Development of An Augmented Free-Water Three-Phase Rachford-Rice Algorithm for CO2/Hydrocarbons/Water Mixtures
DownloadFall 2017
In this work, we develop a robust and efficient algorithm to perform three-phase flash calculations for CO2/water/hydrocarbons mixtures on the basis of the assumption that only CO2 and water are considered in the aqueous phase. We name this new algorithm as the so-called augmented free-water...

Effect of Volume Translation on Two-Phase Equilibrium Calculations for Hydrocarbon Mixtures in a Confined Space
DownloadSpring 2020
Oil production from tight/shale reservoirs has drawn an increasing attention over the past decades. One of the essential mechanisms affecting the oil/gas production is the phase behavior of the reservoir fluids in the confined nanopores inside the tight/shale reservoirs. Many theoretical works...

Prediction of Horizontal In-situ Stress in Shale Gas Reservoirs Based on Artificial Neural Networks and Conventional Rock Mechanics ——A Case Study on Longmaxi Formation in Southern Sichuan (China)
DownloadFall 2022
Shale gas is one of the most important unconventional fossil fuel resources. It is usually developed by horizontal drilling and hydraulic fracturing techniques. The in-situ stress magnitude distribution in a given shale gas field is a significant factor that should be considered by horizontal...

Towards Accurate Density and Interfacial Tension Modeling for Carbon Dioxide/Water Mixtures
DownloadFall 2020
Phase behavior of carbon dioxide/water (CO2/H2O) binary mixtures plays an important role in various CO2-based industry processes, including CO2 injection for enhanced oil recovery and CO2 storage in saline aquifers. Engineering design of such processes requires an appropriate thermodynamic model...

Use of Nano-Metal Particles for Promoting Aquathermolysis Reaction during Cyclic Steam Stimulation
DownloadFall 2017
Cyclic steam stimulation (CSS) is one of the commonly used thermal extraction methods for heavy oil and bitumen. However, CSS is still daunted by the lower oil recovery factor compared with other thermal recovery methods, such as steam-assisted gravity drainage (SAGD). Nano-metal particles, due...
