Oil and Gas : High Resolution Modelling

5 October 2021

Several challenges are faced in the development of a reservoir. The reservoir simulation model must accurately predict the past, current, and future performance of the field. A strong link must exist between the conceptual model and the production data from the reservoir to ensure optimized operational management. To help address these challenges, a sector of the high-resolution reservoir model has been developed to:

  • Increase the understanding and accuracy of dynamic simulations
  • Provide operational recommendations for future development wells and the potential water injection
  • Lay a foundation for future Enhanced Oil Recovery (EOR) modelling

This case study focuses on a fractured and karstified reservoir. From the perspective of dynamic modelling, it is important to capture the disparity between permeability and fluid flow anisotropy. Improvement in the horizontal and vertical resolution of specific model sectors results in less upscaling biases, and in turn yields a more detailed characterization of the fracture network, specifically karst-related fractures and geobodies. This results in a better representation of the structural framework including minor faults and complex geometries (stair-step grid), and a better representation of the matrix heterogeneities.

Information from the sector models is incorporated into the full-field simulation model which are subsequently used as a valuable tool to support operations.
