"Strong Q4 MultiClient late sales revenues offset the weak utilization and productivity for marine contract work in the quarter. Late sales revenues in 2011 were by far the best in PGS' history. Europe, Middle East, and North and South America all delivered strong MultiClient revenues. West Africa will be an important region for us in 2012 as we have commenced a large MultiClient project covering five pre-salt blocks offshore Angola, further expanding our geographical footprint. Our focused MultiClient organization continues to deliver growth and improved results and will over time drive enhanced performance for the Company through the cycle.
