Abstract This paper describes the development of a highly automated apparatus and customized software package to rapidly evaluate the performance of surfactant additives in dry gas shale reservoirs. A major challenge throughout the industry is the ability to reduce water saturation resulting...

... Abstract Slickwater has been widely used for hydraulic fracturing as it is inexpensive and able to carry proppants into the fracture. However, such fluid is unsuitable for water-sensitive formations, such as Montney. Water saturation around the fracture increases and clay swells when water...

A tight gas reservoir is a low permeability reservoir of less than 0.5 md which tends to have higher capillary pressure and higher irreducible water saturation than a conventional reservoir.
