Garoupa Project: an up-to-date of some aspects of the geological interpretation

Abstract

The Garoupa Field produces petroleum solely from Macaé Formation calcarenites and calcirrudites and ranks fourth among Campos Basin fie/ds producing in this reservoir. The evolution of the Garoupa Field's main fault, which coincides with the evolution of the field itself, and the demarcation of the reservoir are discussed. Located on the eastern edge of the field, the Garoupa Fault covers three periods of activitv: from the Late Albian to the Maastrichtian; during the Oligocene (basal and median portion of the corresponding section), and from the Earty to the Middle Miocene. Of the seven production zones, zone X, at the top, pinches out in ail directions and suffers no lateral inflow of water. Zones I and II pinch out to the east and west of the field wifh an active edge aquifer from the NNE and SSW. The same probably holds true for zones III, IV, V and VI.
