Although there are many details,the workflow for developing the Hugoton geomodel can
be described simply in four steps:1)define interval tops from logs,lithofacies in core,
petrophysical properties for lithofacies,and accurate log correction algorithms to obtain a
log database,2)train a neural network and predict lithofacies at node wells,3)populate a
3D cellular model with lithofacies using stochastic methods and porosity,and 4)populate
model with lithofacies-specific petrophysical properties and fluid saturations.Figure 6.1
provides a more comprehensive overview.Following is a discussion of each of the steps
for integrating core-defined lithofacies,core-derived petrophysical properties,wireline
log response,and prediction of reservoir properties to characterize the reservoir system at
the core-and well scale,and at the field scale.
