Shale oil stored in the shale system occurs mainly adsorbed and free states, ascertaining amount of crude is a method its content, which determines accuracy resource evaluation. Both inorganic minerals kerogen have ability to adsorb oil, but there controversy surrounding plays greatest part doing so; clarifying this would be great significance Therefore, study, evolution states were changed usi...

Hydrous pyrolysis experiments conducted on Messel shale with D2O demonstrated that a large amount of deuterium becomes incorporated into the hydrocarbons generated from the shale kerogen. In order to understand the pathway of deuterium (and protium) exchange and the role of water during hydrous pyrolysis, we conducted a series of experiments using aliphatic compounds (1,13-tetradecadiene, 1-hex...

The Pierre Shale is a marine deposit that accumulated in the Cretaceous Western Interior Seaway during the onset of Laramide tectonism in the southern Rocky Mountains region. In the eastern part of the Raton Basin near Trinidad, Colorado, ammonite biostratigraphy suggests that the base of the Pierre Shale lies within or slightly above the Lower Campanian Scaphites hippocrepis III ammonite range...

Abstract During the injection of carbon dioxide (CO 2 ) for CO capture and storage (CCS) operations, near-well (including casing, cement, rock around it) can undergo several thermal loadings. These loadings significantly increase or decrease pore pressure thus lead to mechanical failure cement sheath formation. When these failures appear in caprock, they compromise integrity site. The understan...

Figure 1 features locations of shale basins across the U.S. that bear natural gas. There are many reasons to pursue the development of natural gas. First, the supply of natural gas in the U.S. is very reliable, and the delivery system is less subject to interruption compared to imported fossil fuel. Second, the high energy content of natural gas (about 30 kJ/m3 [1000 Btu/ft3]) and a well-develo...

The effects of CO2-water-rock interactions on the mechanical properties of shale are essential for estimating the possibility of sequestrating CO2 in shale reservoirs. In this study, uniaxial compressive strength (UCS) tests together with an acoustic emission (AE) system and SEM and EDS analysis were performed to investigate the mechanical properties and microstructural changes of black shales ...

In this paper, the effect of fluidized bed temperature on primary fragmentation of Huadian oil shale was investigated experimentally in thermal state using a small-scale fluidized bed with N2 as fluidizing gas. The fluidized-bed temperatures changed from 600 °C to 1000 °C. Experimental results indicate that the fluidized bed temperature is an important factor of primary fragmentation of oil sha...

This paper analyzes and quantifies characteristic production behavior using historical data from 1084 shale gas wells in the Eagle Ford shale play from 2010 to 2014. Decline curve analysis, using Hyperbolic and Stretched Exponential models, are used to derive average decline rates and other characteristic parameters for shale gas wells. Both Hyperbolic and Stretched Exponential models fit well ...

High-volume hydraulic fracturing, a drilling simulation technique commonly referred to as "fracking," is a contested technology. In this article, we explore discourse over hydraulic fracturing and the shale industry on the social media platform Twitter during a period of heightened public contention regarding the application of the technology. We study the relative prominence of negative messag...
