.../polymer flooding. While steam injection in heavy oil reservoirs can be very successful, more than 95% of the resource in Lloydminster is less than 10 m thick and, thus, is not amenable to steam injection due to excessive heat losses to the surrounding formations. However, EOR processes involving mild...

... L VIT Total VIT length, in m; Three VIT designs have been selected to run the study. All are double walled tubing with insulation in-between. The first design uses an insulator sleeve below the coupling to reduce heat loss at the connection. The other two other designs use intermediate...

... to be increased to compensate for the heat loss to the overburden and increasing accumulated heat ahead of the front due to interface extension and decreasing front velocity. In the CHI (Constant Heat Injection) model, heat is injected at a constant rate into the system, which provides heat for the growing steam...

... for ISR are also reduced compared to SAGD through elimination of surface and wellbore heat losses during energy transmission to the producing formation. Greater energy efficiency in ISR leads to lower carbon dioxide production and water requirements compared to SAGD. This paper presents a description...

... evaluated. The critical factor used to determine the efficiency of any completion type in the pre-heat process is the heat loss and heat exchange along the producer and injector wellbores and the completion components. This variation in thermal efficiency results from factors such as concentric versus...
