Steam-assisted gravity drainage (SAGD) methods have been widely applied in oil-sands
exploitation globally. SAGD processes are effective only after thermal and hydraulic …

Coupled thermo-hydro-mechanical analyses in heavy oil reservoirs are essential for
engineers to evaluate and optimize the field operations in terms of safety, economy, and …

Mudstone stringers in an oil sand reservoir can significantly affect the propagation of the
steam chamber in the process of steam-assisted gravity drainage (SAGD). The micro …

Steam assisted gravity drainage technology has been widely applied to bitumen recovery in
Karamay, northwest China. Steam circulation prior to production is designed to establish the …

The thermal recovery is facing the challenge of improving quality and efficiency. Steam-
assisted gravity drainage (SAGD) steam circulation has a profound implications for the …

There are only a few related studies focused on the steam assisted gravity drainage (SAGD)
dilation start-up technology (termed as dilation start-up in this paper), especially with true …

The techniques of natural gas production from hydrate reservoir are significantly different
from those used for conventional oil and gas resources, because the virgin hydrate will …

The SAGD start-up process normally circulates steam in both the injector and producer,
which consumes a large amount of steam, requires the high cost of high-temperature …

Viscosity-temperature behavior is important for the thermal recovery of bitumen: firstly, it is a
criterion for evaluating the evolution of mobility with temperature, which affects oil …

Water injection in SAGD well pairs has rapidly developed to improve the circulation
preheating efficiency and the steam chamber propagation speed. However, a key problem is …
