ABSTRACT
Innovative modeling techniques
were combined to generate a quantitative, realistic characterization of
the eolian Jurassic Nugget Sandstone for an ongoing reservoir study. Dimensions
of four different eolian stratification types, infilling cross-set frameworks
derived from synthetic bed-form modeling, provided statistical parameters
for conditional simulations . Permeability fields generated in the conditional
simulation were scaled up for flow simulation in cross section and three-dimensional
models. Sensitivities to geologic uncertainties and to conditional simulation
parameters were studied. A representative geologic model, with appropriate
delineation of reservoir heterogeneity for this field , was attained by
matching historical performance of a field segment. |
