Adele I&II PSDM 3D

2 892 sq km of PSDM reprocessing from field tape utilizing modern reprocessing workflows
Website Map for Survey Adele MC3D
The Adele Trend 3D surveys were selected for PSDM reprocessing from field tape with high graded areas of interest selected for subset reprocessing. Modern reprocessing workflows were employed for greater imaging clarity.
The major prospective fairways in this area lie within the deltaic and marginal marine Lower-Middle Jurassic Plover Formation, and the overlying marine Cretaceous succession.
Reprocessed 3D seismic data to better understand structural complexity of the survey area.
