The Wizard Lake D3 A pool went to blowdown in 2003, after achieving 86 % oil recovery from a vertical hydrocarbon miscible flood scheme. This paper describes some of the optimizations leading up to blowdown to increase gas sales and, in the initial stages of blowdown, to increase oil sales. A novel enhanced gas recovery scheme is also discussed, in which aquifer influx is diverted to another depleted pool through a horizontal well.
