WebNov 6, 2024 · The gamma plots in the SAGD producers show cleaner sands in the same well pairs 1 through 4. AOC has reported increasing Breccia above the producer elevation in well pairs 5 through 7, therefore it is hard to attribute the SAGD steam chamber conformance to either FCDs or the reservoir alone. WebSAGD (Steam Assisted Gravity Drainage) is a thermal recovery process for production of nearly immobile bitumen from the deeper oil-sand formation. In this method, two parallel horizontal wells are drilled near the reservoir bottom, one about 5 m higher than the other. Steam injected through the upper well provides heat to the heavy oil to reduce its viscosity.
