High resolution 3-D visualisation of horizon interpretation and Previous HitseismicNext Hit Previous HitattributesNext Hit from large 3-D Previous HitseismicNext Hit surveys in deepwater Nigeria has greatly enhanced the exploration team's ability to quickly recognise prospective segments of sub-regional and prospect specific scale areas. Integrated workstation generated structure, isopach and extracted horizon consistent, interval and windowed Previous HitattributesNext Hit are particularly useful in illustrating the complex structural and stratigraphic prospectivity of deepwater Nigeria.

Large 3-D Previous HitseismicNext Hit volumes acquired over 750 square kilometers can be manipulated within the visualisation system with attribute tracking capability that allows for real time data interrogation and interpretation. As in classical Previous HitseismicNext Hit stratigraphic studies, pattern recognition is fundamental to effective depositional facies interpretation and reservoir model construction. The 3-D perspective enhances the data interpretation through clear representation of relative scale, spatial distribution and magnitude of Previous HitattributesNext Hit.

In deepwater Nigeria, many prospective traps rely on interplay between syndepositional structure and slope turbidite depositional systems. Reservoir systems in many prospects appear to be dominated by unconfined to moderately focused slope feeder channel facies. These units have spatially complex facies architecture with feeder channel axes separated by extensive inter-channel areas. Structural culminations generally have a history of initial compressional folding with late extensional collapse and accommodation faulting. The resulting complex trap configurations often have stacked reservoirs over intervals as thick as 1500 m. Exploration, appraisal and development scenarios in these settings can be optimised by taking full advantage of integrating high resolution 3-D visualisation an Previous HitseismicTop workstation interpretation.
