Wave Velocities in Shales – A Rock Physics Model
65th EAGE Conference & Exhibition, 2003C-13 WAVE VELOCITIES IN SHALES – A ROCK PHYSICS MODEL Abstract 1 A rock physics model for predicting wave velocities in shale has been established based on the Hashin-Shtrikman (1963) theory for elastic properties of composite media. The model has been used to analyse P-wave velocity measurements on 20 different shale cores with porosities ranging from

Physicochemical analysis of a kerogen rock (oil shale)
Moscow University Chemistry Bulletin, 2016A composition of a kerogen was studied with the use of chemical, physical, and spectral (IR, NMR, XRD, XPS, and ESR) methods. A yield and main characteristics of kerogen were found.

Rock characterization of Fayetteville shale gas plays
Fuel, 2013Abstract Multiple techniques were used to characterize the petrophysical properties of the rock samples from the Fayetteville shale gas play, including clay mineralogy, wettability, organic matter and their maturation, submicron pore structure, and 3-D pore structure. X-ray diffraction (XRD) mineralogy analysis showed high quartz and low clay content

Investigation of Oil Adhesion to Shale Rocks for EOR
SPE International Conference on Oilfield Chemistry, 2017Abstract Significant work is ongoing within the industry to determine a best practice for maximizing oil recovery from fractured oil-wet shale reservoirs. Rapid decline curves are often observed and water flooding can be largely ineffective because of negative capillary pressure.

Comparison of Carbonate and Shale Source Rocks
1984As with shales, the source potential of carbonate rocks depends primarily upon the organic facies rather than the mineral matrix. Where the depositional and early diagenetic environment is highly oxygenated, the total-organic-carbon (TOC) content is low. The remaining kerogen is highly oxygenated, with a negligible generative capacity for hydrocarbons,

TECHNICAL CHARACTERISTICS OF SOME SHALE ROCK
2017Manufactured and tested in laboratory samples of the series to determine the technical characteristics of the shale rocks. The data on the physical and mechanical strength, thermal, elastic, layered, anisotropic, hydraulic and wave properties of ...

Compaction of Sedimentary Rocks: Shales, Sandstones and Carbonates
2015The physical properties of sedimentary rocks change continuously during burial as a response to increasing stress and temperature; they also change to a certain extent during uplift and cooling. There is an overall drive towards lower porosity with depth, which increases the sediment density and sonic/seismic velocity.
