RIO DE JANEIRO – OGX Petróleo e Gás has another discovery in the shallow-water southern sector of Brazil’s Campos basin.

The OGX-52 (Tambora) well was drilled by the Ocean Ambassador in the BM-C-41 block, 93 km (58 mi) offshore Rio de Janeiro state in a water depth of roughly 130 m (426 ft).

It encountered a 12-m (39 ft) hydrocarbon column in Santonian sandstone reservoirs with about 5 m (16 ft) of net pay. In addition, a 174-m (571-ft) hydrocarbon column was encountered in Albian carbonates with around 96 m (315 ft) of net pay.

''This new discovery nearby the Waimea accumulation successfully tested Albian calcarenites in a deeper position, completely independent of the prior discovery,'' said Paulo Mendonça, OGX’s general executive officer and exploration officer.

“Also, it is important to note the discovery of oil in sandstone reservoirs of the Santonian age. These discoveries confirm, as we have mentioned, significant potential remaining resources in this important oil province in the southern portion of the Campos basin.''
