Summary: Research indicates that the influx of gas condensates into the upper part of the preexisting oil reservoir, possibly facilitated by a major fault, caused thermodynamic disequilibrium, leading to de-asphalting and subsequent deposition of solid bitumen. The initiation of bitumen deposition was estimated to be 129 million years ago, potentially improving sealing efficiency along the unconformity and affecting trapping of subsequent hydrocarbon charges in the underlying reservoir.

Summary: This study focuses on the diagenetic evolution of the reservoir in the E(3)w(3) member of the Oligocene Weizhou Formation in Beibuwan Basin, northern South China Sea. The occurrence states and effects of different clay minerals, including chlorite, illite, kaolinite, and quartz cement, are analyzed. The study identifies three different occurrences of chlorite and three major types of diagenetic kaolinite. The presence of chlorite coating has a significant effect on quartz overgrowth.

Summary: The study of solid bitumen at the Pliensbachian-Toarcian boundary in the Bizanet section revealed four families, with family D considered as indigenous bitumen and the other three families as migrated. The absence of solid bitumen in the Pont de Suert section suggests the importance of the morphotectonic context in the migration of hydrocarbons within the Pyrenean Basin.

Summary: The correlation of hydrocarbon source in highly-mature and over-mature stages is challenging in natural gas exploration. This study investigates the inorganic geochemical information of reservoir bitumen and potential source rocks to explore the source of highly-mature natural gas in the central Sichuan Basin. Different depositional environments and characteristic parameters of the source rocks are used as the basis for gas-source correlation. The results reveal the differences in gas source between different formations, providing new insights for the study of gas accumulation in the central Sichuan Basin.

Summary: This study investigates the source and formation timing of solid bitumen in the Sinian Dengying Formation dolomite in the northern Sichuan Basin using biomarkers and Re-Os geochronology. The results show that the high thermal maturity solid bitumen originated from marine shale and was formed by the thermal cracking of crude oil. Initial oil generation began in the Late Cambrian to the Early Silurian, leading to a giant paleo-oil accumulation during the Late Triassic, with thermal cracking occurring from the Late Triassic to the Early Cretaceous. The Re-Os isotopes yielded ages that represent the final timing of dry gas generation.

Summary: The Middle Jurassic syn-rift sediments in the Western Desert of Egypt, known as the Khatatba Formation, have potential as hydrocarbon reservoir targets. This study integrates seismic, well logs, and core data to analyze the sedimentary patterns and factors affecting distribution and quality of reservoir facies. The formation comprises two discrete units with distinct rift phases, showing repeated cycles of progradation and retrogradation with an overall progradational trend.

Summary: This study investigates the formation process and Re-Os systematics of bitumen in a CO2-rich pre-salt gas reservoir in the south Kwanza Basin, offshore Angola. The research suggests that the formation of bitumen is related to the concentration and temperature gradients created by the downward expansion of magmatism-derived CO2 within the reservoir, and the bitumen has a similar age as the CO2 charging. Additionally, the Os isotope composition indicates that the lacustrine Red and Grey Cuvo formations could be the source rock for the bitumen in the studied reservoir.

Summary: The charge characteristics of kaolinite samples coated with bitumen, asphaltene, or maltene were studied using electrodeposition. It was found that bitumen-coated and maltene-coated kaolinite deposited on the anode, while asphaltene-coated kaolinite deposited on both anode and cathode. The carboxyl groups in the organic coating layer were the main factor contributing to the negative charges of the coated kaolinite, with higher concentrations in bitumen and maltene coatings compared to asphaltene coating. XPS analyses confirmed the higher nitrogen content in the cathode-deposited organic-coated kaolinite films and the presence of carbon and sulfur species with higher oxidation states associated with oxygen in the anode-deposited films.

Summary: This study investigates a process for partial upgrading of Canadian oil sands bitumen through modeling and simulation, including solvent deasphalting, thermal cracking, and hydrotreating. The study found challenges in achieving product quality targets without diluent addition under two operating scenarios, with the formation of new asphaltenes during thermal cracking identified as a key factor impacting product yield and quality.

Summary: Shale gas, primarily methane, is currently being developed to meet global energy demands. Using Density Functional Theory (DFT) and Molecular Dynamics (MD) techniques, researchers studied methane transport in shale pores and found that methane predominantly undergoes physisorption on the interface, with stronger adsorption on the kaolinite region.

Summary: This study aims to understand the effects of different types and wettability of clays on bitumen extraction from mined oil sands. The results showed that hydrophilic clays had a detrimental effect on the extraction process, with montmorillonite being the worst. The crucial role of clays in slime-coating on bitumen was studied, and clay concentration was found to determine the hetero-coagulation process between bitumen and clay.

Summary: This study conducted a comprehensive geochemical analysis of solid bitumen samples discovered in the Cambrian reservoirs of the Ordos Basin. The results showed that the solid bitumen had intergranular pores and micro-fractures with dolomite and limestone surfaces. The samples also exhibited significant thermal evolution and were mainly composed of pyrobitumen, confirming the hypothesis. The study also found that the Lower Cambrian source rocks played a significant role in the formation of Cambrian natural gas and solid bitumen in the Southern Basin of the Ordos Basin.

Summary: The reservoir characteristics and hydraulic flow unit properties of the Khatatba Formation in Qasr field, Western Desert, Egypt were investigated using various methods to analyze and characterize the sandstone. Samples from three different wells showed that the sandstone can be classified into three rock types, where Rock type I has the best storage capacity and permeability, while Rock type III is the poorest quality reservoir.

Summary: The characteristics of the source rocks in the early to late Miocene Belait Formation of Brunei Darussalam were evaluated utilizing Rock-Eval, biomarker analyses, and organic petrography. The results showed that coal and some carbonaceous samples from the formation have good generating potential, while non-coal samples generally have lower potential. The facies analysis suggested a mangrove setting in a lower delta plain for the deposition of coals, with mostly herbaceous and arboreal plants growing, under predominantly oxic and brackish conditions.

Summary: The study investigated the petroleum generation kinetics of the Early to Late Miocene Belait Formation in Brunei-Muara district using the PhaseKinetic approach. The source rock characteristics indicate mainly type III-II and type III kerogens, with petroleum grading from paraffinic-naphthenic-aromatic high wax to gas and condensate. Pyrolysis data suggest that hydrocarbon generation occurs at temperatures ranging from 105-120 degrees C for 10% transformation ratio, with the end of generation expected at temperatures above 170 degrees C.
