Abstract
An apparatus is operated to obtain a model predicting data associated with a theoretical sampling operation to be performed by a downhole sampling tool, including predicted water-cut and pressure data relative to time elapsed during the theoretical sampling operation. The model predicts the water-cut and pressure data based on estimated relative permeability and capillary pressure related to different constituents of fluid theoretically obtained from a subterranean formation by the downhole sampling tool during the theoretical sampling operation. An actual sampling operation is performed with the downhole sampling tool to actually obtain fluid and data associated with the actually obtained fluid, including actual water-cut and drawdown pressure data. The apparatus is then operated to update the model utilizing the actual data water-cut and drawdown pressure data, thus obtaining actual relative permeability and capillary pressure data.
