All of the sites are located within a 3-D seismic reflection survey area, and three of these sites are reoccupations of previously cored holes. The stratigraphy of the other two LWD sites correlates to reflectors determined from the 3-D seismic survey. Comparison of the density profiles between sites penetrating the incoming sedimentary sequence and equivalent strata thrust beneath the accretionary prism quantifies the magnitude of consolidation due to loading by the prism. The high quality of the LWD data coupled with information from the boreholes and seismic data calibrate the logs for recognition of geologic features.
Thrust faults are evident as repeated log signatures, often as density inversions.
Known sediment compositions allow inversion of log signatures to specify sediment types in uncored areas.
