Present study demonstrates a two-stage integrated process for production of hydrocarbon oil designated as ALGLIQOL, with potential to be utilized as liquid transportation fuel. Stage-I involves in-situ catalytic hydrothermal liquefaction (HTL) of…
The compatibility of an amine-based foaming agent, Duomeen CTM [C12-14N(CH3)C3N(CH3)2], and crude oil on supercritical CO2 foam transport are evaluated for a carbonate reservoir with high pressure and high temperatures (HPHT) and ultrahigh…
Carbon dioxide storage in geological formations is one of the mature strategies developed for controlling global warming. This paper represents a comprehensive experimental and geochemical modeling study to analyze CO2-brine-rock interactions in a…
In the process of CO2 geological sequestration, there is a risk that CO2 will leak into groundwater, resulting in a series of physical and chemical reactions, with influence on chemical compositions of groundwater. In this work, numerical simulation…
Understanding CO2-induced micro-structural changes at the imperfections in wellbore cement is vital for assessing the risk of CO2 leakage through wellbore cement under geologic CO2 storage (GCS) conditions. To investigate the evolution of a flow…
Geologic carbon storage projects aim to permanently trap large volumes of CO2 in reservoir rock sealed with low permeability layers. As high-pressure supercritical or liquid CO2 is injected, hydromechanical and chemical processes caused by the…
During geological CO2 storage traditionally CO2 is injected subsurface into a high permeability reservoir capped by a low permeability seal to trap the buoyant supercritical plume. Wastewater from oil and gas production is also currently disposed of…
During the analysis of the 47 values of CO2 derived from carbonates, the acid fractionation factor not only allows 47 values produced from carbonates and reacted at different temperatures (usually 25 and 90 C) to be compared to one another, but also…
Geological H2 storage plays a central role to enable the successful transition to the renewable H2 economy and achieve net-zero emission in the atmosphere. Depleted oil and gas reservoirs are already explored with extensive reservoir and operational…
Close examination of surface interactions between calcite and crude oil is relevant to better understand the mechanisms that lead to wettability changes in petroleum reservoirs. Mineral surface wettability is a determinant factor in petroleum…
Asphaltenes are being a proxy of kerogen in the reservoir oil, which they have structural similarity. This characteristic provides an invaluable tool for obtaining oil fingerprints from the structural composition of asphaltenes. Since these compounds…
Igneous rocks in deep basins are important unconventional petroleum reservoirs. Storage space and porethroat structure of igneous rocks are crucial to be considered as effective reservoirs. There developed large-scale petroleum reservoirs in the…
Shale samples of lacustrine Shahejie Formation from the Well F39X1 drilled in Qikou sag were used to study microstructures, mineralogy, and organic geochemistry and their impacts on oil storage response. Samples are quartz and clay rich and contain a…
To investigate the mechanism of local porosity modification in a carbonate reservoir caused by the acidic components associated with natural gas generation, a numerical model for the charging of natural gas rich in acidic components (CO2) was…
The present work describes a set of four in-situ combustion (ISC) tests for assessing the applicability of the technology for the heavy oil (19 API) carbonate field and determining the optimal initial oil saturation. The potential candidate for the…
The origin and potential source of the presalt natural gas in the Lower Paleozoic Ordovician carbonates within the Ordos Basin, China, is heavily debated, and the causes of carbon isotope reversal are currently unclear. This study analyzes the source…
Concrete, a mixture composed of a cementation agent, mineral aggregates, and water has the potential to serve as a gigaton-scale sink for carbon dioxide (CO2). This could make concrete the worlds largest CO2 utilization opportunity. CarbonBuilts…
It is crucial to determine the sequence of reservoir tightening and hydrocarbon accumulation for analyzing the accumulation dynamics, oil migration mode, and oil distribution pattern of tight oil reservoirs. The tight sandstone reservoirs in the Fuyu…
Leakage of oil and gas is associated with significant calcite cementation in the overburden of the Frigg Gamma Field. This cementation makes seismic imaging of the field with conventional streamer seismic extremely challenging. Different approaches…
Micro-pits could propagate during in-service life in facilities such as crude oil storage tanks in which calcium salts are present. Calcium is known to influence pit initiation and propagation but explanation on pitting kinetics on low carbon steel…
