Paper presented at the Annual Technical Meeting, June 13–17, 1999
Paper Number: PETSOC-99-11
.... Based on these results, a new technical approach to enhancing fluid flow in reservoirs was formulated, and a full-scale field experiment in Alberta was initiated in December 1998. The field trial successfully showed that periodic application of large amplitude excitation to a porous medium experiencing...

Paper Number: PETSOC-99-32
... Abstract Conventional wisdom developed throughout many years in the oil industry indicates that a single, closed reservoir can have only one single well-defined water oil contact. Although the contact could appear in some instances to be tilted because of capillary effects, it is still a...

... of the oil displacement is caused by the flow of fingers of gas/steam rising counter-currently to the draining oil, rather than by the simple advance of a continuous steam chamber. The rising gas fingers raise the pressure in the reservoir above and this increase in pressure towards the top of the...

..., as a followup to existing technologies, or as a co-process where the advantages of high thermal efficiency are required. This is achieved by concentrating the energy required for oil mobilisation, recovery and thermal upgrading in the reservoir. Combined with clean technology design, THAI offers a...

... Abstract Many heavy oil and oil sand reservoirs are in communication with a gas cap and - in some cases - with a water sand. Depending on the density (° API gravity) of oil, the water sand could lie above or below the oil zone. Conventional thermal recovery methods - using vertical wells - in...

... part of the reservoir. In situ combustion, originally designed as flood patterns, has been practiced in the south of the field for about 20 years starting in 1973. Here the Driza formation is 450 m deep, oil gravity is 11 °API, and viscosity is approximately 9000 cp. Difficulties in production wells...

... operating trouble free for over a year. A plateau oil rate of about 100 m3/d has been sustained during this period, at an extremely efficient, Steam/Oil Ratio, (SOR), of just under 2.0. This paper briefly reviews the geology and the reservoir in which the wells are located, specifics of well design and...

... Crestar are normally conducted as the first phase of well stimulation. In undersaturated reservoirs, though, post fracture load fluids can be lost due to reservoir plugging, making the well uneconomic. Fortunately, the well is not permanently damaged and can be re-fractured with an oilbased fluid. Two...

... initiated during later periods of the process, an improved steam oil ratio is obtained without significant reduction in oil production rates and the total oil production. In this case, the injected noncondensable gas migrates to the upper part of the reservoir and does not prevents the growth of steam...
