In 1981, Ocelot successfully developed the Bantry gas field in southeastern Alberta with a unique slant-hole drilling technique in areas where surface topography made conventional drilling impossible. Ocelot initiated the project to develop the shallow (1050-1460 ft) Milk River and Medicine Hat gas reserves under the Tilley B manmade lake. Cheaper than offshore drilling, the slant-hole technique provided a means of reaching the reserves from the shore. Spudding the well at a 45/sup 0/ angle doubled the horizontal displacement achieved by conventional directional drilling to the depth required. A conventional single-stand, hydraulic rig - converted to drill slant holes - incorporated several new features that saved time in handling the pipe and in moving the rig between sites.
