... the performance of surfactants and water alone. Finally, laboratory data are used in numerical simulation to model laboratory results and upscale these findings to the field. The results showed that aqueous solutions with surfactants altered rock wettability from oil-wet and intermediate-wet to water-wet...

... to quantify the different types of porosity, the NMR T 2 spectra of 5 Barnett shale samples have been acquired, both in their native state, after dodecane saturation at 3000 psia, and after immersion in a 65% MnCl 2 aqueous solution. These NMR spectra were acquired with Tau = 57 μsec on a 2MHz instrument...
