... Abstract To achieve economic production from shale gas reservoirs hydraulic fracturing is required. This stimulation technology facilitates the interconnection of the multiple pore systems with the wellbore. Particularly, shale gas reservoirs exhibit a dual porosity system linked to the free...

... Abstract Unconventional shale gas reservoirs around the world have been proven to store gigantic volumes of natural gas. It has been demonstrated with both laboratory and mathematical work that these reservoirs can be represented by a quintuple porosity formulation plus an additional storage...

In this paper, numerical reservoir simulation techniques, validated by field production data from Marcellus Shale, are employed to model the proppant distribution and geomechanics effect. A series of reservoir...

... Abstract Uncertainties in basic petrophysical parameters in shale gas reservoirs are discussed in this paper. These parameters include porosity, permeability, gas adsorption, water saturation and TOC. Current available methods to evaluate shale gas petrophysical properties are summarized...

... Abstract Numerical simulations are commonly used for studying and forecasting the production from conventional reservoirs. However, limitations of the Darcy’s equation have been noted for shale gas reservoirs due to the complexities associated with nano-scale pores, organic-rich heterogeneous...

... illustrate that Knudsen diffusion is not suitable for shale gas reservoirs. This is because Knudsen number is generally less than 10, especially for such shale gas reservoirs with higher initial reservoir pressure. Gas moving through shale matrix pores to fractures is mainly divided into two forms...

... Abstract Latest advances in shale gas reservoir simulation and modeling have made it possible to optimize and enhance the production from organic rich shale gas reservoirs. Reservoir simulator is no longer used with a simple description of the complex shale gas reservoirs, but with multiple...

... analyses indicate that shale heterogeneity (natural fractures/custers and organics spots) is a favorable characteristics of shale gas reservoirs because they contribute to the initial and long-term well productivity. Shale gas reservoirs without natural fractures/clusters will not produce natural gas...

... will present one simple analytical model based on the solution of the pseudo steady state equation and will introduce the concept of a shale gas normalized production plot. In our view, the shale gas normalized production plot is one type curve generally applicable to any shale gas reservoir. Finally, pre...
