TRIDENT 3D

Enhanced structural imaging, improved signal : noise and an optimized response at prospective levels
Website Map for Survey TRIDENT
The dataset covers part of the NW-SE-trending Anglo-Dutch Basin in the Southern North Sea. This area is an extremely rich and mature gas province, with several key fields (e.g., Carrack, Cutter, Grove). This survey aims to facilitate field level interpretation and near-field exploration.
The Southern North Sea developed through a complex history of basinal subsidence, punctuated by episodes of uplift and erosion. The prospectivity relies on the Carboniferous (reservoir and source). Deformed Zechstein salt forms the top seal to the main petroleum system and creates Triassic traps.
Major improvements include enhanced structural imaging, improved signal to noise and an optimized response at the prospective deeper Carboniferous and Rotliegendes sediments.
