Automated contamination prediction based on downhole fluid sampling

A system to sample downhole fluid, the system comprising:

• a drilling rig comprising a bottom hole assembly disposed in a wellbore and configured to acquire fluid data;
• a processing system comprising a memory and a processor, the processing system being disposed at a surface of the wellbore, the processing system for executing computer readable instructions, the computer readable instructions controlling the processing system to perform operations comprising:
• receiving the fluid data from a fluid downhole in a wellbore operation;
• defining a subset of the fluid data and a remaining subset of the fluid data;
• iteratively generating a plurality of curves fit to the subset of the fluid data;
• and
• performing a validation on the plurality of curves as applied to the remaining subset of the fluid data to determine one or more best fit curves from the plurality of curves.
