... Abstract Kerogen as one the main constituents of mud rocks is not thoroughly understood in terms of its mechanical characteristics. Kerogen is not as stiff as inorganic minerals within the rock matrix, but it can have a significant impact on the propagation of fractures. This becomes more...

... point of oils in liquid rich shale play because of the effect of confinement of oils in nano pores has caught attention of the researchers. Our prior research based on modeling and experiments show that kerogen interacts with the oil that leads to changes in bubble point of oils. There has not been any...

... Abstract In liquid rich shale plays, the hydrocarbons may remain associated with the parent kerogen. During catagenesis of kerogen in the geologic history, the kerogen is converted to hydrocarbons. A fraction of the generated hydrocarbons is expelled from the residual kerogen matrix, while...

... Abstract Shale gas reservoirs are fine-grained, organic-rich rocks with a well-developed pore network structure within the organic matter (kerogen). Organic pores in shale reservoirs exhibit small radii in the range of 0.5 to 100 nanometers, which indicate that non-Darcy flow mechanisms...

..., efficient enhanced oil recovery methods are highly desired to improve shale oil recovery. As an essential component of shale, kerogen plays a key role in generation, adsorption, storage and migration of hydrocarbons in shale as well as the geomechanical properties of shale. On the other hand, during...

... mechanism provided by dissolved gas in kerogen. All these storage mechanisms must be considered for estimation of original gas in place (OGIP). Otherwise pessimistic values of OGIP and recoveries will be obtained by ignoring any of these mechanisms. This paper presents a new easy-to-use Material Balance...

Kerogen, macro-fractures, micro-fractures, and an inorganic matrix are represented directly in the four-porosity system. hydraulic...

... Thus, improved kerogen models better than the conventional graphene slit pore systems, which incorporate structural features that represent the kerogen pore systems observed in SEM images, including mixed wettability, surface roughness, tortuous paths, and material disorder, are proposed...

... Porosity cannot be routinely estimated from conventional well logs due to complex lithological components and existence of kerogen. Even with introduction of correction factors, sonic, density and neutron logs are not generally accepted for porosity evaluations. Quite a few studies have been done...

.... In heavy oils, the oil relaxation can be enhanced by a wettability change to an oil/mixed-wet system. Another case of hydrocarbon-wet systems is hydrophobic kerogen. Consequently, the oil diffusion line as a function of viscosity ( T 2 ) must also be modified before the 2D map interpretation. This can...

The bulk of the oil storage in source rocks however is in kerogen, where dominantly diffusive rather than Darcy...

... and nano-indentation have been employed to calculate mechanical properties of kerogen at the submicron level in Woodford shale samples of different maturities. A displacement of 500 nm was applied to investigate mechanical properties of kerogen and force in the range of 400–500 mN was applied to measure...

... and its integration with an HTGR. Development and deployment of a commercial HTGR may also require 10 to 15 years. Thus, this conceptual study of integrating an HTGR with an in situ oil operation is timely. Shale oil is produced from oil shale by pyrolyzing the kerogen molecules within the oil shale...

The amount of generated hydrocarbon at this stage (S2 (mg HC/g TOC)) is called the potential generative hydrocarbon of the source rock. At the final stage of retort, CO2 will be released which forms S3. S3...

... Abstract Heterogeneity of properties along horizontal shale gas wells has a significant impact on the quality of completion as well as on production from each stage. This heterogeneity can exist in the quality of the reservoir, such as changes in kerogen content and maturity, free porosity...

Assigning gray scale ranges to features, volumes can be constructed which show three dimensional distributions of these features. Some shale samples show significant kerogen content...

This paper uses SEM imaging of Haynesville, Horn River, Barnett and Marcellus Shales to illustrate that pore types other than those hosted by organics are present in unconventional shale gas reservoirs, and that they are continuous and connected to kerogen-hosted pores. In addition, we present...
