The imaging of deep-water turbidite slope-channel systems in Offshore Angola has improved greatly during the past decade through the acquisition of high resolution seismic surveys. Within the Marte Field, located in Block 31 NE, high resolution seismic data provides greater definition of the internal stratigraphy of third-order channel complexes. Fourth-order channel cuts and associated facies, including muddy slumps, within the third-order systems have been mapped in considerable detail. Better definition of the internal depositional architecture reveals a high degree of heterogeneity within the channel systems and offers insights into the fluid dynamics of Marte Field reservoir systems.
