Yoho operated the drilling and completion of one well, and participated in the drilling and completion of a second well in the Company's Duvernay program at Kaybob, Alberta.
The first well located at 16-04-62-21 W5 (50% working interest) was drilled to a measured depth of 4,740 meters. The horizontal lateral is approximately 1,300 meters in length within the Duvernay shale formation. The well was drilled and cased at a cost of approximately $5.0 million. The well was subsequently fracture stimulated, the pumpdown bridge plugs were drilled out with a coiled tubing unit, production tubing was snubbed in and a flow test was conducted. The total gross estimated cost of the completion is approximately $7.0 million, bringing the total gross estimated cost to drill, complete and test the well to $12.0 million.
During initial clean-up conducted up casing, the 16-04 well flowed at rates up to 4.6 MMcf (130 e3m3) per day (approximately 1,200 boe per day including condensate and natural gas liquids). The well was also flowing completion fluid at rates of 60 bbls (10 m3) to 120 bbls (20 m3) per hour. At the end of the 117 hour total flow period, the well was producing up tubing at a restricted rate of 2.5 MMcf (71 e3m3) per day (approximately 670 boe per day including condensate and natural gas liquids) at flowing tubing pressures of 8,500 kPa and casing pressure of 19,800 kPa. In addition to the natural gas production at the end of the flow period, the well was producing field condensate at a rate of 230 barrels (37 m3) per day or 92 barrels of field condensate per MMcf of raw gas. Additional natural gas liquids are anticipated to be recovered at the gas processing facility. Total liquids yield from this well, including both stabilized condensate and plant liquids, is estimated to be 120 - 130 barrels per MMcf of raw gas. At the end of the flow period, approximately 23,900 barrels (3800 m3) (23%) of completion load fluid had been recovered. These flow rates were achieved while continuing to flow back 60 bbls per hour (10 m3 per hour) of load fluid.
The second well, located at 16-02-60-19 W5 (33.33% working interest) and operated by a third party, was drilled to a measured depth 4,710 meters. The horizontal lateral was approximately 1,300 meters in length within the Duvernay shale formation. The well was drilled and cased at a cost of approximately $5.0 million. The well was fracture stimulated and the pumpdown bridge plugs were drilled out with a coiled tubing unit and production tubing was snubbed in. The total gross cost to drill, complete and test this well is estimated at less than $12 million.
During initial clean-up, the 16-02 well flowed at rates up tubing of up to 3.6 MMcf (100 e3m3) per day (approximately 900 boe per day including condensate and natural gas liquids). In addition to the natural gas production during the flow period, the well was producing field condensate at rates of up to 300 barrels (48m3) per day or 83 barrels of field condensate per MMcf of raw gas. Additional natural gas liquids are anticipated to be recovered at the gas processing facility. Total liquids yield, including both stabilized condensate and plant liquids, is estimated to be 100 -110 barrels per MMcf of raw gas. At the end of the flow period, approximately 14,000 barrels (2,230 m3) (10%) of completion load fluid had been recovered. The well was producing load fluid at a rate of 55 - 75 bbls per hour (9 - 12 m3 per hour) during the test period.
Both wells are tied into gathering systems and both will be on stream upon the completion of surface facilities which are currently being constructed. Yoho is very pleased with the strong early flow characteristics from these wells and looks forward to the application of technologies used in the completion of these wells to longer laterals in future wells.
