CALGARY, ALBERTA -- (Marketwire) -- 02/04/13 -- Yoho Resources Inc. ("Yoho" or the "Company") (TSX VENTURE: YO) is pleased to provide an update of Duvernay drilling and completion operations at Kaybob, Alberta.

Kaybob, Alberta

At Kaybob, Yoho operated the drilling and completion of the first two horizontal Duvernay development wells from a pad site at 15P-16-62-21 W5 targeting the Devonian Duvernay shale. The first well located at 14-21-62-21 W5 (75% working interest) was drilled to a measured depth of 4,943 meters. The horizontal lateral was 1,536 meters in length within the Duvernay shale formation. The well was drilled and cased over 33 days at a cost of approximately $4.5 million. Well completion operations commenced in late December 2012 using a "plug and perf" completion method. The well was fracture stimulated in 15 stages with 51 perf clusters using 2,217 tonnes of sand and 18,940 m3 of completion fluid. Following the fracs, the pumpdown bridge plugs were drilled out with a coiled tubing unit and production tubing was snubbed in. The total estimated cost of the completion is approximately $6.6 million, bringing the total cost to drill, complete and test the well at approximately $11.1 million.

During initial clean-up, the 14-21 well flowed at restricted rates of up to 8.5 MMcf (239.4 e3m3) per day (approximately 2,508 boe per day including condensate and natural gas liquids). At the end of the 86 hour flow period, the well was producing at a rate of 6.3 MMcf (177.4 e3m3) per day (approximately 1,860 boe per day including condensate and natural gas liquids) up production tubing at flowing tubing pressures of 8,912 kPa and flowing casing pressure of 8,812 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 665 barrels (103 m3) per day or 106 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 field condensate and plant liquids, is estimated to be 155 barrels per MMcf of raw gas. At the end of the flow period, approximately 11,910 barrels (1,880 m3) (10%) of completion load fluid had been recovered. Total fluid production rate (completion load fluid and hydrocarbon liquids) at the end of the test period was 2,667 barrels per day, of which 75% was completion load fluid.

The second well located at 1-16-62-21 W5 (75% working interest) was drilled to a measured depth of 4,355 metres. The horizontal lateral was 983 metres in length within the Duvernay shale formation. This well was planned as a substantially shorter lateral due to regulatory spacing regulations. The well was drilled and cased over 32 days at a cost of approximately $4.2 million. Well completion operations also commenced in late December 2012 using a "plug and perf" completion method. The well was fracture stimulated in 11 stages with 38 perf clusters using 1,382 tonnes of sand and 13,031 m3 of completion fluid. Following the fracs, the pumpdown bridge plugs were drilled out with a coiled tubing unit and production tubing was snubbed in. The total estimated cost of the completion is approximately $4.8 million, bringing the total cost to drill, complete and test the well to be approximately $9.0 million.
