Predicting Contamination and Clean Fluid Properties From Downhole and Wellsite Gas Chromatograms

A method comprising:

• disposing a downhole fluid sampling tool into a wellbore at a first location, wherein the downhole fluid sampling tool comprises:
• at least one multi-chamber section;
• at least one fluid module section;
• and
• activating a pump to draw a solids-containing fluid disposed in the wellbore into the downhole fluid sampling tool;
• raising the downhole fluid sampling tool to surface;
• disposing the solids-containing fluid into a fluid analysis module;
• measuring the drilling fluid filtrate from the solids-containing fluid with a sensor disposed in the fluid analysis module to form data, wherein the data comprises sensor measurements from each of two or more samples, wherein the two or more samples comprise a mud filtrate and a formation fluid;
• inputting the data into an information handling system;
• forming a data matrix from the data;
• extracting one or more measurements of the mud filtrate and the formation fluid from the solids-containing fluid;
• extracting a concentration profile of the mud filtrate and the formation fluid;
• and
• decomposing a data set on an information handling machine using a model.

A system comprising:

• a downhole fluid sampling tool comprising:
• one or more multi-chamber sections;
• one or more fluid module sections;
• one or more sensors, wherein the one or more sensors are disposed in the one or more fluid module sections;
• and
• an information handling system configured to:
• form a data matrix;
• extract one or more measurements of a mud filtrate and a formation fluid from the downhole fluid sampling tool;
• extract a concentration profile of the mud filtrate and the formation fluid from the downhole fluid sampling tool;
• and
• decompose a data set with, D=CST+E, wherein D is the data matrix, C is the concentration profile of the mud filtrate and the formation fluid, S is the one or more measurements of the mud filtrate and the formation fluid, T is a transpose of matrix S, and E is error.
