CS Resources is currently undertaking the construction of an 800 m3/day (5,000 bpd) thermal project near Senlac, Saskatchewan. The Senlac Thermal Project will use a steam assisted gravity drainage (SAGD) process to recover as much as 3.2 е6 m3 (20 mmbbl) of 13°API oil from a Dina channel sand.

This paper discusses some of the production and facility engineering issues arising in this full scale SAGD scheme. Compared to primary or conventional thermal operations, some of the unusual aspects are: very high injection and production rates from individual wells; the need to manage the large amount of heat in the production stream; and a pronounced interdependence between the various project components. Reservoir description, production forecasting, and facility optimization are briefly discussed.
