Methods for developing equation-of-states (EOS) composition models for predicting petroleum reservoir fluid behavior and understanding fluid heterogeneity in unconventional shale plays are described. In particular, limited geochemical data from samples taken from the reservoir of interested are utilized to build and tune the EOS model and improve predictions. Real-time applications are also described.

Phase predictions using geochemical data

The present invention includes compositions and methods for treating a hydrocarbon-bearing formation by contacting the hydrocarbon-bearing formation with a fluid that includes at least one of a polyol or polyol ether, wherein the polyol and polyol ether independently have from 2 to 25 carbon atoms; and at least one of a monohydroxy alcohol, ether, or ketone, wherein the monohydroxy alcohol, ether, and ketone independently have from 1 to 4 carbon atoms, and wherein the at least one of a polyol or polyol ether is present in the fluid at at least 50 weight percent, based on the total weight of the fluid.

Method for treating a formation with a solvent

This invention relates to enhanced oil recovery methods to improve hydrocarbon reservoir production. An enhanced oil recovery screening model has been developed which consists of a set of correlations to estimate the oil recovery from miscible and immiscible gas/solvent injection (CO, N, and hydrocarbons), polymer flood, surfactant polymer flood, alkaline-polymer flood and alkaline surfactant-polymer flood.

Enhanced oil recovery screening model

The present invention includes a method for treating a hydrocarbon-bearing clastic formation having brine. The method includes contacting the hydrocarbon-bearing clastic formation with a fluid, which at least one of at least partially solubilizes or at least partially displaces the brine in the hydrocarbon-bearing clastic formation, and subsequently contacting the hydrocarbon-bearing clastic formation with a composition. The composition includes a nonionic fluorinated polymeric surfactant and solvent. When the composition is contacting the hydrocarbon-bearing clastic formation, the nonionic fluorinated polymeric surfactant has a cloud point that is above the temperature of the hydrocarbon-bearing clastic formation.

Methods for treating a formation having at least one fracture using a composition containing a nonionic polymer and solvent. Methods for making a composition for treating a clastic formation bearing brine and at least one of black oil or volatile oil.

Methods for improving the productivity of oil producing wells

The present invention includes a method of treating a hydrocarbon-bearing clastic formation having non-connate water by contacting the hydrocarbon-bearing clastic formation with a composition that includes a solvent and a nonionic fluorinated polymeric surfactant wherein the solvent at least partially displaces or solubilizes the water in the formation.

Compositions and methods for treating a water blocked well using a nonionic fluorinated surfactant

The present invention includes compositions and methods of treating a hydrocarbon-bearing formation, the formation having at least one fracture, by contacting the fracture with a composition that includes a solvent and a nonionic fluorinated polymeric surfactant, wherein the composition interacts with at least a portion of the proppants in the fracture.
