1. A method for characterizing a subterranean formation traversed by a borehole and changing drilling operations based upon an updated reservoir model, the method comprising:
- providing or generating a reservoir model that represents the subterranean formation, wherein the reservoir model includes i) data representing geometry of the subterranean formation including at least one of a formation boundary, fault, or fluid contact, and ii) data representing properties of the subterranean formation;
generating an invasion object that stores information describing invasion of fluid surrounding the borehole drilled in a horizontal well, wherein the reservoir model uses a first scale and the invasion object uses a second scale that is larger than the first scale thereby providing more detail for the invasion object, wherein the invasion object comprises at least one invasion profile definition including an inside invasion shape and an outside invasion shape;
displaying, at a graphical user interface, at least a portion of the reservoir model at the first scale and the invasion object at the second scale that is larger than the first scale;
modifying, at the graphical user interface, the invasion object while displaying the reservoir model and the invasion object;
using a modified invasion object to update the reservoir model and generate an updated reservoir model; and
using, at least in part, the updated reservoir model to change drilling operations at the borehole.

Abstract
A method for characterizing a subterranean formation traversed by a wellbore includes generating a reservoir model using data collected from the formation, generating a perturbation object comprising a perturbation of the wellbore, integrating the perturbation object with the reservoir model, and forming a geological model wherein the perturbation object is integrated in the reservoir model.
