Method ans systems for reservoir modeling, evaluation and simulation

A software framework executable on a computer processing system for evaluating a subterranean formation, the software framework comprising:

• a geological modeler that derives a first model of the formation, the first model representing rock properties as a function of location in the formation;
• a fluid property modeler that derives a second model of the formation, the second model representing fluid properties as a function of location in the formation, wherein the fluid properties of the second model characterize asphaltene concentration as a function of location in the formation;
• and
• a module for deriving a reservoir simulation model of the formation, the reservoir simulation model including rock properties as a function of location in the formation that are based on the rock properties of the geological model, and the reservoir simulation model also including fluid properties as a function of location in the formation that are based on the fluid properties of the fluid property model, wherein the fluid properties of the reservoir simulation model characterize asphaltene concentration as a function of location in the formation.
