Paper Number: URTEC-2020-2947-MS
... Abstract Scope/Objective : The advent of the shale boom has motivated many oil and gas companies to venture into different types of shale plays including the Caney Shale. Historically, the Caney Shale was evaluated as a seal rather than a reservoir, which resulted in few studies...

... Abstract Shale-fluid interaction is a source of wellbore instability and inadequate stimulation performance in clay-rich shale formations such as Tuscaloosa Marine Shale which is the subject of this study. Moreover, shale formations usually exhibit significant fine-scale heterogeneity while the...
