... Abstract In Teklu et al. (2017a , and 2017b ) matrix and fracture permeability of carbonate rich and clay rich shale cores were measured before and after exposing the core samples to spontaneous dilute acid imbibition. In this study, effect of brine and dilute acid imbibition on long term...

... challenges for operators to adopt mechanical and chemical water treatment means to remove impurities from flowbacks for reuse in slickwater fracturing. However, most treatments do not remove brines from the water requiring development of high brine tolerant friction reducer to maintain high performance...

... distilled water into the transfer vessel, then pump the test liquid (crude oil or Soltrol 130 oil) into the transfer cylinder. For the brine experiments, add another transfer cylinder (that contains brine) after the oil transfer cylinder. In this way, distilled water from the ISCO pump drives oil from...

... space in the reservoir at irreducible saturation conditions. This paper presents the steady-state brine-CO 2 relative permeability measurements in a sandstone core under CO 2 flooding conditions versus pressure and temperature. The results indicate a strong correlation between pressure...

... Abstract Recent studies involving the measurement of friction reducer performance with a variety of brines typical of flow back/recycled stimulation waters of the North Eastern United States have indicated a clear differentiation by specific product type. The friction reducer variances...

... or surface discharge (Weatherford Telegram 2007). What to do with the post-frac flowback waters in the light of scarce brine disposal facilities and substantial handling costs is an enormous burden to the economic development of the Marcellus natural gas resource.

... Abstract A major concern of any hydrocarbon producer is the production of brine. Since the brine is potentially environmentally hazardous certain legal guidelines for its disposal must be followed. The current process is to inject it into an empty reservoir. However, the problem of increasing...

... analyzed and deemed representative of the Rose Run Sandstone. Rotary sidewall cores were tested to determine initial permeability to Rose Run formation brine and regained permeability to various acid solutions. The results of all analyses were considered in revising initial well stimulations as well...

... ABSTRACT Stripper wells generally produce formation brine along with oil. In order to meet the discharge criteria established by federal and state environmental agencies, and to sustain continued production from these marginally economic wells, this brine must be treated in a cost-effective...

... sandstone cores were placed in horizontal position with their flood planes parallel to their bedding planes and oil displaced from them by brine at injection rate ranging from 1.20 cc/min to 7.90 cc/min.
