.... A laboratory investigation was conducted to study the variables involved in the immiscible CO 2 displacement of heavy oils. Experiments were conducted in a 3-D physical model, packed with 18 ° API gravity crude oil, brine and crushed limestone. A total of 20 experiments were conducted using the 3-D physical...

..., and minimizing effect of heat loss to the cap/base rock). Using a scaled physical model of the Aberfeldy reservoir On Saskatchewan), experiments were performed to investigate steam flood recovery performance, using horizontal wells, for several different types of reservoirs, including those with a 20% net pay...

... by the economic model. rates. ne economic analysis indicated that a properly selected solvent would allow the production of heavy oil from a single well cyclic Several Parially scaled physical models were constructed and process in the Burnt Lake reservoir at potentially economic used to model the tuned solvent...

... physical models. lt has also been observed that by functions of temperature and decrease drastically with adding a non-condensible gas to the solvent vapour the increase in temperature. Of the thermal recovery processes, operating pressure of the process can be adjusted to the the SAGD technique[l) has...

... Abstract Steamflood experiments are carried out in a low-pressure scaled physical model to examine the effects of reservoir heterogeneity on oil recovery. Oil reservoirs are often composed of many layers of different permeabilities and porosities. This stratification can have significant...

... cylinders, with pressurised ellipsoidal cavities beneath the surface. Results will be used to assess the reliability of the analytical and numerical procedures used for hydraulic fracture analysis, by testing the predictions of the underlying physical models and by testing the admissibility...

... as a prelude to process variation or parametric studies.113 Three-dimensional, scaled, physical models have also been extensively used to investigate and pre- dict steamflood performance . 4'5 High-pressure models employ actual field crude oil and reservoir pressures and temperatures. Thus, they represent real...

... Abstract A scaled physical model representing one-twelfth of an inverted seven spot flooding pattern was used to study the various mechanisms of the steam driveprocess. The apparatus was designed to operate at pressures close to atmospheric and temperatures from 25.0 to 130.0 °C. A two...
