The present work provides the technique to determine the properties and quantify the concentration of expandable clay minerals, thus predicting the swelling potential of clay-rich rocks. A collection of ash layer and bentonite mine samples has been analyzed for the bulk and clay fraction mineral...

... effects of high TDS and temperature in Marcellus Shale formation. Anionic HVFRs at 4, 6, and 8 gallons per thousand gallons (GPT) were selected and analyzed. The rheology measurement of different concentrations of anionic HVFRs were conducted with deionized (DI) water, high TDS Marcellus Shale formation...

TDS up to concentrations of 275,000 ppm were evaluated and showed no impact on cationic FR performance, while anionic FR performance was significantly inhibited by 100,000 ppm. A capillary suction time test demonstrated that cationic...
