A basin modeling study of the reprocessed survey has enabled better interpretation of the subsalt intervals and fault units due to enhanced velocity analyses and multiple algorithms. The updated data has pointed to some hydrocarbon plays. As part of the effort, four levels of hydrocarbon plays were observed:
- Post-rift postsalt—Ebro group with biogenic gas expected within clastic turbidite deposits in the Plio-Pleistocene
- Post-rift presalt—San Carlos group with Deltatic/turbidites deposits in the Miocene age
- Synrift—basal tertiary group with Deltatic/canyon sands in the Lower Oligocene
- Proven prerift with carbonate buildups in the Mesozoic
The proven hydrocarbon reservoirs on the western Mediterranean are allocated to the Mesozoic age and represented by Upper Jurassic limestones and Lower Cretaceous shallow marine carbonates (limestones and dolostones). Potential leads of Mesozoic age were mapped on the reprocessed data and clastic Tertiary reservoirs have been justified and mapped.
