... Abstract The roles of foamy oil flow in cold production of heavy oils under solution gas-drive have been extensively studied in recent years. However, the mechanisms of foamy oil flow in porous media are still not fully understood. The viscosities of heavy oils and bitumen are often so high...

... heavy oil and tar sand/bitumen reservoirs. The application of the SAGD Process to oil sands that are in communication with water sand is investigated in this paper along with the effect of confined and unconfined water bearing zones. Heat balance calculations are also performed to establish...

... Abstract In many steam-based heavy oil/bitumen recovery processes, non-condensable or condensable gas is either present in the reservoir or is co-injected with steam. The distribution of non-condensable gas in the oil-depleted region can be very complex and may greatly influence process...

The second paper 1,2 reviewed the start-up and performance of the three Phase B well pairs and facilities which had produced 500,000 barrels of bitumen at that time, May, 1994. It also discussed the economics of a potential...

... throats. On the basis of this rationale, he postulated that the mobile gas and bitumen flowed as a single-pseudo phase with bubbles entrained in the bitumen. He reported that this simple foamy oil model had successfully predicted the pressure data observed in field. Loughhead and Saltuklarogu 3...

... gas channels at gas saturation greater than the critical saturation. Foamy oil flow is also a function of step duration, and for slow tests (greater than 24-hour step duration), foamy oil flow may be absent. Tests also reveal that the total bitumen recovery was extremely high, ranging from 35% to 50...

... and down-dip when the stress ratio is less than 1. There is no slip when the stress ratio equals to 1. Introduction Fluid or steam injection into bitumen oil sand reservoirs is often used to stimulate or assist viscous heavy oil production. However, fluid injection into the reservoirs is often done...

... Preparation The oil sand sample used in this study was from Imperial Oil's Cold Lake lease (434–442m, 6–21–65–4W4). The oil sands are semi-consolidated, berthierine-rich, and bitumen-poor. Bitumen in the sands was extracted using methylene chloride. Prior to bitumen extraction, almost all sand grains...

... crude oil production is approximately 320,000 m 3 /d. Of this amount, 50 % is comprised of heavy crude and bitumen. While bitumen demand has been essentially flat since the mid to late ‘80’s, heavy oil production has doubled from 56,000 m 3 /d to 112,000 m 3 /d in the last 10 years 1 . Why heavy oil...
