... with clear brine. However, conventional filter cake breakers demonstrated poor performance in removing filter cake from Reservoir Drill-in Fluid (RDF). This underperformance was attributed to their inability to fully remediate near-wellbore damage, particularly in the open-hole production section. Key...

... Abstract The zero liquid discharge approach, by recovering water and dissolved valuable salts, is the most attractive clean technology for valorizing brines from low salinity brines like seawater, using desalination reverse osmosis (SWD-RO) plants. In the case of current technology, a key...

... a challenge due to their unique solubility in brine under most of the reservoir conditions. The reliability of static surfactant adsorption tests is questionable, especially for switchable amine surfactants, because the testing conditions greatly deviate from the reservoir conditions. For the first time...

... Abstract This study comprises an experimental investigation and comparison of different brine compositions for waterflooding applications in carbonate reservoirs. In particular, a novel zero liquid discharge (ZLD) brine, which is obtained from produced water treatment and features...

..., friction reduction, and flow-back performance. Hydration time of the DFRs in synthetic brine was measured by viscosity monitoring. The viscosity was measured using rheometer at 160°F. Friction reduction of DFR samples was characterized by industry standard friction flow loop system. Formation damage...

... Abstract Polymeric scale inhibitors (SIs) possess excellent dispersive and scale inhibition properties. In this study, a series of phosphorous-tagged polymeric SIs (PPSIs) were synthesized to inhibit calcium scale formation in synthetic brines. The design of chemical structure followed previous...

Polymers were evaluated at the reservoir temperature (i.e. 190°F / 88°C) using brine with a TDS and divalent cations concentration of ~260,000 ppm and 19,000 ppm, respectively. For such conditions, data...

... water issue was addressed by replacing the environment with 5% potassium chloride (KCl) brine and using 30% excess cement with coiled tubing. Moreover, acid-soluble cement was used to protect the water-free reservoir such that if cement is lost, acid can help to dissolve it. With comprehensive...

... Abstract The subsurface processes of enhanced oil recovery (EOR) and carbon capture and storage (CCS) involve complex geochemical interactions mainly CO 2 , brine, and reservoir rock. This interaction is time-dependent and could influence the wettability and thus the multiphase flow. Less...
