The No. 2 creditor after bondholders is OSX Brasil SA (>> OSX BRASIL SA), the Batista-controlled shipyard and ship-leasing company that built three offshore oil production platforms for OGX. OSX is owed at least 2.45 billion reais ($1.1 billion) or about 21 percent of the oil company's obligations.

The next largest creditor is Schlumberger NV (>> Schlumberger Limited.), the world's largest oilfield service company, which is owed at least 214.7 million reais or 1.9 percent of obligations, according to Reuters analysis of the list.

The 8.17 billion reais ($3.6 billion) owed to holders of OGX's bonds, which expire in 2018 and 2022, accounts for about 72 percent of the company's consolidated obligations.

The creditor list was part of the bankruptcy petition filed on October 30 in a Rio de Janeiro court by OGX Petróleo e Gas SA (>> OGX Petroleo e Gas Participacoes SA), as the company is formally known.

OGX's bankruptcy filing, the latest major development in one of the biggest corporate meltdowns in recent history, stemmed from the company's inability to meet ambitious production targets set by Batista, who hailed OGX as the flagship of his once high-flying energy, commodities and logistics empire.

With little revenue and a share price that plunged more than 98 percent in the last 16 months, OGX ran out of cash to pay debt, suppliers and other companies in his EBX group. Some EBX companies, including a port operator and a shipbuilder, depended on each other for revenue and the value of their shares also plummeted during the selloff.

Batista, who was once worth about $30 billion and was the world's seventh-richest man, in the process saw his fortune dry up, leaving him without the assets or credit necessary to keep financing his companies. He was unable, for instance, to fulfill a promise to bolster OGX by buying as much as $1 billion worth of new stock.

Now, OGX hopes the bankruptcy can help it restructure.

The top-five creditors after the bondholders is rounded out by Houston-based drill-rig operator Diamond Offshore Inc (>> Diamond Offshore Drilling Inc), owed 91.4 million reais; London-based drill-rig operator Ensco Plc (>> ENSCO PLC), owed 63.9 million reais; and Fairfield, Connecticut-based General Electric Co (>> General Electric Company), owed 54.1 million reais.

Together, Schlumberger, Diamond, Ensco and GE hold about 4 percent of OGX's obligations.

The list contains nearly 250 specific creditors, including major companies such as Brazilian state-run oil company Petroleo Brasileiro SA (>> Petroleo Brasileiro Petrobras SA), also known as Petrobras, which is owed 40.9 million reais.

Thomson Reuters Corp (>> Thomson Reuters Corporation), the parent company of Reuters News, is owed 26,189 reais.

Smaller creditors include a downtown Rio de Janeiro deli, several taxi cooperatives and FedEx Corp. (>> FedEx Corporation) each being owed several hundred or several thousand reais. OGX's smallest creditor, Rosario Placas e Carimbos, a sign and rubber-stamp company, is owed 0.50 reais, or about 22 U.S. cents.
