Resumen del autor, extraído del artículo. Campos Basin exploration began in 1968, and the first commercial discovery, Garoupa, was hit in 1974. However production activity actually began in August 1977, at the second-discovered Enchova field, in 120m Water Depth (WD). There, a new concept, for Petrobras, was introduced, the Early Production System (EPS). After the installation of the first EPS in Enchova, several others were installed, relocated and demobilized. In 1985, the first deepwater production system in Campos Basin was installed in Marimbá Field, in WD ranging from 350 to 650m. The challenges of deepwaters (400m<WD<1,000m) and ultra-deepwaters (WD>1,000m) in Brazil had to be faced once their overcoming were the only alternative to reach production levels compatible to the Company needs as well as to attend the required fields development pace. To achieve the technological level that allowed Petrobras to develop the deep and ultra-deep fields, a long path has been tracked. This paper describes the main driver forces to exploit deep and ultra-deepwaters fields and the experience that Petrobras has acquired along more than 15 years of deepwater operations; it also shows its main current and planned deepwater programs as well as the next technological steps to be taken to cost-effectively produce in depths down to 3,000m: multilateral, extended reach and design wells, artificial lift, mitigation of hydrate and wax deposition in subsea pipelines, new subsea equipment, development of new risers systems and stationary production units with new mooring systems are some of the key technological issues that are addressed. v. 2, p. 285 CONGTP Formigli, J.M. 9628 Assayag, M.I. 9629 Assayag, S. 9630 Petrobras 547 World Petroleum Congress (16th. : 2000 jun. 11-15 : Calgary, Alberta, Canada) 34 Assayag, M.I. 9629 Assayag, S. 9630 Petrobras 547 Formigli, J.M. 9628 133473 133473 0 0 0 0 204392 BAAB BAAB CD W938 1 0013960 2026-03-04 200005936 0 CD W938 1 0013960 200005936 2026-03-04 14:03:17 2026-03-04 ARCHIVO
