Describes how shallow 260- to 660-ft (80- to 200-m) oil sands were developed by drilling highly deviated wells using a drilling rig with a 45 degree-slanted mast. Combination of shallow depth and unconsolidated bituminous sands presented unique drilling problems to obtain long horizontal sections. Presents graphs showing breakdown of well depth vs. days, the well bore program, and a well completion schematic. Designed for both vertical and slant-hole drilling, the hydraulic rig increased drilling and completion time and costs. Concludes that the information, techniques, equipment design, and expertise gained from drilling the 3 horizontal wells are invaluable in the quest toward commercial production of bitumen by in-situ methods. Suggests that by drilling to 2,082 ft DD (635 m) with 1,246 ft (390 m) of hole horizontal in the oil sands, a significant advance in very shallow formation drilling has been achieved.
