"Geostatistical
Modeling and Reservoir Engineering - Is There a Common Life Possible?" by Dr.
Georges A. Blanc
Abstract
In early 90's the most popular use of Geostatistical Modeling of Reservoirs was for
evaluating the impact of geological modeling on production forecasts. Since a
geostatistical model makes it possible to simulate an infinite number of realizations,
running numerical simulations on a finite subset of these realizations was used to capture
the geological uncertainty.
No tools nor methods were available at that time to history match a
geostatistical model while keeping it consistent with the initial geological hypothesis.
This lack of technology restricted the use of geostatistical modeling exclusively to the
study of new oil fields. Due to this shortcoming, the use of geostatistical modeling in
day to day reservoir engineering studies was declining.
In the past five years, much research work has been devoted to the
general problem of integrating dynamic data in geostatistical modeling. Well tests were
considered at first, followed by production data. Today, several solutions such as
automated history matching and controlled deformation of geostatistical models are
available. It is now possible to history match both the geological and the petrophysical
model properties.
Several examples presented in this lecture illustrate the quest for a
fruitful cooperation between geologists and reservoir engineers and demonstrate that they
are closer than ever to a mutually satisfying alliance.
Dr. Georges A. Blanc
Georges A. Blanc is presently the Manager of the IFP Office in Pau (France). He is also
the scientific manager of a Joint Elf EP-IFP Research program devoted to the
"Evaluation and Reduction of Uncertainty in Reservoir Production induced by
Uncertainty in the Reservoir Modeling" operated by the IFP at their Pau Office since
end of 1993. He has more than 35 years of experience in Reservoir Engineering and Software
Development. He has been an SPE member since August 1980 and has participated in several
SPE-Applied Technology Workshops. He is member of the Steering Committee of the 2000 SPE
ATW "History matching: Advanced Technologies". He has presented or published
more than 30 technical papers and is coauthor of a book. Georges A. Blanc holds an
engineering degree from Ecole Nationale Supérieure d'Hydraulique de Toulouse and a PhD
degree from Toulouse University, in fluid flow in porous media.
