Abstract: Provided is a coreflood system that comprises a housing including an inlet end and an outlet end, an inlet positioned at the inlet end, and an outlet positioned at the outlet end. The system includes two chambers positioned within the housing between the inlet and the outlet, configured to retain porous media. The two chambers are in series along a fluid flow pathway through the coreflood system. The system includes a partition extending from an inner surface of the housing between the inlet and the outlet, and a pH sensor provide in a sensor mounting location in the housing having access to the fluid flow pathway. Further provided is a method that comprises directing a fluid into a coreflood system, and using a data processing device coupled to the pH sensor to collect hydrogen ion data and determine hydrogen ion concentration and pH within the fluid.

Abstract: A process for the preparation and imaging of a sample of rock from an oil and gas reservoir is provided. A sample of reservoir rock may be obtained, such as from a core sample obtained using a core sampling tool inserted in a wellbore extending into an oil and gas reservoir. A photoresist may be deposited on the surface of reservoir rock sample to form a homogenous layer. The photoresist-coated surface of the reservoir rock sample may be imaged using a focused ion beam (FIB). The photoresist protects the pores and other surface features of the rock from damage or implantation by the FIB ion beam and thus minimizes the curtain effect in the resulting images.

Abstract: Systems and methods for supplying water to a hydrocarbon-containing formation may include generating artificial rain in the proximity of the formation and collecting the artificial rain in one or more collectors. Following collection, the artificial rain may be transferred from the one or more collectors to an underground water reservoir. The artificial rain may then be combined with an aqueous fluid to give a wellbore fluid, which may then be transferred or injected into the wellbore.

Abstract: A method includes flowing an inlet solution having an inlet salinity and an inlet ion concentration from an inlet to a membrane filtration system, dynamically adjusting the salinity or ion concentration of the inlet solution in situ as the inlet solution flows to an inlet of a microfluidic cell, and determining a wettability alteration in situ while dynamically adjusting the salinity or ion concentration of the inlet solution. A system includes a fluid inlet, a microfluidic cell fluidly coupled to the fluid inlet, the microfluidic cell having a surface representative of a reservoir rock, and a membrane filtration system coupled between the microfluidic cell and the fluid inlet.
