Overview
TransTerra compute directly the coarse scale transmissibilities using the fine scale permeabilities. The main innovation is that calculations of coarse scale transmissibilities are performed on smaller local domain than those proposed in the conventional methods. This approach increases contrast of transmissibility and thus gains in accuracy for field scale flow simulation in heterogeneous media.
Specifications

Input data:

  • Fine scale 3D permeability properties (PERMI, PERMJ, PERMK)

Output data:

  • Coarse scale 3D transmissibility properties (TRANX, TRANY, TRANZ)
  • Index to control the quality of upscaling and gridding

Support workflow variables

Features
Compared to existing software, TransTerra uses shifted block to compute transmissibilities. Two algorithms are available:
  • Flow based method combined to algebraic method to provide a fast an accurate upscaled transmissibilities;
  • Power law.

TransTerra allows controlling the quality of upscaling and gridding. Upscaled transmissibilities can be used directly with reservoir simulator.
