Abstract: Relating Turbidite Elements to Expected Flow Character for Fluid Flow Numerical Simulation Purposes

WILLIAMS, EUGENE T., Williams Petroleum Consulting; ROGER SLATT, Colorado School of Mines

Summary

Architectural elements of turbidite reservoirs are affected by numerous factors, such as sand/shale ratio of the original deposit, shape and slope of the underlying substrate, nature of the feeder channels/canyons, and sediment transport velocities. These factors dictate whether a given volume of sediments will exhibit good or poor vertical connectivity and lateral continuity.

For many styles of reservoirs the conclusions resulting from numerical simulation can be highly dependent on the assumptions related to lateral continuity and vertical connectivity. By recognizing how deep water elastic facies relates to continuity and connectivity, simulation models can be designed using reasonable (appropriate) Kv/Kh ratios and reasonable assumptions as to the nature of the relative permeability function being applied.

This paper discusses various elements of a turbidite system and provides recommendations as to the initial assumptions related to KV/Kh ratio and relative permeability functions.
