Effect of thermal maturity on nanomechanical properties and porosity in organic rich shales (a Bakken shale case study)
… spots detection. In self-sourcing mudrocks, maturity (extent of oil generation), porosity and abundance of natural fractures are the main parameters to make them economical. Understanding the elastic properties of self-sourcing formations and their correlation with maturity can provide …

Application of Raman Spectroscopy and Transmission Spectroscopy for Shale Reservoir Characterization: Thermal Maturity Correlation and Organic Matter Type Differentiation
… as evaluated using geochemical techniques, and thermal maturity. The standard measures of thermal maturity include vitrinite reflectance and various other visual (e.g., TAI, solid bitumen reflectance, etc.) and geochemical measurements (e.g., Rock-Eval T-Max) all reported as %Ro or an equivalent …

Gravity Modeling, Seismic Stratigraphy, and Thermal Maturity Modeling of Hydrocarbons of the Permian Foreland Basin, USA, and the Sergipe-Alagoas Rifted-Passive Margin, Brazil
… of deep basinal areas that may host productive, thermally mature source rock kitchens controlled in part by strike-slip faults aligned with AGM edges. In Chapter 3, I created a 3D full tensor gradiometry (FTG) gravity model for the northeastern Delaware Basin. Tzz inversion results provide …

Geochemical controls on production in the Barnett Shale, Fort Worth Basin.
… quantity and character of organic matter, the thermal maturity history, and the mineralogy of the Barnett Shale. This study uses Rock Eval to investigate the quantity and character of the organic matter and general thermal maturity, vitrinite reflectance, δ¹³C of produced methane and methane …

A study of the effects of organic matter on illitization in the Woodford Shale, Oklahoma and Kansas
… The Woodford is productive over a wide range of thermal maturity (based upon vitrinite reflectance), yet most clay mineral studies report primarily illite (Caldwell, 2011 & Whittington, 2009). A previous report contrasts this behavior to other late Paleozoic shales in Oklahoma (Kowal, 2016). The …

Integrated Experimental Characterization of the Lower Huron Shale in the Central Appalachian Basin
… Additionally, four shale samples with varying thermal maturity were characterized by the complementary Raman and FTIR spectroscopy, and curve-fitting results successfully demonstrated the change of chemical structures with the evolution of thermal maturity. Raman spectroscopy results show that …

Scientific Underpinning of Concepts of Geochemical Inversion: Developing and Improving Methods with Application to Petroleum System Analysis
… is a process for inferring source facies and thermal maturity of a petroleum from its molecular and isotopic characteristics. Comprehensive analysis for diverse molecular markers, including saturated and aromatic biomarkers, organosulfur compounds, and diamondoids in petroleum, are important …

Identification of a thermal maturation high, revised maturity map, and production trends of the Late Devonian Duvernay Formation, Alberta, Canada.
… 250 million barrels of oil equivalent. Regional thermal maturity trends across central and southern Alberta published in the literature are poorly understood and inconsistent with produced fluid types. The focus of this dissertation is to refine thermal maturity trends of the Duvernay Formation. …

Offshore El Salvador: the first interpretation of a unique 2-D seismic dataset and implications for a working petroleum system in a forearc basin setting
… pertains to deposition of suitable source rocks, maturity, timing, and migration of hydrocarbons. The Corvina-2 well offshore Nicaragua, and the Esso Petrel-1 and Madre Vieja-1 offshore Guatemala aid in constraining lithological data in the region. Maturity data from regional studies indicate that …

Assessment of the petroleum generation potential of the Neal Shale in the Black Warrior Basin, Alabama
… Neal shale, representing 3 different levels of thermal maturity, were analyzed by FIB-FESEM to determine if organic porosity increases with thermal maturation. Based on this analysis, Neal shale porosity is a mixture of fissure, organophillic, and interparticle porosity. However, no increase in …

HYDROCARBON ACCUMULATION OF SHAHEJIE FORMATION, BOHAI BAY BASIN, CHINA
… based on reconstructions of the burial, thermal, maturity, structural, and migration histories. The present-day and paleo heat flows of the studies basin in 1D models were calibrated with measured borehole temperature and vitrinite-reflectance data. Results indicate that the present-day …

Thermal History of the Chesapeake Bay Impact Crater
… to characterize a possible post-impact hydrothermal system. Thermal maturity and radiogenic techniques were used to estimate the temperature history of the crater sediments. Core samples from one borehole just outside the crater, two within the annular trough, and one shallow borehole within …
-
Kerogen variation in a Devonian half graben system
… analyses from across Orkney indicate that the thermal maturity of the sediments is within the thermal range of hydrocarbon generation. Additionally the uniform spread of maturity values across Orkney indicates that fault movement was never great enough to cause differential thermal maturity …

Integrated approach to solving reservoir problems and evaluations using sequence stratigraphy, geological structures and diagenesis in Orange Basin, South Africa
… in order to determine the provenance, type and thermal maturity of organic matter present in sediments of the Orange Basin. The results revealed a complex diagenetic history of sandstones in this basin, which includes compaction, cementation/micritization, dissolution, silicification/overgrowth …

Fracture-enhanced porosity and permeability trends in the Bakken Formation, Williston Basin, western North Dakota
… porosity and permeability, high organic content, thermal maturity, and relative lateral homogeneity. Core analysis has shown the effective porosity and permeability development within the Bakken Formation to be primarily related to fracturing. </p><p> In theory, lineaments mapped on the surface …

Thermal history model of the Williston Basin
… by empirical and analytical methods. A review of thermal-mechanical models suggests that the Williston Basin was formed by more than one mechanism. The Williston Basin may have been initiated by a thermal event followed by thermo-flexural or phase transition subsidence. </p><p> The heat that …

SOURCE AND MATURATION OF HYDROCARBONS IN THE FRIO FORMATION OF THE HUMBLE FIELD, SOUTHEAST-TEXAS GULF COAST BASIN
The source and maturity of hydrocarbons in the Frio Formation of the Humble oil field, Harris County, Texas, from the East Texas Gulf Coast basin, were interpreted by combining the geochemical characteristics of the Humble oils and thermal evolution history of the Humble field. Ten oil samples from …
