On the possibility of indicating a coupled system of cracks in crosshole space

Authors: R.G. Alkhimov, I.L. Yevstafyev, A.M. Semenov (GazpromVNIIGAZ LLC, RF, Moscow) E.Yu. Golichenko (Gubkin Russian State University of Oil and Gas, RF, Moscow)

Key words: field development, reservoir engineering, geological uncertainties, algorithm, field properties

To predict the connectivity or discontinuity of cracks network an algorithm is proposed, which is based on the criteria, using multipoint spatial correlation. To train the algorithm two sets of stochastic realizations of a fractal cracks network are applied: the first set contains super-reservoir in unexplored area of deposit, the second set includes only local highly permeable zones. The main idea of the proposed algorithm is described conceptually.
