HOUSTON, Apr. 19 -- Trilogy Energy Corp., Calgary, reported gas-condensate production from its second horizontal Devonian Duvernay shale well and drilled three horizontal Montney oil wells, all in the Kaybob, Alta., area 150 miles west-northwest of Edmonton.
The Duvernay well has a bottomhole location in 3-13-060-20w5 at 4,866 m measured depth with a 1,391-m lateral in Duvernay shale. Trilogy managed drilling and completion in 50 days at $6.5 million under a joint venture with Celtic Exploration Ltd. and Yoho Resources Inc.
Tied in since Apr. 10, the well was flowing up 7-in. casing at 5.2 MMcfd of sweet natural gas and 390 b/d of natural gas liquids including 180 b/d of 56° gravity condensate, and 1,450 b/d of water. The production rate may improve when production tubing is run and load water recovered.
The expected gas liquids yields is 75 bbl/MMcf including 35 bbl/MMcf of condensate.
Trilogy fracture stimulated the well in 31 perforated intervals in 12 stages along the lateral with 2,300 tonnes of sand and 138,600 bbl of slick water. The “plug and perf” completion technique incorporated perforation clusters (2 and 3 per stage) to stimulate the well. Only 26% of the completion water has been recovered.
Completion costs have totaled $11 million. Trilogy expects major cost savings on subsequent wells as the 3-13 was the first to use “plug and perf” in the Duvernay.
Trilogy expects to participate in one more Duvernay shale well in 2011. The company owns 168,409 gross acres and 138,173 net acres with Duvernay rights at Kaybob and surrounding areas.
Meanwhile, Trilogy added three horizontal Montney oil wells to its first two horizontal completions in the Kaybob Montney oil pool. The 9-1, 13-2, and 5-17 wells are expected to be treated and completed in April and May.
Trilogy is developing an accelerated drilling program as a result of the early success at Kaybob Montney, subject to board approval, that would result in an increase in 2011 capital spending and production.
