Role of sulphates and chloride ions in improved oil recovery in a hybrid smart-low salinity flooding technique
… utilisation of existing hydrocarbon resources. Oil and gas are deemed the most conventional and common sources of energy, formed as a result of degradation of fossils deeply buried in underground. Utilising oil and gas require their extraction from their “traps” termed reservoirs. Their …

EOS modeling and reservoir simulation study of Bakken gas injection improved oil recovery in the Elm Coulee field, Montana
… Even with this new technology, the primary recovery factor is believed to be only around 10%. This study is to evaluate various gas injection EOR methods to try to improve on that low recovery factor of 10%. In this study, the Elm Coulee Oil Field in the Williston Basin was selected as the …

Utilization of Carbonated Water Injection (CWI) as a Means of Improved Oil Recovery in Light Oil Systems: Pore-Scale Mechanisms and Recovery Evaluation
… solubility value is observed for both water and oil phases when the pressure increases in the range of P = 0.7–10.3 MPa. Furthermore, it was found that the solubility of CO2 reduces with increased temperature. In addition, the results obtained from swelling/extraction tests revealed that the oil …

Surfactant-free Aluminum Silicate-based Nanofluids for Enhanced Oil Recovery from Austin Chalk Carbonate Reservoirs
… the application of nanoparticles for enhancing oil recovery in carbonate reservoirs has received great attention from various researchers across the oil and gas industry. In contrast to sandstone reservoirs, carbonates are naturally neutral-wet or preferentially oil-wet. Understanding the …

A Numerical Approach for Oil Slug Mobilization in a Capillary Tube Under Absence and Presence of External Excitations
… attempts to study the mobilization of an oil drop, also known as a \slug", via the aid of a water film. This differs from other work in this area wherein the oil drop is forced through the throat of a pore using external excitations. In the first simulation, an oil drop is placed in a …

Investigating and modeling tar-mats in a Kuwaiti carbonate reservoir and their role in understanding oil reserves and recovery economics
… tar-mats have been thought to impede primary oil extraction, thus necessitating further improved oil recovery (IOR) technology applications. However, this research considers tar-mats as potential sources for unlocking extremely difficult crude oil, less than 5 ⁰API. The main objective of the …

Novel insights into low salinity water flooding enhanced oil recovery in sandstone reservoirs
… global energy demand and the natural decline in oil production from mature oil fields have been the main incentives to search for methods to increase recovery efficiency for several decades. Water flooding is extensively applied worldwide to improve oil recovery. The recent drop in oil prices has …

Optimization of chemical enhanced oil recovery methods for naturally fractured carbonate reservoirs
Carbonate oil reservoirs are important energy sources, accounting for over 60% of the world’s oil reserves. Recovering oil from these reservoirs is challenging, especially if they are naturally fractured. Waterflooding is inefficient because water flows through the highly permeable fractures and …

Measurement and modeling of fluid-fluid miscibility in multicomponent hydrocarbon systems
… become a major gas injection process for improved oil recovery. Laboratory evaluations of gas-oil miscibility conditions play an important role in process design and economic success of field miscible gas injection projects. Hence, this study involves the measurement and modeling of …

Chemical treatment and gas huff-n-puff for enhanced oil recovery in oil shale reservoirs
Shale oil contributes more than 60% to the US oil production. Shale oil production has been feasible because of technological development for horizontal wells with multistage hydraulic fracturing. However, after primary production, more than 90% of the oil is left behind in shale oil reservoirs due …

Mechanistic Modeling, Design, and Optimization of Low Salinity Waterflooding
… (LSW) is an emerging attractive enhanced oil recovery (EOR) method because of its oil recovery performance and relatively simple, environmentally friendly implementation, when compared with conventional high salinity waterflooding and EOR approaches. Most studies on the subject have …
