OREANDA-NEWS. September 22, 2011. HRT Participacoes em Petroleo S.A. (the “Company” or “HRT”) (BM&FBOVESPA: HRTP3, TSX-V: HRP) announces that in furtherance to its business plan, HRT signed, on September 15, 2011, the contract with the Joint Venture Andrews Technologies, Inc. and Sichuan Honghua Petroleum Equipment Ltd. (“ATI-HH”) for the acquisition of four heli-transportable drilling rigs for the exploratory campaign in the Solimoes Sedimentary Basin.

The bidding process for the hiring of the drilling rigs was published on June 15 of this year and involved large world corporations. Based on the technical proposals and commercial bids submitted, HRT analyzed them, adopting the best price and technology criteria, thus selecting the ATI-HH company, which holds the know-how and technology for use of heli-transportable equipment, allowing the rigs to be assembled/disassembled in modules, in order to be transported by helicopters to operate in areas of difficult access, like the Amazon region.

The rigs have the capacity to drill up to a depth of four thousand meters. The first two rigs should arrive in the Shanghai Port, in China, in February, and the remaining ones, in March of 2012. After this delivery, the equipment is expected to arrive in Manaus within approximately two months, ready to be transported to the Support Base, and later, to the drilling site.
