Batista created OSX, which had to scale back efforts to construct the largest shipyard in the Southern Hemisphere, to build and lease oil production and service vessels to OGX.
A renowned dealmaker who once boasted he was on track to become the world's richest man, 56-year-old Batista has seen his personal fortune reduced by over $30 billion in the last 18 months as investors punished the share price of his listed companies.
The downward spiral forced Batista to start breaking up his Grupo EBX conglomerate, which also included a port operator, mining and energy interests, and an entertainment company.
Batista's rapid decline has become a symbol of Brazil's own economic troubles. After a decade-long boom in which investors poured cash into Brazil and Batista's enterprises, Latin America's largest economy has been in a rut for nearly three years, frustrating predictions that the country was poised to join the ranks of developed nations.
OGX's decision to seek protection from creditors came as no surprise. After missing a $44.5 million interest payment owed to bondholders on Oct. 1, OGX scrambled to restructure its debt before the end of a 30-day grace period or be declared in default on $3.6 billion in bonds.
The process was rocky from the outset, and OGX called off the talks with creditors on Tuesday, leaving a bankruptcy filing as the only viable option to buy more time in its quest to save the company.
