... Abstract For cyclic steam stimulation (CSS) process of horizontal wells, previous studies mainly focused on the shape of heating zone and few scholars took heat losses from upper and lower reservoir rocks into consideration. However, it is hard to accurately describe the shape of heating zone...

... surfactant ionic liquid heat loss steam injection condensate hele-shaw cell interface Introduction Steam injection is a promising and efficient thermal recovery method where heat is transferred from the injected steam into the cold heavy oil phase to mobilize it by decreasing viscosity. However...

... is viable and commonly used to recover heavy oil and bitumen primarily by thermally altering oil viscosity and improving the displacement of heavy oil. However, there are significant heat losses before the steam reaches the heavy oil, in addition to the concerns of high cost and emission of greenhouse gases...

... Therefore, it is essential to limit heat losses to avoid irreparable damage to the well and overburden, if thermal processes are to be applied successfully in cold environments. Various studies for the design of wells in cold environment were conducted. Castanier 3 made an exhaustive...

... will use API 5-CT Grade L-80 for the inner tube and Grade J-55 for the outer tube. Collars are J-55. Coupling heat loss is minimized by placement of a coupling insulator fitted into the coupling cavity between two joints.
