Description
The Albacora/Roncador HD3D is a 4D baseline survey designed to repeatedly illuminate the produced and unswept areas of the reservoirs to extend the fields’ production life.
The Albacora turbidite reservoir is producing oil from tertiary sandstones in the Miocene, Oligocene and Eocene intervals.
