Abstract: Systems and methods for improving injectivity of a hydrocarbon reservoir include: identifying a restriction of flow from an injection well into the hydrocarbon reservoir; transmitting a series of acoustic waves from an injection well into a formation that includes the hydrocarbon reservoir, wherein the series of acoustic waves are transmitted continuously for at least one day; transmitting a series of seismic waves from the injection well into the formation after the series of acoustic waves are transmitted into the hydrocarbon reservoir, wherein the series of seismic waves are transmitted continuously for at least one week; and injecting water into the injection well to cause hydrocarbon of the hydrocarbon reservoir to flow from the hydrocarbon reservoir to a production well after the series of acoustic waves are transmitted into the hydrocarbon reservoir.

Abstract: Methods and systems are provided for measuring the zeta potential of macroscopic solid surfaces including and not limited to: porous samples, flat substrates, coarse particles, and granular samples. Methods include: subjecting the sample to an injection of a first aqueous solution at an initial pressure with an initial ion concentration; measuring a first electrical conductivity and a first temperature of the first aqueous solution; measuring a first pH and a second pH of the first aqueous solution immediately before and after passing the first aqueous solution through the sample; measuring a first ion concentration and a second ion concentration of the first aqueous solution immediately before and after passing the first aqueous solution through the sample; and processing the measured data to derive a first zeta potential from the first electrical conductivity and the first temperature.

Abstract: An oil recovery composition of an aqueous solution of one or more salts and dilute polymer and processes for enhanced oil recovery using the oil recovery composition are provided. An oil recovery composition may include an aqueous solution of one or more salts having a salinity of about 4000 parts-per-million (ppm) total dissolved solids (TDS) to about 8000 ppm TDS and a polymer having a concentration of 250 ppm to 750 ppm. The one or more salts may include at least one of sodium chloride (NaCl), calcium chloride (CaCl2), magnesium chloride (MgCl2), sodium sulfate (Na2SO4) and magnesium sulfate (MgSO4). The polymer may include a copolymer of acrylamide and acrylamido tertiary butyl sulfonate (ATBS). The oil recovery compositions provided may be suited for enhancing oil recovery in carbonate reservoirs having in situ oil viscosities less than 3 centipoise (cP).
