System and method for estimating reservoir fluid contamination

Abstract

A system and method for determining reservoir fluid contamination of a reservoir is disclosed. The system includes one or more sensors to detect field measures from reservoir fluid of the reservoir and includes memory and at least one processor to execute instructions from the memory to cause the system to perform further steps. A step by the at least one processor is to simulate relationship data having purity levels correlated to volumes or times associated with extraction of an applied or simulated fluid for varying modeled rock formations. A further step is to fit one or more of the relationship data to the field measures to generate errors. Yet another step is to determine the reservoir fluid contamination from one of the purity levels that is associated with the relationship data that is within a threshold error value or error range of the errors.
