Canadian operator succeeds in slant-hole drilling project
Describes the first application of slant-hole drilling to shallow gas reservoirs. The project required development of new downhole drilling techniques and equipment, as well as an innovative rig design. Ocelot is one of the largest producers of natural gas from southeastern Alberta's shallow Milk RiverMedicine Hat formations. With slant-hole drilling, multiple wells can be drilled from a single surface location. Also, pipelining costs are reduced and field operations are simplified. Diagram shows how, on multiple well sites, well centers are spaced 50 ft apart, parallel to the lake shore to allow rig movement. Concludes that the program was successful and proved slant-hole drilling could be a viable method of developing shallow gas reserves which would be otherwise unrecoverable due to topography. Future projects are being planned around topography and from multiple well sites to reduce land usage.
