Analysis of petroleum source rocks of the Bakken Formation (Devonian and Mississippian) in North Dakota
… used to evaluate the Bakken shales as petroleum source rocks include organic carbon measurements, chromatographic analysis of organic extracts, pyrolysis, vitrinite reflectance, and visual kerogen typing. Organic carbon measurements revealed the Bakken shales to be very organic-rich (average of …

Creep properties of source rocks using indentation : the role of organic matter on texture and creep rates
Gas shale formations are source rocks of variable mineralogy with oil and natural gas production potential. Due to their low permeability, these source rocks can be produced only after fracturing. Therefore, understanding and characterizing the time-dependent mechanical properties of these …

Identifying source rocks and reservoir elements of South China Sea grabens using 3D seismic data, West Natuna Basin, Indonesia
Reservoir quality and source potential are significant risk factors when exploring for hydrocarbons in Southeast Asian rift basins (Sladen, 1997b). In the West Natuna Basin, Indonesia, wells infrequently penetrate most of the synrift section, and as a result source and reservoir potential of the …

Hydrocarbon occurrences within the La Popa Basin: Potential source rocks, thermal maturation, and hydrocarbon migration along the La Popa salt weld, La Popa Basin, Ne Mexico
… collected along the weld suggest a clay-rich source rock for the hydrocarbons. None of the potential source rocks sampled yielded results indicative of a good source rock, but the Parras Shale and Potrerillos Formation are most similar to the migrated material based on biomarker analysis. …

Natural Gas Generation Potential of the Wufeng-Longmaxi and Niutitang Shale Formations, Sichuan Basin, China: Insight from Hydrous and Anhydrous Pyrolysis
… investigated the gas generation potential of the source rocks using artificial thermal maturation, e.g., pyrolysis, to investigate hydrocarbon generation potential. In this study, hydrous and anhydrous pyrolysis experiments were conducted on black shale core and outcrop samples to evaluate and …

Geological and Geochemical Investigation of the Petroleum Systems of the Permian Basin of West Texas and Southeast New Mexico
Fifty (50) crude oils and nineteen (19) source rock samples from strata ranging in age from Ordovician to Middle Permian, and distributed widely over the Permian Basin, were studied geochemically and chemometrically to identify the petroleum systems within the greater Permian Basin. Variations in …

A seismic stratigraphic analysis and petroleum system characterization of the cretaceous sequence in central Walvis basin, offshore Namibia
… the occurrence and preservation of mature source rocks and good reservoir lithofacies in the northern and central parts of the Walvis Basin remains exploration risks. This study aims to address this gap by carrying out a seismic stratigraphic analysis of 2D seismic data and well data in the …

Structural diagenesis of bed-parallel and bed-normal fractures, Cretaceous Crato Formation carbonate rocks, NE Brazil
… be present in well-layered regions of pre-salt source rocks assuming petroleum generation is significantly high or fluid overpressure occurred sufficiently early in the burial history of pre-salt source rocks. Bed-parallel fractures may serve as storage sites or assist in the lateral transport …

Basin analysis of Tertiary strata in the Pattani Basin Gulf of Thailand
… the lithosphere may have extended the basement rocks as much as 45 to 90 km and have caused the upwelling of aesthenosphere resulting in high heat flow. The sedimentary succession in the Pattani Basin is divisible into synrift and post-rift sequences. The synrift sequence comprises three …
