Abstract
A method is provided including calculating a first property vector indicative of physical properties derived from a digital image of a first rock sample; determining a set of one or more similar rock samples by calculating a value indicating a similarity between the first rock sample and second rock samples based on the first property vector and second property vectors associated with the second rock samples; selecting a list of fluid additives based on existing enhanced fluid recovery efficiency values associated with the similar rock samples; performing, for each of the fluid additives, a simulation of a flow of fluid through a digital model of the first rock to determine a simulated enhanced fluid recovery efficiency value for the respective fluid additives; and outputting an optimal fluid additive for the first rock sample based at least in part on the calculated similarity values and simulated enhanced fluid recovery efficiency values.
