Unconventional natural gas has become an important source of energy. However, the
development of such resources has been challenging as these reservoirs are characterised …

Understanding water uptake of gas shales is critical for designing fracturing and treatment
fluids. Previous imbibition experiments on unconfined gas shales have led to several key …

We document vertical permeability of 2.3 * 10^-21\, m^ 2 2.3× 10-21 m 2 (2.3 nd) and
horizontal permeability of 9.5 * 10^-20\, m^ 2 9.5× 10-20 m 2 (96.3 nd) in two Barnett Shale …

Three laboratory methods were developed to measure matrix gas permeability (Km) of
Devonian shale cores and drill cuttings at native water saturations. The first method uses …

The research team conducted an extensive, multidisciplinary review of wastewater handling,
treatment, reuse and disposal as they relate to hydraulic fracturing by comparing the …

Various types of sediments and rocks were analyzed for the relationship between hydraulic
conductivity (K) and scale of measurement No variations of K with scale were observed for …

In this study, we investigate the role of clays on water sorption (adsorption and desorption)
behaviour of gas shale samples. First, we conduct conventional sorption experiments on …

Gas shales have become an important resource for the production of hydrocarbons in North
America, and are being explored as a resource on other continents as well, based on their …

The combined application of multi-lateral horizontal drilling and multi-stage hydraulic
fracturing has successfully unlocked unconventional tight hydrocarbon reservoirs. However …

Field studies demonstrate low flowback efficiency determined by volumetric analysis of
injected and recovered fracturing water. However, the reasons for inefficient water recovery …
