PH monitoring in porous media during waterflooding experiments

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.
