The fast multiple-point statistics simulation software

IMPALA

by Ephesia Consult

Ephesia Consult has developped an innovative multiple-point statistics software. This software is fully parallelized, multi-platform. Non-exclusive licences for the distribution Impala have already been granted to three major software houses:

  • Baker Hughes (Jewelsuite)
  • Geovariances (Isatis)
  • Paradigm (Gocad)

    IMPALA features:

    • It is a fully parallelized algorithm which dramatically improves the CPU performances, implemented under the OpenMP and MPI protocols
    • The multi-point statistics are stored in lists rather than search-trees, thus resulting in a substantial reduction in RAM requirements
    • It proposes new methods for conditioning to existing hard data
    • It offers a wide choice of simulation path strategies
    • It can account for non-stationarity, using a-priori expert information
    • It embeds a novel algorithm to account for secondary attribute
  • In the following pages, you will find results of performance tests and examples of applications:

    IMPALA is the result of two years of intensive collaboration between Ephesia Consult (formerly FSS Consultants) and the Stochastic Hydrogeology Group of the University of Neuchâtel (Switzerland).
