Abstract

Summary

The study focuses on the stratigraphy and depositional framework of the Wara reservoir. In particular it illustrates how production-related decisions can be guided by both i) an appropriate reservoir layering scheme and ii) population of reservoir layers with depositional elements guided by analogue data. The reservoir layering scheme identifies three reservoir flow units, bound by laterally extensive mudstones, which may be correlated across the Early Wara Pressure Maintainance Project area:

  • A Lower Wara Formation flow unit comprising multi-storey fluvial/tide-influenced deposits.
  • Two Middle Wara Formation flow units comprising a complex assemblage of channelised and more sheet-like sand bodies.

Production data from the study area indicates that communication between these flow units is highly baffled as a result of the extensive bounding mudstone layers. This has implications for zonal perforation strategies and injector-producer conformance
