Depositional and Diagenetic Evolution of Cretaceous Oncolitic Packstone Reservoirs, Macaé Formation, Campos Basin, Offshore Brazil
The Campos Basin is located approximately 120 miles (200 km) northeast of Rio de Janeiro (Fig. 29-1) and covers an area of about 12,000 square miles (30,000 km2) extending from a small onshore portion to the 660 foot (200-m) isobath, between 21° and 24° south latitude. The Garoupa and Pampo fields (Fig. 29-2) produce from structures in the Macaé Formation, an entirely offshore carbonate sequence which occurs in the central and eastern part of the Campos Basin.
