Oleo e Gas Participacoes SA, the bankrupt oil company controlled by Brazilian tycoon Eike Batista, received a $44 million offer for five oil exploration and production blocks in Colombia, the company said on Friday. The offer involves $30 million in cash and the assumption of $14 million in future exploration obligations in Colombia, Oleo e Gas said in a statement. It did not give the name of the investor or company making the offer. Oleo e Gas was formerly known as OGX Petroleo e Gas Participacoes SA. If approved by a bankruptcy judge, creditors and Oleo e Gas shareholders, the sale will help the Rio de Janeiro-based company pay for leases on offshore oil production ships and its share of investments in output in Brazil, the company said.
