Trautz, Tommy Phelps, and Thomas M. Daley ABSTRACT The Frio Brine pilot is a closely monitored, small-volume (1,600 tons), short-duration experiment using injection of CO2 into a high-permeability brine-bearing sandsto...

Environmental considerations will probably change automobile fuels from gasoline and gas-oil to hydrogen (as fuel cell) in the future. Problems of fossil fuels include producing gaseous pollutants, such as NOx, CO, and even SO2 (from incomplete-hydrotreated fuels), which need catalytic converters and greenhouse gas emission (such as CO2, CH4, N2O) from the exhaust with a drastic effect on globa...

CO2-based enhanced gas recovery (EGR) is an appealing method with the dual benefit of improving from mature reservoirs and storing CO2 in subsurface, thereby reducing net emissions. However, injection for EGR has drawback excessive mixing methane gas, therefore, quality produced leading to early breakthrough CO2. Although this issue been identified as a major obstacle EGR, few strategies have s...

Geological CO2 sequestration is a key technology for mitigating atmospheric greenhouse gas concentrations while providing low carbon energy. Deployment of sequestration at scales necessary for a material contribution to greenhouse gas mitigation poses a number of challenges not encountered in current operations. At the basin scale, injection sites will not be as well characterized as current op...

Pre-salt reservoirs are among the most important discoveries in recent decades due to large quantities of oil them. However, high levels uncertainties related its gas/CO2 production prompt a more complex management, including use alternating water and injection (WAG) as recovery mechanism increase from field. The purpose this work is develop methodology manage cycle sizes WAG/CO2, analyze impac...

in this study, it was shown that how co2 and h2s were removed from a natural gas stream, using a nanofluid containing nanoporous graphene in diehanolamine (dea). before running the experiments, the appropriate values were chosen for the nanosheet dosage and the liquid and gas flow rates in the absorption experiments, which were performed in a laboratory scale wetted wall column. in the experime...

Water alternating gas (WAG) technique is used in the petroleum industry to inject carbon dioxide (CO2) into underground formations either for sequestration or enhanced oil recovery (EOR) processes. CO2 injection causes reactions with formation brine or aquifer and produces carbonic acid, the acid dissolves calcite and changes flow behavior significantly. Modeling and investigating effects of CO...

In industrial scale of Gas to Liquid (GTL) process in Fischer-Tropsch (FT) synthesis, a part of reactor outlet gases such as CO2 and CH4 as side reaction products, is usually recycled. In this study, the influence of CO2 and CH4 on the performance and selectivity of Co-Ru/Al2O3 catalyst is investigated by injection of these gases (0-20 vol. % of feed) to the feed stream. The effect of temperatu...

The Enhanced Oil Recovery (EOR) method aims to increase oil production. One of the EOR methods is CO2 injection. injection mechanism by expanding volume oil, reducing viscosity, and mobility ratio. purpose study was compare recovery factor gain in waterflood, Miscible Continuous injection, WAG with a three-dimensional simulation methodology using CMG Compositional software CW Field. From field,...

background: iran is located in the seventh rank in terms of co2 emissions resulting from the fuel combustion in the world. gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of co2 and ch4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....
