Paper presented at the Annual Technical Meeting, June 7–9, 1998
Paper Number: PETSOC-98-63
... 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 by...

Paper Number: PETSOC-95-64
... 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...

... 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. A...

... 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...

... insight into combinations of operating 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...

... Abstract Phase behavior tests were carried out on a Nisku crude oil (a candidate reservoir for nitrogen flooding) with nitrogen and nitrogen mixed with carbon dioxide or propane. These measurements were carried out in a batchwise multiple contact mode to simulate what occurs when gas displaces...

... Abstract For several years carbon dioxide (CO 2 ) has been added to fracturing fluids at concentrations of 100 to 500 cubic feet per barrel (18 to 90 m 3 /m 3 ), to assist in post-treatment clean-up. In some instances, this has eliminated swabbing after treatment. A new technique increases the...
