Petrobras: 'cracked connector caused rupture'
Brazil's Petrobras, said late yesterday, that a cracked connector caused the rupture in an early production riser that forced the company to halt an extended well test at a pre-salt oilfield in March.
Petrobras has agreed to work with the Argentine government on a new investment plan for Argentina, where one of the Brazilian oil giant's drilling permits was cancelled, officials said.
