Modeling CO2 Sequestration and Enhanced Gas Recovery in Complex Unconventional Reservoirs
… is proposed as a way to mitigate the greenhouse gas effect and potentially contribute to economic prosperity through enhanced methane recovery. In 2009, the Virginia Center for Coal and Energy Research (VCCER) injected 907 tonnes of CO2 into one vertical coalbed methane well for one month in …

Role of connate water salinity in gas dispersion during enhanced gas recovery by carbon dioxide injection and sequestration
… influence mixing between CO2 and CH4 in naturalgas reservoirs can provide an avenue to minimise the gas dispersion during Enhanced GasRecovery (EGR). This highlights EGR’s field scale adoption as a potential method forsimultaneously reducing CO2 emissions through sequestration and enhancing …

Enhanced gas recovery and storage: the role of N2 during natural gas displacement by CO2 flooding in sandstone rocks
… dioxide (CO2) injection and storage method for enhanced gas recovery holds enormous promise for concurrent natural gas recovery and CO2 storage from depleted gas resources. However, its potential application as part of climate friendly pilot scale research among industry and researchers is …

Monitoring for Enhanced Gas and Liquids Recovery from a CO2 'Huff-and-Puff' Injection Test in a Horizontal Chattanooga Shale Well
Permanently sequestering carbon dioxide (CO2) in gas-bearing shale formations is beneficial in that it can mitigate greenhouse gas emissions as well as enhance gas recovery in production wells. This is possible due to the sorption properties of the organic material within shales and their greater …

Methane adsorption into sandstones and its role in gas recovery from depleted reservoirs
Depleted gas reservoirs represent the most viable option for research and development and are the most preferred method for Enhanced gas recovery and sequestration application. The adsorption process acts as a displacement mechanism in the enhanced gas recovery, therefore investigating this process …

Integrative Geophysical and Environmental Monitoring of a CO2 Sequestration and Enhanced Coalbed Methane Recovery Test in Central Appalachia
A storage and enhanced coalbed methane (CO2-ECBM) test will store up to 20,000 tons of carbon dioxide in a stacked coal reservoir in southwest Virginia. The test involves two phases of CO2 injection operations. Phase I was conducted from July 2, 2015 to April 15, 2016, and injected a total of 10, …

Numerical Simulation and Optimization of Carbon Dioxide Utilization for Enhanced Oil Recovery from Depleted Reservoirs
… interest in CO<sub>2 </sub>utilization is the Enhanced Oil Recovery (EOR) from depleted reservoirs. In an Enhanced Oil Recovery system, a depleted or depleting oil reservoir is re-energized by injecting high-pressure CO<sub>2</sub> to increase the recovery factor of the oil from the reservoir. …

Modeling of Methane and Carbon Dioxide Sorption Capacity in Tight Reservoirs Using Machine Learning (ML) Techniques
… combinations of potential features, e.g., gas (CH4 and CO2), rock type (either shale or coal family), TOC (total organic carbon), moisture, temperature, porosity, geological properties, etc., resulting in high accuracy (96 to 98%) for 69 sets of “unseen” experimental data with 1384 data …
