The shale boom in North America started more than a decade ago, however, the issue of
substantial fracturing fluid loss inside shale did not draw much attention for a decade. In the …

Nanoparticle dispersions at a minute concentration in salt mixtures have recently been
reported to significantly increase their specific heat capacity. However, there is a …

Despite the success of hydrocarbon production from unconventional shale reservoirs, the
understanding of shale wettability under in-situ conditions remains a challenge. Shale …

Characteristics of water film thickness and stability within nanopores are topics of great
interest for evaluation of initial fluid storage in unconventional reservoirs. Although related …

Wettability alteration exhibits a significant potential to improve the oil recovery of shale
reservoirs by means of spontaneous imbibition through shifting the rock wetness from oil-wet …

The low recovery of hydraulic fracturing fluid in unconventional shale reservoirs has been in
the centre of attention from both technical and environmental perspectives in the last …

Characteristics of sorption and distribution of water in nanoporous shale are topics of great
interest to evaluate unconventional reservoirs. Also, a study of surface force of water/solid …

Tight hydrocarbon reservoirs require stimulation to improve the recovery of oil and gas
resources. Hydraulic fracturing is a technique extensively employed in the oil and gas …

In this study, we conduct spontaneous imbibition tests and measure air-oil and air-brine
contact angles of nine twin core plugs from five wells drilled in the Duvernay Formation …

Hydraulic fracturing is typically required before shale gas production. Residual fracturing
fluid in the reservoir leads to a hydration reaction and weakens the fracturing effect. To …
