... screening of a range of potential gas injectants (such as CO 2 , enriched hydrocarbon gas, N 2 , or H 2 S) through the use of readily available gas and oil properties. The methodology has been applied to numerous reservoirs worldwide. An overview of the methodology is provided along with an illustration...

... studies of the carbon dioxide injection process, the Ivanić oil field was chosen as the first candidate for the application of this EOR method. In order to rebuild the Gamma 2/4 reservoir pressure before the pilot project, injection of water started in 2001. The WAG CO 2 process is being conducted...

... suggest that having a small (and yet relatively significant) C 5 + fraction could have a large effect on reducing the MMP to considerably below the predicted values from existing correlations. This paper aims at investigating possible benefits for miscibility and CO 2 EOR flooding with impurities...

... Abstract Carbon Dioxide (CO 2 ) foam has been widely studied in connection with its application in EOR. This paper reports an experimental study concerning CO 2 foam propagation in a surfactant saturated Bentheim sandstone core and the subsequent liquid injection with the aid of X-ray Computed...

... and export to market. Gas composition was assumed to be 75% sweet natural gas, 20% H 2 S and 5% CO 2 . The acid gas components are treated as waste: the CO 2 is vented and the H 2 S is converted to solid sulphur blocks, stored above ground, and turned over to the host government at the end of production...

... Abstract Carbon Dioxide (CO 2 ) has been recognized as a preferred miscible solvent for Enhanced Oil Recovery (EOR) methods. Miscible flooding by CO 2 has proven its positive effectiveness through numerous laboratory and field projects. The main goals of this study are to provide microscopic...

... criteria had been completed to select appropriate method which could be applied in certain field. In this study, we present gas injection program in West Java to obtain better recovery of the mature field/brownfield. The gas injection program include natural gas such as ethane, propane and CO 2 flooding...

... and temperature, using a 3D polynomial surface. In the field, this information can then be used to predict production/injection performance and different operational problems related to asphaltene deposition in CO 2 miscible injection and also CO 2 sequestration process in a depleted oil reservoir...

... prices, the process has lost some of its initial attraction. For reducing the solvent cost, the injection of CO 2 as a non-condensable gas appears to be an attractive alternative. The advantage of this low cost alternative is that the solubility of CO 2 in heavy oils is significantly higher than...

... Abstract When light-oil reservoirs are considered for miscible gas injection processes (with CO 2 or hydrocarbon gases), more often the potential of asphaltene precipitation is either overlooked or not anticipated for two seemingly compelling reasons: first, the asphaltene content in most...

... Abstract BP has accepted the growing consensus that there may be a link between emissions of anthropogenic CO 2 and climate change and that it is appropriate to take prudent precautionary measures now. Improvements in energy efficiency and more generally in energy management represent the best...

.... Environmental considerations also favour IOR projects, since they can reduce the need for new green field developments, provide a means of utilising unwanted associated gas production and ultimately a disposal route for CO 2 . Identifying appropriate projects in a field portfolio can be a difficult task...

... Abstract In meeting the challenge to improve oil recovery through implementation of IOR techniques, Dulang field was selected to study the possibility of CO 2 injection as a potential recovery method. Dulang was chosen as the candidate because of the complete suite of information on this field...

... in 1999, with some 1.3 million tonnes of CO 2 emissions avoided in year 2000 alone. Miscible displacement is expected to add around 6 million barrels to ultimate recovery from the Corallina reservoir, and use of stored gas as fuel is expected to achieve significant reductions in operational expenditure...

... Abstract This paper is based on laboratory research which is focused on the potential applications of CO 2 gas, existing in different reservoirs in Indonesia, especially in the D-Alpha Gas Reservoir in Natuna Sea. CO 2 gas as an injection fluid into oil reservoirs has been a well recognized...

... Abstract Miscible CO 2 gas injection has nowadays become one of the most important enhanced oil recovery (EOR) processes. For optimal displacement efficiency, CO 2 flooding should be conducted at pressures greater than a minimum miscibility pressure (MMP), which is a function of temperature...
