A method for determining interfacial tension of a hydrocarbon in a brine fluid, the method including injecting a first brine fluid into a test cell, the first brine fluid having an initial ionic composition, injecting a hydrocarbon fluid into the test cell, contacting the hydrocarbon fluid with the first brine fluid, forming a droplet, measuring the interfacial tension of the hydrocarbon fluid in contact with the first brine fluid, at least partially displacing the first brine fluid with an inert gas, measuring a ionic composition salinity of the displaced first brine fluid in an ionic chromatograph, and comparing the measured ionic composition salinity to the initial ionic composition.

The longitudinal relaxation times (T) of water and hydrocarbon inside porous media, such as rock from subsurface formations, behave differently when external magnetic fields vary. A Nuclear Magnetic Relaxation Dispersion (NMRD) profile from Fast Field Cycling Nuclear Magnetic Resonance (FFC-NMR) technique differentiates the type of fluids filling the pores. Different types of pores in a rock sample are filled with different fluids, water and hydrocarbon, and the absolute porosity and the pore size of each type of pores is determined.

Absolute porosity and pore size determination of pore types in media with varying pore sizes

A method for increasing oil production in a carbonate reservoir by incorporating a saline solution injection including a saline soluble surfactant and a saline soluble polymer. The method provides for increased oil production as compared to conventional waterflooding techniques.

The connectivity between different pore types in porous media is measured by using low-field nuclear magnetic (NMR) and fast field cycling NMR techniques. Due to the fluid exchange between connected pores, T(T) NMR relaxation times of proton nuclei of fluids in the different pore types are shifted. By comparing the T(T) NMR relaxation times of porous media samples which are 100% brine saturated with relaxation times for the samples containing brine and hydrocarbon in the different pore systems of the samples, the connectivity between the pores can be measured.

The present invention relates to a method for determining trace amounts of crude oil in water, including the steps of collecting a sample of an oil-containing fluid, adding a toluene extraction volume to the sample, perturbing the sample, dissolving substantially all of the amount of oil in the toluene extraction volume to create a mixed sample, extracting the mixed sample to create an oil-in-toluene layer and an aqueous fluid layer, removing a portion of the oil-in-toluene layer into a dilution container, diluting the portion of the oil-in-toluene layer with a toluene dilution volume to create a dilute sample, measuring an absorption value of the dilute sample using a spectrophotometer, and comparing the absorption value to a calibration curve to quantify the amount of oil in the oil-containing fluid.
