... Abstract Reliable thermal data control and appropriate interpretation of basin evolution history are the most important aspects in petroleum system analysis and basin modeling for the source rocks' maturity, but they are often challenging to obtain completely and be applied properly. Many...

... routinely by numerous companies to predict the mechanical properties, density, and associated TOC of many formations, there is yet to be a direct link made between TOC loss, kerogen conversion, and the associated changes in rock properties. This work documents the importance of TOC loss during maturation...

... 1.0 Abstract This study investigates the validity of geochemical paleoredox proxies in mature organic-rich shales. Classically, Fe-S-C org ternary diagrams and C-S crossplots have been used to differentiate between oxic, dysoxic, and anoxic / euxinic conditions, but should be limited...

... Abstract The evolution of pores and fluids due to thermal effects is a key factor for predicting shale gas production. However, different fluid types and a wide range of pore sizes pose difficulties for characterization. We experimentally changed the fluid distribution and maturity of shales...

... of the Lancones Basin; and the geochemical interpretation of the data from outcrops and the well Abejas 1X, with which the geochemical properties of organic matter, thermal maturation and hydrocarbon abundance were evaluated, in order to determine the hydrocarbon potential of the source rock; and during all...

... Summary Low temperature (60 and 100 °C) and long-term (6 months to 5 years) heating of pre-evacuated and sterilized shales and coals containing kerogen Types I (Mahogany Shale), II (Mowry Shale and New Albany Shale), and III (Springfield Coal and Wilcox Lignite) with low initial maturities...

... Abstract The sequential relationship between the Jurassic Tuwaiq Mountain source-rock maturity, petroleum generation, over-pressuring, and expulsion-fracturing was evaluated over the Arabian Intrashelf Basin. The evaluation is part of the ongoing assessment of the Jurassic unconventional...

... Abstract Facing declining production, the U.S. started looking for new unconventional resources. Shale gas and oil are considered to be the future of the U.S. energy industry. One of the biggest factors governing the success of shale development is maturity. Thermal maturity not only reflects...

... Summary There is general agreement across industry regarding the importance of thermal maturity as one of the key parameters defining core areas in unconventional plays. In such plays, the process of organic maturation has implications for both source and reservoir potential. From a source rock...

...) and X-ray fluorescence (XRF) spectroscopic analysis of 64 Neal shale samples indicate the formation is clay-rich and quartz-poor, with the clay content averaging 47.2 wt% and the quartz content averaging 25.2 wt%. Nine samples of the Neal shale, representing 3 different levels of thermal maturity, were...

... Summary Thermal maturation is often a key element in resource-play exploration, frequently relying on TMAX from pyrolysis experiments. This value is only a proxy for Transformation Ratio (TR) which measures fractional conversion of kerogen to hydrocarbons. Further, TMAX says nothing about...

... assays, Rock Eval, infrared spectroscopy, nuclear magnetic resonance relaxation analysis, density, surface area and pore volume measurements, and scanning electron microscopy. Particular attention is paid to the organic matter: kerogen, bitumen, and coke. We find that oil shale artificially matured...

..., based on optical methods to analyse both sides of the system: the source rock potential by high resolution studies of kerogen composition and maturation and the reservoir potential by the analysis of kerogen microporosity estimated from kerogen preservation, indicating the gas storage capacity...

... Summary Artificial maturation methods are used to induce changes in source rock thermal maturity without the uncertainties that arise when comparing natural samples from a particular basin that often represent different levels of maturation and different lithofacies. A novel uniaxial...

... result from mixed effects of the original depositional environment and progressive maturation. Based on the modified van-Krevelen diagram, the kerogen type present in Bakken shale is primarily Type II marine oil-prone kerogen, but along the shallow east flank of the basin there is Type III kerogen input...

..., level of organic maturity, and kerogen type. At high TOC and low maturity levels, source rocks have very small effective porosity and sub-economical permeability. Hydrocarbon production from these resources requires in situ retort techniques. At high maturity level (gas condensate and dry gas window...
