Characteristic forced and spontaneous imbibition behavior in strongly water-wet sandstones based on experiments and simulation
(Peer reviewed; Journal article, 2022-05)Forced and spontaneous imbibition of water is performed to displace oil from strongly water-wet Gray Berea (~130 mD) and Bentheimer (~1900 mD) sandstone core plugs. Two nonpolar oils (n-heptane and Marcol-82) were used as ... -
A Critical Review on the Use of Shallow Geothermal Energy Systems for Heating and Cooling Purposes
(Peer reviewed; Journal article, 2022)The reduction of CO2 emissions has become a global concern. In this regard, the EU intends to cut CO2 emissions by 55% by 2030 compared to those of 1990. The utilization of shallow geothermal energy (SGE) in EU countries ... -
Decarbonization of the Iron and Steel Industry With Direct Reduction of Iron Ore with Green Hydrogen
(Peer reviewed; Journal article, 2020)Production of iron and steel releases seven percent of the global greenhouse gas (GHG) emissions. Incremental changes in present primary steel production technologies would not be sufficient to meet the emission reduction ... -
Effect of Iron Oxide Nanoparticles on the Properties of Water-Based Drilling Fluids
(Peer reviewed; Journal article, 2020-12)In recent years, several studies have indicated the impact of nanoparticles (NPs) on various properties (such as viscosity and fluid loss) of conventional drilling fluids. Our previous study with commercial iron oxide NPs ... -
Effect of Salts on Interfacial Tension and CO2 Mass Transfer in Carbonated Water Injection
(Journal article; Peer reviewed, 2019-02)Carbonated water injection (CWI) is a promising enhanced oil recovery (EOR) and CO2 sequestration method, which overcomes the problems associated with CO2 EOR. CO2 mass transfer and interfacial tension (IFT) are important ... -
