... using tight sandstone show that hydrophobic wettability function on the sandstone surface, making a contact angle greater than 90°. The inner wall of capillary tube changes wettability and the capillary pressure becomes a positive driving force rather than a negative resistance. The experimental studies...

Paper presented at the PAPG/SPE Pakistan Section Annual Technical Conference and Exhibition, November 21–23, 2016
Paper Number: SPE-185308-MS
... Similar results were found for medium TOC shale except that at any pressure and temperature, lower values of contact angles were found for medium TOC shale. Thus it implies that high TOC shale are more CO 2 -wet than medium TOC shale (or medium TOC shale are relatively better water-wet than high...
