The concept of steam-assisted gravity drainage (SAGD). Horizontal wells drilled in stacked pairs form the basic unit of SAGD project (top). Steam injected into the upper well melts surrounding oil (bottom). Gravity causes the mobilized oil to flow downward to the lower well for production. SAGD well pairs can be drilled to track depositional features or in patterns for optimal recovery (from Kopper et al., 2002).
