Organic matter in the Norwood is comprised mainly of marine telalginite and solid bitumen. This member has high TOC and remaining hydrocarbon generating potential (Sh2) as well as HI and OIP...

.... Introduction The thermal maturity of organic matter in coal petrography and petroleum geology is determined by vitrinite reflectance (Diessel, 1978), which requires considerable effort and expertise (Hackley, 2015). Unlike the traditional vitrinite reflectance method, Raman spectroscopy offers nondestructive...

... and 2 samples from Well Ccentral that span 24 feet. Data sets such as logs, X-ray diffraction, Leco TOC, multi-scale imaging, and pore scale quantitative analyses were integrated to analyze porosity associated with organic matter, pore size and pore shape distributions. The key findings comparing...

...-class source rock with an average total organic content (TOC) of 11.5 wt.% (LeFever et al., 1991; Sonnenberg and Pramudito, 2009; Jin, 2014, Lilis 2013). The high TOC of the UBS is attributed to the enhanced preservation potential of organic matter (OM) due to reducing conditions during its deposition...

... Abstract Kerogen, which is the main constituent of organic matter and plays an important role in hydrocarbon adsorption behavior in shale. In this paper, molecular dynamic (MD) simulation was performed to characterize the adsorption behavior of hydrocarbons in kerogen pores. This study showed...

Produced gases in the dry gas region are mixtures of CH4 cracked from over-mature refractory kerogen and hydrocarbons generated by extensive (> 70%) oil/wet gas cracking...

... is prohibited. ABSTRACT Total Organic Carbon (TOC) content represents the weight percent of organic matter present in source rocks. The TOC content is a key petrophysical parameter for evaluating the quality of a reservoir that can be measured from core samples in the laboratory. However, these core samples...

...-SEM microscopy is used to reconstruct a 3D volume where organic matter, pores and minerals can be identified and segmented. Thin sections are then micro-machined by FIB-SEM, mounted on a TEM grid and thinned down to electron transparency (about 100 nm). High-magnification micrographs highlighting...

... Abstract Shale reservoir is a complex and highly heterogeneous system. There are a large number of pore-throat structures and variable permeability at the micro-scale. In addition, because both inorganic matrix and organic matter exist in shale reservoir, the slip effect and multi-layer...

NMR provides guidance in determining the organic matter hosted porosity and the bulk volume fluids held within the defined porosity, as these contribute towards the negative reservoir quality indices. Therefore, there has been extensive research using low field NMR laboratory and field...

... Abstract Almost simultaneously, advances were made in understanding both the processes within the source rock organic matter that accompany the generation and expulsion of hydrocarbons and in the acquisition, processing, and quantitative interpretation of 3D seismic data. In particular...
