Investigating Influential Factors of the Gas Absorption Capacity in Shale Reservoirs Using Integrated Petrophysical, Mineralogical and Geochemical Experiments: A Case Study The results showed that in shale reservoirs with high maturity and high organic content that the adsorbed gas volume increases, with an increase in the contents of organic matter and

Experimental Study and Numerical Modeling of Fracture Propagation in Shale Rocks During Brazilian Disk Test

To incorporate the effects of shale formation heterogeneity in the simulation of crack paths, fracture properties of the specimens are defined as spatially random fields. A computational strategy on the basis of stochastic finite element theory is developed that allows to incorporate the effects of heterogeneity of shale rocks on

Numerical Simulation of Fracking in Shale Rocks: Current State and Future Approaches, PART 3

Fig. 15 Configurational force crack (from [129])

8.1 Definitions The peridynamics formulation was first developed by Silling [248], where he tried to overcome the limitation of current theories dealing with discontinuity, such as in fracture mechanics problems. The main argument was that the difficulty of existing theories was due to the presence of partial derivatives in the formulation

Confined Phase Envelope of Gas-Condensate Systems in Shale Rocks

This paper describes the complex phenomena related to the impact of adsorption and capillary condensation of gas-condensate systems in nanopores. New two phase saturation model and new algorithm for search capillary condensation area is discussed.

Confined Phase Envelope of Gas-Condensate Systems in Shale Rocks   STANISLAW NAGY*, JAKUB SIEMEK*   AGH UNIVERSITY OF SCIENCE & TECHNOLOGY, DRILLING & OIL-GAS FACULTY, AL. A. MICKIEWICZA 30, 30-059 KRAKOW, POLAND. Abstract Natural gas from shales (NGS) and from tight rocks are one of the most important fossil energy resource in this and next decade.
