* OGX finds signs of hydrocarbons in Campos basin
* Company recently raised estimates for potential finds
SAO PAULO, Brazil, July 20 (Reuters) - Brazilian oil and gas company OGX Petroleo e Gas Participacoes OGXP3.SA said Tuesday it found signs of hydrocarbons in well 1-OGX-15-RJS in the southern part of the offshore Campos basin.
The new signs of hydrocarbons add to previous finds on wells OGX-2 and OGX-6 in the same area, the company said in a securities filing. The well, which is located in the bloc BM-C-41, is about 78 kilometers (49 miles) off the coast of Brazil’s Rio de Janeiro state — the nation’s largest oil producing region.
OGX, which is controlled by Brazilian billionaire Eike Batista, last week raised its estimates for potential oil discoveries in the offshore Campos basin.
OGX rose 1.5 percent on Monday to 17.97 reais. The stock has risen 4.7 percent this year, compared with a decline of about 8 percent in Brazil's main stock index Bovespa .BVSP. (Reporting by James Matthews and Guillermo Parra-Bernal; Editing by John Picinich)
