HRT concludes drillstem test of well 1-HRT-9-AM, in the Solimões Basin11:30 EDT Wednesday, September 12, 2012RIO DE JANEIRO, Sept. 12, 2012 /CNW/ - HRT Participações em Petróleo S.A. (the "Company" or "HRT") (BM&FBOVESPA: HRTP3, TSX-V: HRP) announces that its subsidiary HRT O&G Exploração e Produção de Petróleo Ltda. ("HRT O&G") has concluded the drillstem test in well 1-HRT-9-AM, block SOL-T-191, in the Solimões Basin.The test, carried out in the Juruá Formation reservoir, with a net-pay of 36.4 meters, was successfully concluded on September 7. An interval from 2,769.6 to 2,794.4 meters was opened for testing and showed excellent flow characteristics through a vertical well, reaching a stable production rate of 510 thousand cubic meters (18.01 million cubic feet) of natural gas per day, with a choke of 32/64" and a well head upstream pressure of 3,050 psi. A choke of 40/64" was attempted and resulted in a  production rate of over 700 thousand cubic meters (24.72 million cubic feet) of natural gas per day; however, this level exceeded the operational well tester capacity and after 10 minutes the choke was changed out for 32/64" for the duration of the test. The calculated AOF for this test was 7 million cubic meters (247.21 million cubic feet) of natural gas per day.The tested prospect, located southwestern of the Juruá Field, is part of a geological structure covering an area of around 56 km2, and which is estimated to hold between 10 and 32 billion cubic meters (0.35 to 1.13 Tcf) of recoverable gas."This is one of the best gas wells ever drilled and tested onshore Brazil, considering the thickness and quality of the reservoir as well as the DST flow results. It not only confirms the gas trend to the south and east of the Juruá Field, showing integration with the natural gas findings of wells 1-HRT-5-AM, 1-HRT-8-AM and 1-HRT-2-AM, but it opens a new exploration frontier to the southwest. HRT believes that this structure has a potential flow rate of up to 3.0 million cubic meters (105 million cubic feet) of natural gas per day, when it reaches its development phase. This discovery plays a key role in the assessment of the gas potential of the Solimões Basin", mentioned Milton Franke, Chief Executive Officer of HRT O&G."This result demonstrates that the Solimões Basin holds one of the largest potentials for gas among Brazilian basins and will allow to accelerate the gas monetization plan in the area", said Marcio Rocha Mello, CEO of HRT and Chairman of the Board.The well 1-HRT-9-AM, jointly with previous discoveries made in this sub-region of the Basin, will be part of an evaluation plan to be submitted to ANP in due course.HRT is the operator of 21 blocks in the Solimões Basin, which it is exploring in co-operation with TNK-Brasil, a subsidiary of TNK-BP, a Russian joint venture between BP and the consortium AAR.For further information, please contact HRT`s Investor Relations Department.Sedar Profile # 00031536Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.About HRTHRT Participações holds one of the largest independent oil and gas exploration and production companies in Brazil.
