... coefficient in heavy oils are relatively scarce due to the tedious nature of diffusivity measurements, The main objective of this work was to develop a simple experimental technique for measuring gas diffusion coefficients in heavy oils. Diffusion coefficients of carbon dioxide and methane were measured...

... Abstract High acid gas content streams, consisting primarily of carbon dioxide, hydrogen sulphide or a combination of both are commonly generated as a by-product of the sweetening process used to bring many produced gases and solution gases to pipeline specifications for sales and transport...

... Abstract In the immiscible displacement of oil by carbon dioxide gas, the solution and diffusion of carbon dioxide are important factors that determine the efficiency of the process, since an increase in the carbon dioxide solubility and diffusivity into oil leads to an increase in oil...

... in the fracture proppant pack 4,5 that can impair production. Treatment designs utilizing combinations of fluids with nitrogen or carbon dioxide and even binary foams where nitrogen and carbon dioxide are used, reduce this problem. The addition of nitrogen and/or carbon dioxide provides a non combustible gas...

... Abstract Immiscible carbon dioxide floods have been shown to hold promise for the recovery of moderately heavy oils of Alberta and Saskatchewan by both laboratory and field studies. This paper addresses the important question of the effect of carbon dioxide purity on the process efficiency...

... the results from laboratory studies which show that some clasts are richer in carbonates. These carbonates react with aluminosilicates in the clasts under steaming conditions to generate formation damaging products like swelling clays and carbon dioxide, Swelling clays can damage the formation by plugging...

... for the low pressure immiscible carbon dioxide water-alternating- gas (WAG) flooding process, employing a linear and a two-dimensional scaled model. Runs carried out to simulate the Aberfeldy field in a linear model were repeated in a two-dimensional model for the same pressures and WAG ratios, 50...

... procedures with particular emphasis on individual mechanisms. In this work pressure cycling a dead bitumen was compared to a direct steam drive. Subsequently, the addition of carbon dioxide to the steam was considered during the reservoir pressure build up portions of the pressure cycles. Then the study...

... Abstract The use of carbon dioxide as an oil recovery agent in petroleum reservoirs has been investigated for many years. Both laboratory and field studies have established that carbon dioxide can be an efficient oil displacing agent. The purposes of this research were to (1) study...

... Abstract The effect of CO 2 on carbonate rock during carbon dioxide flooding of petroleum reservoirs was investigated using dolomite cores. The studies were made at several pressure levels to determine the effects of pressure on the interaction of CO 2 and dolomite. Fifteen cylindrical...
