At 38,000 square feet in size, they produced average weekly sales of $564,000 translating to sales per square foot of $777, and generated a contribution margin of approximately 6%.

Last month, Brazilian Petrobras awarded Norway's SeaDrill with contracts for three deepwater rigs worth up to $4.1 billion, with day rates in excess of $600,000.
