely spaced subsurface Mungaroo well data can be compared to satellite-based data, supporting the robustness of the morphometric approach.

Moving forward, the morphometric analysis of channel belts from seismic data is a powerful tool for assessing the reservoir heterogeneity inside channel belts in exploration plays when fine-scale facies variability needs to be predicted, and in reservoir modelling where it allows for more accurate reservoir development forecasts.
