The Idan Ofer-controlled company said the US oil major has signed a firm contract extension for the Pacific Bora.

The two-year deal increases the US-listed drillship owner and operator’s backlog by around $439m, it said in a statement.

Earlier this month the company reported a second quarter profit that was more than double that of a year ago.

Net income was $49.9m, while revenue for the three month period rose 47.5%
