dc.description.abstract	Steam circulation in the early stages of Steam-Assisted Gravity Drainage (SAGD) is crucial for establishing hydraulic communication between the injector and producer well and the future development of the steam chamber. Steam is the carrier of enthalpy to the reservoir and thus, the evolution of pressure, temperature, and steam quality is important for heat transfer efficiency. In the research reported here, the steam circulation phase of a SAGD well pair is examined in detail taking into account heat loss around the wellbore in the vertical/build section and heat transfer and fluid losses in the lateral section of the well pair. In the model developed, well bore hydraulics is also accounted for by using a discretized wellbore model within a fully implicit coupled thermal reservoir simulator. Field data from the circulation phase was history-matched to calibrate the model and subsequently, five different completion designs were examined to evaluate their thermal efficiency. The results show that completion design impact heat transfer and thermal efficiency of the circulation process.	en_US
