...Experimental Procedure Model Packing and Bitumen Saturation Bitumen Properties The bitumen sample used in the SAGD and DME-SAGD experiments was taken from a thermal bitumen production site in Alberta, Canada. Its molecular weight was 540 g/mol. The original asphaltene content...

... transfer with the perpendicular condensate flow to the SCI cannot be neglected ( Sasaki et al., 2001 ; Ito and Ipek, 2005 ). It is reported that the viscosity difference between heavy oil/bitumen and solvent/steam permits the latter to finger into the oil phase, depending on the injection temperature...

In this research, three VAPEX experiments are carried out in a physical model using bitumen and three solvents...

... formations with the temperatures required for economic power generation, in situ bitumen producers have access to existing SAGD wells within mature reservoirs that are at shallow depths and high temperatures. The thermal energy from just one SAGD well can produce enough electricity to power thousands...

... Abstract Suncor's Firebag Steam Assisted Gravity Drainage (SAGD) project has been in operation since 2004 and a total capacity of 215 mbbls/d of bitumen. 1 It is Suncor's largest in situ operation, with approximately 600 wells. Maximizing the value of the capital investment and operating...

... Abstract Thermal-based recovery techniques will continue to be used in bitumen and heavy oil recovery. Among them, electromagnetic (EM) heating is promising, especially in situations in which there are technical and environmental issues with steam-based methods. To design the EM process...

... Abstract In this work, we studied the phase equilibrium of the normal-hexane, water, and Mackay River bitumen ternary system at operating conditions applicable to the solvent-assisted thermal recovery process. The viscosities of the hydrocarbon-rich (oleic) and water-rich (aqueous) phases were...

... Abstract Injection or co-injection of solvents has been proposed as an in-situ recovery mechanism for bitumen ( Gupta et al., 2002 ). Solvent-based recovery schemes have several potential advantages over steam-based schemes such as SAGD. These benefits include lower GHG emissions and water...

The injected fluid first displaces bitumen in the form of an advancing finger, forming a condensate-bitumen interface which is slowly advancing towards the production port at the bottom end of the model. Hot water initially displaces bitumen...

..., for a recursive structure, the ARX model structure has the highest prediction accuracy in a seven-day multi-step ahead prediction of bitumen and water rates. In the work of Vembadi et al.

... Abstract Steam assisted gravity drainage (SAGD) is an effective thermal recovery method for enhanced bitumen recovery. However, the success of SAGD operation depends on several factors. Reduction in gas and steam production is a crucial factor to achieve a successful SAGD operation. Autonomous...

... to maintain the pressure and assist the bitumen to flow towards the producer well. The partial pressure of the steam is lowered, and consequently the temperature is being decreased from 230°C to about 160°C. This process is known as steam and gas push (SAGP) ( Butler, 1999 ). As the non-condensable gases have...
