Application of Temperature Fall‐Off Interpretation Method in Superheavy Oil or Oil Sand SAGD Process

open access: yesGeofluids, Volume 2022, Issue 1, 2022., 2022
SAGD technology has been successfully and widely applied in the development of superheavy oil and oil sand projects. Before normal SAGD process, some preheating ways are often needed to realize interwell hydraulic connection, and this means that determining reasonable SAGD conversion timing from the preheating stage is an essential precondition for ...
