WebJan 1, 2024 · Steam-assisted gravity drainage (SAGD) is a challenging enhanced oil recovery technique that requires proper parameterization in terms of well geometry and steam injection parameters as these parameters are highly dependent on the reservoir geology and fluid characteristics (e.g., net pay variation, water saturation). WebIn steam-assisted gravity drainage (SAGD) operations, pairs of stacked horizontal wells are drilled into the reservoir about 400 metres beneath the surface. The top well injects steam to heat the bitumen, which separates from the sand and collects with the produced water in the lower well, approximately five metres below.
