Cleanup prediction and monitoring

A method, comprising:

• predicting cleanup of a sample fluid obtained by a downhole tool by:
• displaying a plurality of model parameters via a graphical user interface;
• receiving user inputs via the graphical user interface to set respective values for each of the model parameters;
• processing the values using a lookup table to generate a curve representing a decreasing contamination level of the sample fluid, the lookup table including data generated via a plurality of numerical modeling simulations performed prior to the processing of the values;
• and
• displaying the curve via the graphical user interface.

An apparatus, comprising:

• a downhole tool configured for conveyance within a wellbore extending into a subterranean formation, wherein the downhole tool is further configured for predicting cleanup of a sample fluid obtained by a downhole tool, and wherein the downhole tool comprises:
• a memory storing lookup table data, the lookup table data comprising data associated with simulations based on a fluid transport model;
• and
• a processing unit to receive a plurality of fitting points, each of the fitting points corresponding to a respective measured optical density of the sample fluid, and to receive one or more inversion parameters, each of the received inversion parameters corresponding to a parameter of the fluid transport model, wherein the processing unit is to perform an inversion using the fitting points and the inversion parameters to generate data associated with a predicted cleanup of the sample fluid.
