Water-Soluble Solvent as an Additive to Steam for Improved SAGD
, 2017 Coinjection of solvent with steam results in lower chamber-edge temperatures than those in steam-assisted gravity drainage (SAGD), which enable to decrease heat losses to the overlying formation rocks.

Reactive Thermal Reservoir Simulation: Hydrogen Sulphide Production in SAGD
, 2011 In SAGD, steam is injected into a bitumen bearing oil sands formation. Steam temperature ranges from about 200 to 260°C and at these temperatures, bitumen undergoes aquathermolysis yielding acid gases such as hydrogen sulphide and carbon dioxide.

Geomechanical and Thermal Simulation of ES-SAGD Process
, 2011 Overlying top water and gas thief zones have a detrimental effect on the Steam-Assisted Gravity Drainage (SAGD) recovery process since steam penetrates into these zones which results in great heat loss.
