... of the present work. GaStim concept is presented as a novel chemical stimulation technique potentially allowing deeper penetrations and better chemical adsorptions. Its potential, although still not fully undiscovered, is certainly supported by higher Ko reestablishment values and longer treatment durabilities...

... Abstract Gas-bearing shales are characterized by pore systems that are present in the organic (kerogen) matrix, inorganic matrix, natural fractures, and induced fractures. Each pore system has different physical properties. The organic matrix essentially has gas-wet nanopores with adsorptive...

... for adsorption ( Ambrose et al. 2011 ). Second, the pores in kerogen are on the order of nanometers in size, which creates a surface area orders of magnitude higher than the surface area of, for example, a piece of sandstone with the same volume and porosity ( Passey et al. 2010 ; Fathi and Akkutlu 2011...

... and adsorption. Standard approach to describe gas-matrix interactions is deterministic and neglects the effects of local spatial heterogeneities in porosity and material content of the matrix. In this work, adopting weak-noise and mean-field approximations and using a statistical approach in spectral domain...

... Abstract In design and implementation of Alkali Surfactant Polymer (ASP) formulation for IOR processes, the inorganic alkali component acts as sacrificing agent avoiding the surfactant adsorption and decreasing the IFT. Nevertheless, as a part of this process there are some potential problems...
