Tigress Mapping allows geoscientists to model the structural and
lithological properties of reservoirs spatially. Geophysical,
geological and petrophysical data can be integrated to construct an
accurate reservoir volumetric model. Complex arithmetic or logical
operations can be performed on data using standard or user defined
equations, the results of which can be used in the volumetric
model. Volumetric calculations can be performed on the model with
results being reported in a choice of units and on an area by area
basis. The static model can be passed to Tigress
Simulation as the basis for the fluid flow simulation
model.
