The increasing use by academic institutions of high-resolution swath bathymetry and sea-floor imaging techniques, coupled correlating seismic anomalies from 3D mapping with core and well logging data reveals the depositional geometry and sedimentological characteristics of coarse-grained contourites.

Contourite deposits must present some particular characteristics. Coarse-grained sediments,preserving good petrophysical characteristics, such as porosity, permeability, and lateral and vertical transmissibility of fluids, must form part of the deposit, wich could be a great reservoir.

Fine-grained drifts can locally and regionally develop large and thick accumulations, which have an important seal potential for trapping hydrocarbon. The depth, thickness, extent and properties of these sands are determining.
