Abstract
A method for performing a field operation within a geologic basin having rock formations and a reservoir that includes fluids includes generating, by forward modeling using a petroleum system model (PSM), an estimate of a fluid property distribution of a fluid within the reservoir of the geologic basin. The method further includes detecting, from fluid samples, a fluid property gradient within the geologic basin. The fluid samples are extracted from within at least one wellbore drilled through the rock formations. The method further includes, comparing the estimate of the fluid property distribution with the detected fluid property gradient to generate a comparison result, iteratively adjusting, based on the comparison result, the PSM to generate an adjusted PSM, and performing, based on the adjusted PSM, the field operation within the geologic basin.
