TL;DR: In this paper, the authors provide an overview of the challenges associated with evaluating key reservoir and hydraulic fracture properties and discuss recent advances in the area of shale gas reservoir and fracture characterization.

TL;DR: In this paper, micro-contact angles were estimated by extracting sessile droplet profiles with user-guided software developed in-house and then fitting a parameterized Young-Laplace equation to the profile.

TL;DR: For the first time, live imaging of fluids injected through a micro-injection system has enabled quantification of sessile and dynamic micro-droplet contact angles at the micro-scale, calling into question the applicability of macro-scale observations of fluid-rock interaction.

TL;DR: In this article, a new theoretical model was developed to characterize the corresponding wetting dynamics of nanoliter water droplets in nanoporous media, and it was demonstrated that even for an intrinsically hydrophobic nanoporous substrate, spontaneous imbibition of a noliter droplet can occur if capillary condensation had occurred internally already.

TL;DR: This study demonstrates that micro‐FTIR mapping is a valuable tool for studying shale heterogeneity on a micrometre to millimetre scale that becomes even more powerful in combination with scanning electron microscopy techniques, which extend observations to a nanometre scale.
