Abstract

The pressure at which cold water is initially injectable into an oil sand formation is determined. In the practice of steam-assisted gravity drainage in that formation, steam is injected at a pressure greater than the cold water initial injectivity pressure but no more than 1500 kPa grater than that pressure.
