We are aware of a discrepancy between the seismic data and the shotpoint navigation. WesternGeco has reviewed their digital database, and have concluded that they cannot provide navigation. We are hopeful that we can obtain the navigation from MMS, but have not been able yet to locate it yet. Obviously this would be a valuable survey if the navigation were available. We will continue our efforts to acquire it.
