As one the most important recovery mechanisms of steam-assisted gravity drainage (SAGD), gravity drainage is largely dependent on the inclination angle of the steam chamber edge. The existence of solution-gas causes an ellipsoid-shaped chamber that has small inclination angle at the bottom, which leads to inefficient gravity drainage …
It also shows that if fluid energy storage is not used (TES = 0 h), only a capacity factor of 3% is achievable, whereas with 1 h of thermal energy storage, we can reach a capacity factor of only 10%. In addition, the LCOE between 6 and 12 h is similar, and with <6 h of TES, the cost (in $/kWh) increases.
Summary. Proper pipe alignment and drainage means observing a few simple rules: Steam lines should be arranged to fall in the direction of flow, at not less than 100 mm per 10 metres of pipe (1:100). Steam lines rising in the direction of flow should slope at not less than 250 mm per 10 metres of pipe (1:40).
