Dimethylether-A Promising Solvent for ES-SAGD
SPE Canada Heavy Oil Technical Conference, 2018Abstract Co-injection of solvent with steam is one of the promising methods to recover bitumen. The major operational cost for these projects is related to steam generation, water treatment and solvent. Propane and butane have shown desirable performance as solvent.

Re-Examination of Fingering in SAGD and ES-SAGD
SPE Canada Heavy Oil Technical Conference, 2016Abstract Steam-Assisted Gravity drainage (SAGD) is a popular approach for oil sands recovery, in which a steam chamber is developed inside reservoir with heated up bitumen flowing downwards along the edge of the steam chamber to production well by gravity.

Investigation of Emulsion Flow in SAGD and ES-SAGD
SPE Heavy Oil Conference Canada, 2012Abstract Expanding Solvent-Steam Assisted Gravity Drainage (ES-SAGD) was invented to enhance SAGD performance by reducing energy use while increasing oil production rates and recovery factor. ES-SAGD involves co-injection of solvent and steam.

ES-SAGD; Past, Present and Future
SPE Annual Technical Conference and Exhibition, 2009Abstract North America's long-term energy future depends heavily upon the Athabasca oilsands. Only 15% of these deposits are at mineable depths (<90m) and thus 85% of the oilsands (232 billion bbl recoverable reserves) must be recovered using in-situ techniques.

Simulating the ES-SAGD Process With Solvent Mixture in Athabasca Reservoirs
Journal of Canadian Petroleum Technology, 2008Abstract The ES-SAGD process was developed to improve the energy and oil drainage efficiency of the SAGD process. The idea of the ES-SAGD process is to co-inject solvent with steam and the co-injected solvent mixes with the bitumen to further reduce the viscosity of the heated bitumen along the boundary of the steam chamber thus enhances

Compositional Mechanisms in SAGD and ES-SAGD With Consideration of Water Solubility in Oil
SPE Canada Heavy Oil Technical Conference, 2016Abstract Experimental data have shown that the solubility of water in the oleic (L) phase (xwL) can be significant at elevated temperatures. However, xwL was not properly considered in prior studies of SAGD and ES-SAGD. The main objective of this research is to present a detailed study of compositional mechanisms in SAGD and ES-SAGD ...

Laboratory Experimental Testing and Development of an Efficient Low-Pressure ES-SAGD Process
Canadian International Petroleum Conference, 2008Abstract Certain Athabasca reservoirs have low pressures because they have been depleted due to production of over-laying gas. Other reservoirs are naturally occurring low-pressure shallow bitumen reservoirs. Hence, there is a need to develop or investigate recovery processes under which such low-pressure reservoirs

Rigorous coupling of geomechanics and thermal-compositional flow for SAGD and ES-SAGD operations
SPE Canada Heavy Oil Technical Conference, 2015Abstract Steam Assistant Gravity Drainage (SAGD) is widely used to recover heavy oil and bitumen reservoirs. Typical SAGD operations involve a pair of horizontal wells separated vertically. Steam, or a steam-solvent mixture (e.g., Expanding- Solvent SAGD), is injected into the upper well to form a steam chamber and mobilize oil, which ...

SPE Heavy Oil Conference-Canada, 2014
Abstract Efficient recovery of heavy oil and bitumen in western Canada has widely been applied with thermal-based processes. The well-known Steam-Assisted Gravity Drainage (SAGD) takes advantage of the strong dependency of bitumen viscosity on temperature ranging from 10 to 250 °C.

Pentane as a Potential Candidate for ES-SAGD and Hybrid Processes: Its Phase Behaviour with Bitumen
SPE Heavy Oil Conference-Canada, 2014AbstractSteam-assisted gravity drainage (SAGD) is a promising method for producing oil sand in Alberta; however, it has been suffering from high energy and water consumption and significant greenhouse gas (GHG) emissions. Solvent-based processes represent an alternative to steam-based processes but they have their own drawbacks.
