Paper Number: SPE-168968-MS
... increasing attention in recent years. The Eagleford Shale in the U.S. and the Duvernay Shale in Canada are examples of liquid-rich shale gas plays which are being exploited to produce more profitable liquid hydrocarbons with natural gas. These reservoirs may store liquid hydrocarbons in liquid or vapor state...

... the organic matters where the pore sizes are in the order of nanometer scales. Inside these nanopores, the interactions between the fluid molecules and porous walls play such an important role that can change the phase behavior as well as transport mechanisms of the hydrocarbon fluids. For a shale gas...

.... The MS matching provides new information on spacing and aperture width of fractures in a network. Using a model for proppant spreading built around this information should help operators optimize proppant transport in shale gas and oil wells, to retain a larger SRV, and greater permeability enhancement...

... of up to 12,000 psi. These pressures are uniquely high among shale gas reservoirs, and require special treatment. We show that the methods developed by Patzek, et al., PNAS, 110, 19731-19736, can scale all individual wells' gas productions to fit upon a single, universal curve. Haynesville wells can...

... deviations from their bulk behavior. This is due to the significant effect of molecule-wall interactions as well as molecule-molecule interactions in shale formations which are mainly characterized by nanopores. Consequently, production from shale gas reservoirs is strongly influenced by pore sizes...

... technologies, production rates and economics of shale gas wells have significantly improved ( East et al. 2004 ; Ketter et al. 2006 ). Abstract Since 2008, the Eagle Ford Shale has been one of the most active U.S. oil and gas plays. Regional variations of the frequency (cyclicity) and thickness...

... Abstract Tight oil and shale gas resources produced 29% of total US crude oil and 40% of total US natural gas in 2012 (EIA). Technically recoverable quantities of shale gas and shale oil resources for the US are 665 trillion cubic feet and 58 billion barrels, respectively. Considering...

... Abstract Although existing models for analysing single-phase flowback water production at the onset of flowback in tight oil and gas reservoirs provide estimates of fracture volume, they are not applicable to shale gas reservoirs. This is because flowback data from shale gas wells do not show...

The idea of statistical approach was further developed and was the basis of statistical reverse model (SRM) for mineralogy and organic matter interpretation of shale-gas reservoirs ( Jenson and Rael, 2012 ). The statistical reverse model, incorporating the random errors of logging, can solve...
