Results from Tasks 8 and 9 are presented. Task 8 addressed the cost of materials and manufacturing of the Downhole Methanator and the cost of drilling and completing the vertical cased well and two horizontal drain holes in the West Sak reservoir. Task 9 addressed the preliminary design of surface facilities to support the enhanced recovery of heavy oil. Auxiliary facilities include steam reformers for carbon dioxide-rich natural gas reforming, emergency electric generators, nitrogen gas generators, and an ammonia synthesis unit. The ammonia is needed to stabilize the swelling of clays in the reservoir. Cost estimations and a description of how they were obtained are given.
