... with viscosity ratios ranging from 0.005 to 202.3 were used. Primary drainage and secondary imbibition displacements were carried out at different injection flow rates and unsteady-state relative permeability curves were constructed. It was found that relative permeability to both the wetting and the non-wetting...

... of the drainage rate of bitumen shows the square-root relationships to key reservoir parameters; it is unchanged from the past analytical models. These relationships are compared with the observed correlations of the scaled bitumen rates to these parameters in the numerous existing Vapex experimental data which...

... Abstract VAPEX, warm VAPEX and hybrid VAPEX rely on a combination of mass and heat transfer to reduce the heavy oil's viscosity sufficiently for it to flow via gravity drainage to the production well. In the last couple of years many combinations of vapour extraction and steam assisted gravity...

... Abstract Gravity drainage is the dominant production mechanism in fractured reservoirs, where injection of hydrocarbon gases is believed to improve oil recovery. This paper presents the results of an experimental study of the effect of injecting CO 2 into fractured media and its influence...

... years. The most promising of such processes that has been proposed is the Vapour Extraction or VAPEX process first proposed by Butler and Mokrys1. VAPEX is a solvent analogue of Steam- Assisted Gravity Drainage (SAGD) in which the viscosity- reducing effect of heat is replaced by the viscosity...

... of the steam, expands when the front is slowed down. Higher temperatures result in more rapid drainage from higher above the steam; this is why the blanket thickness does not increase in exact proportion to the volume of gas present. What About UTF?
