Organic petrography via incident light microscopy has broad application to shale petroleum
systems, including delineation of thermal maturity windows and determination of organo …

While there is a consensus in the literature that embracing nanodevices and nanomaterials
helps in improving the efficiency and performance, the reason for the better performance is …

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 …

This paper aims at characterizing the inorganic and organic pore size distribution (PSD
inorg and PSD org) of gas shale samples. To achieve this goal, we first perform nitrogen (N …

The petrographic study of organic matter (OM) in fine-grained, shale and tight rocks can be
complicated by ambiguities in distinguishing primary kerogen (deposited OM) from …

In this paper, we experimentally investigate the possibility of formation damage reduction
during leak-off and flowback processes by adding surfactants to the fracturing fluid. The …

The variation in pore water distribution within gas shale reservoirs has a significant effect on
gas content, and thus on resource evaluation. However, the characteristics of water micro …

The understanding of the mechanisms that govern spontaneous water imbibition in gas-
water systems plays a significant role in operating the hydraulic fracturing and the …

Horizontal wells with hydraulic fractures in tight oil reservoirs show producing-gas/oil-ratio
(GOR) behavior that is very different from conventional, higher-permeability reservoirs. This …

Many naturally occurring porous media contain different types of grains with different
wettabilities, therefore, understanding the effect of wettability heterogeneity on multiphase …
