Gaussian collocated cosimulation

1. n. [Reservoir Characterization]
An algorithm built on a Markov-type hypothesis, whereby collocated secondary information is assumed to screen out secondary data from farther away. The method allows the direct cosimulation of several interdependent variables, integrating several different sources of soft information.
