In deepwater exploration the objective is to maximize knowledge of the prospect, determine its viability before committing to drill, and then reduce the technical and economic variables. You'll get the clearest picture of the subsurface—and the most information—by integrating proven, complementary technologies.

Ranking deepwater subsalt prospects is challenging. Although salt and sediment have large contrasts in properties, translating measurements into useful information is difficult. Services that exploit their differences to answer specific parts of the puzzle reduce the unknowns. Seismic and complementary measurements, combined with 3D full-tensor gravity measurements, help identify salt bodies and associate their structures and boundaries with those of sedimentary targets. Combining these measurements constrains models and helps to speed the well-ranking and placement process.
Seismic data acquired from more than one direction are illuminating structures that standard surveys find hard to image, such as carbonate rocks or laminated sands below salt and basalt formations. Multi-, wide-, and rich-azimuth techniques result in better signal/noise ratios and natural attenuation of some multiples. Coil Shooting full-azimuth, single-vessel acquisition geometries take the concept further, recording data from a wide range of directions.
Acquiring high-quality seismic and well data is the starting point for all reservoir simulations. But complementary data conditioning, processing and inversion, and interpretation workflows are critical for obtaining optimal results from subsequent reservoir modeling.
