A Quick Look Kriging Technique for Reservoir Characterisation

Correct descriptions of reservoir rock heterogeneity provide useful input for simulation models and are essential for efficient reservoir management.

This paper discusses a novel kriging technique that uses sparse irregularly spaced permeability data to generate permeability values at other points within chosen grid blocks. A uniquely designed computer program, expressed in FORTRAN provides solution to the sequence of algorithms required for the solution of the kriging system in the absence of more sophisticated kriging models. Results obtained from the model allows for relatively cheap and reasonably accurate characterization of heterogeneous reservoirs.
