Retention of Hydraulic Fracturing Water in Shale: The Influence of Anionic Surfactant However, the role of some surface active agents like surfactants that are added in the hydraulic fracturing mixture in this issue needs to be understood. In this study, the influence of Internal Olefin Sulfate (IOS), which is an anionic

Integrating Embedded Discrete Fracture and Dual-Porosity, Dual-Permeability Methods to Simulate Fluid Flow in Shale Oil Reservoirs
Integrating Embedded Discrete Fracture and Dual-Porosity, Dual-Permeability Methods to Simulate Fluid Flow in Shale Oil Reservoirs Most previous simulation studies have been based on dual porosity, but simulation results from dual-porosity models have not been as accurate as discrete fracture models in composition modeling. This study proposes a new model that integrates
A Prediction Model for Methane Adsorption capacity in Shale Gas Reservoirs
A Prediction Model for Methane Adsorption capacity in Shale Gas Reservoirs The model was established in four steps: a model of Langmuir volume at experimental temperature, the temperature dependence of Langmuir volume, a model of Langmuir pressure, the temperature dependence of Langmuir pressure. In the model of Langmuir volume at experimental
Imbibition — the “old all new”production mechanism of shale gas and oil
Imbibition --- the "old all new"production mechanism of shale gas and oil Conventional oil and gas production mechanisms Such conventional transport mechanism is well understood and also believed to be the dominant transport mechanism in shale gas and oil production. Under such conventional production mechanism, it is widely accepted that there is the
Numerical and Experimental Investigations of the Interactions between Hydraulic and Natural Fractures in Shale Formations
Numerical and Experimental Investigations of the Interactions between Hydraulic and Natural Fractures in Shale Formations The inelastic deformation, e.g., stick, slip and separation, of the geologic discontinuities is captured by a special friction joint element called Mohr-Coulomb joint element. The dynamic stress transfer mechanisms between the two fracture systems and the
Science of Carbon Storage in Deep Saline Formations: Process Coupling across Time and Spatial
Science of Carbon Storage in Deep Saline Formations: Process Coupling across Time and Spatial Editors: Pania Newell & Anastasia G. Ilgen Abstract: Science of Carbon Storage in Deep Saline Formations: Process Coupling across Time and Spatial Scales summarizes state-of-the-art research, emphasizing how the coupling of physical and chemical processes as subsurface systems re-equilibrate during
Methods of Decline Curve Analysis for Shale Gas Reservoirs

Methods of Decline Curve Analysis for Shale Gas Reservoirs In this article, the eight most popular deterministic decline curve methods are reviewed: Arps, Logistic Growth Model, Power Law Exponential Model, Stretched Exponential Model, Duong Model, Extended Exponential Decline Model, and Fractural Decline Curve model. This review article is dedicated to summarizing
Shale Reservoir Drainage Visualized for a Wolfcamp Well (Midland Basin, West Texas, USA)
Shale Reservoir Drainage Visualized for a Wolfcamp Well (Midland Basin, West Texas, USA) The visualization of flow near hypothetical micro-cracks normal to the main fractures in a Wolfcamp well shows such micro-cracks support the recovery of hydrocarbons from deeper in the matrix, but still leave matrix portions un-drained with the concurrent
Mechanisms and Influence of Casing Shear Deformation near the Casing Shoe, Based on MFC Surveys during Multistage Fracturing in Shale Gas Wells in Canada
Mechanisms and Influence of Casing Shear Deformation near the Casing Shoe, Based on MFC Surveys during Multistage Fracturing in Shale Gas Wells in Canada For the purpose of increasing calculation accuracy, the elastoplastic constitutive relations of materials were considered, and the solid-shell elements technique was used. The reduction of the casing’s
Great American Outpost: Dreamers, Mavericks, and the Making of an Oil Frontier
Great American Outpost: Dreamers, Mavericks, and the Making of an Oil Frontier Author Maya Rao Abstract A surreal, lyrical work of narrative nonfiction that portrays how the largest domestic oil discovery in half a century transformed a forgotten corner of the American West into a crucible of breakneck capitalism. As North Dakota became the nation's
Impact of Casing Eccentricity on Cement Sheath
Impact of Casing Eccentricity on Cement Sheath To better understand stress distribution in eccentric cement sheaths, an analytical model is proposed in this paper. By comparing the results of this model with the one’s with centric casing, the impacts of the casing eccentricity on the integrity of the cement sheath is

Cyclic CH4 Injection for Enhanced Oil Recovery in the Eagle Ford Shale Reservoirs
The confined phase behavior was incorporated in the model considering the critical property shifts and capillary pressure. Subsequently, we built a field-scale simulation model of the Eagle Ford shale reservoir. The fluid properties under different pore sizes were evaluated. Finally, a series of studies were conducted to examine the contributions of
