Fluid property modeling that employs a model that characterizes asphaltene concentration gradients is integrated into a reservoir modeling and simulation framework to allow for reservoir compartmentalization (the presence or absence of flow barrier in the reservoir) to be assessed more quickly and easily. Additionally, automated integration of the fluid property modeling into the reservoir modeling and simulation framework allows the compositional gradients produced by the fluid property modeler (particularly asphaltene concentration gradients) to be combined with other data, such as geologic data and other petrophysical data, which allows for more accurate assessment of reservoir compartmentalization.

Method and systems for reservoir modeling, evaluation and simulation

A system and method for optimizing a drilling operation is provided. The system has a drilling a drilling operation optimization unit. The drilling operation optimization unit has a base model unit for producing a base model of the reservoir and a reservoir stress unit for producing a three dimensional stress model of the reservoir. The drilling operation optimization unit has a trajectory unit for determining at least one property for at least one wellbore trajectory based on the base model and the three dimensional stress model, wherein each of the wellbore trajectories is selectable by an operator. The system has an operator station for inputting data into the drilling operation optimization unit at the wellsite and a drilling tool for forming a wellbore along at least one of the at least one selected wellbore trajectories.
