Greenhouse gas (GHG) emissions from oil and gas systems are an important component of the GHG emission inventory. To assess the carbon emissions from oilfield-produced water under atmospheric conditions correctly, in situ detection and simulation experiments were developed to study the natural release of GHG into the atmosphere in the Shengli Oilfield, the second largest oilfield in China. The ...

Global climate change due to CO2 emissions is an issue of international concern that primarily attributed to fossil fuels. In this study, Genetic Algorithm (GA) is used for analyzing world CO2 emission based on the global energy consumption. Linear and non-linear forms of equations were developed to forecast CO2 emission using Genetic Algorithm (GA) based on the global oil, natural gas, coal, a...

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

During tertiary miscible gas injection direct contact between gas and oil can be prevented by water surrounding residual oil. The principal aim of our study is to assess the importance of this waterblocking phenomenon in multicomponent gas injection. We study this process using a multicomponent porescale model. Light components in the gas dissolve in the water and diffuse through the water to r...

Title of dissertation: EXPERIMENTAL AND THEORETICAL INVESTIGATION OF OIL RETENTION IN A CARBON DIOXIDE AIR-CONDITIONING SYSTEM Jun-Pyo Lee, Doctor of Philosophy, 2003 Dissertation directed by: Professor Reinhard Radermacher Department of Mechanical Engineering In a closed loop vapor compression cycle, a small portion of the oil circulates with the refrigerant flow through the cycle components w...

Pyrolitic conversion of lignocellulosic biomass, such as switchgrass and other agricultural residues, to bio-fuels is being considered for national energy security and for environmental advantages. Bio-oil, syngas and bio-char were produced and characterized from switchgrass at 400, 500 and 600 0C by pyrolysis. Bio-oil yield increased from 22 to 37%, syn-gas yield increased from 8 to 26%, and b...

Oil shale is a sedimentary rock that contains kerogen, a fossil organic material. Kerogen can be heated to produce oil and gas (retorted). This has traditionally been a CO2-intensive process. In this paper, the Shell in situ conversion process (ICP), which is a novel method of retorting oil shale in place, is analyzed. The ICP utilizes electricity to heat the underground shale over a period of ...

CO2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. In this study, the lower part of Es1 reservoirs in Pucheng oilfield was introduced as the target reservoir. By studying the minimum miscible pressure in CO2 flooding, the reservoir could achieve miscible flooding. Long core displacement experiments prove...
