POSITIVE INITIAL TESTING RESULT AT TERRAWEST’S PROPERTY IN CHINA
Thursday, 07 April 2011
Petromin is pleased to announce that TerraWest has completed initial testing of the first 2010 pilot production well at Liuhuanggou Project. Terrawest has encountered a productive CBM interval in the LHG 10-01 pilot production well, and gas was flared.
Vancouver, British Columbia, April 6, 2011 –Petromin Reources Ltd (“Petromin” or “the Company” ) is pleased to announce that TerraWest Energy Corp. (“Terrawest”) has completed initial testing of the first 2010 pilot production well on its Liuhuanggou coalbed methane (“CBM”) lands in Xinjiang, the People’s Republic of China (“China”).
TerraWest has encountered a productive CBM interval in the LHG10-01 pilot production well. The productive interval was encountered within the Jurassic Xishanyao (“J2X”) formation at a depth between 611 and 665 meters. Initial CBM flow came from a 31.25 meter perforated interval of the J2X #14-16 coal seams, including #14 seam interval of 16 meters thickness, which TerraWest has not yet fracture stimulated. Gas was flared. The LHG10-01 well has a total depth of 720 meters and intersected over 65 meters total thickness of J2X coal seams.
The LHG10-01 well is located approximately 4 to 5 kilometers west of well LHG08-01 which produced water and flared produced CBM in testing in 2009. LHG10-01 was drilled as a pilot production well for the J2X coal seams in the western portion of the Liuhuanggou Project area, where coal seams are thick and gas contents relatively high.
The Liuhuanggou Project pilot production program currently underway includes drilling, well testing, and fracture stimulation of target intervals after testing. The program comprises a total of 10 wells of which three vertical wells have been drilled, logged and cased. LHG10-01 was the first of the 2010 wells to undergo initial gas flow and pump testing. Such testing provides the basic engineering data to support further well completion work including fracture stimulation.
Wells LHG10-02 and LHG10-03 are to be tested after spring break-up. These two wells will test the Jurassic Badaowan (J1B) formation including multiple coal seams and gas-bearing surrounding rocks. The combination of multiple coal seams with aggregate thickness of approximately 30 metres and other potentially productive intervals including shale provides a unique natural gas target of great merit.
The Liuhuanggou Project covers an area of approximately 653 square kilometres (255 square miles; 163,200 acres). The project is located in the highly prospective southern Junggar Basin of Xinjiang, western China, and lies adjacent to the capital city of Urumqi, a burgeoning energy centre for the Junggar region which is rich in hydrocarbons and an active producer of petroleum, natural gas and coal. The CBM potential of the Junggar Basin has attracted international interest from such CBM majors as BP Corporation and Dart Energy Limited which are undertaking early stage exploration activities.
As at the date hereof, the Company held 22.28% of the current issued common shares and preferred shares in the capital of TerraWest. TerraWest is the Operator and holds a 47% interest in the PSC with CUCBM holding 53%. Under the terms of the PSC, CBM is defined as all gas stored in four (4) named geologic formations of Jurassic age to a depth of 1,500 meters.
Mr. Arthur Ross Gorrell, Chief Executive Officer of the Company, said “Flowing CBM from this interval of the J2X encountered at the LHG10-01 adds important basic reservoir information to our project database, as the scope of our pilot program at Liuhuanggou continues to expand.”
