Located about 115 km (71 miles) offshore Brazil’s Rio de Janiero state, the Poraquê Alto well was drilled to a final depth of 4,568 m (14,987 ft) with a water depth of 1,107 m (3,632 ft), Petrobras said in a news release.

Drilled to a total depth of 1,676 m (5,500 ft), the Rio Grande Oeste 1 exploration well identified 15 potential reservoir sands with a potential net pay of 122 m (400 ft), GeoPark said in an Aug. 10 news release.

Drilled to a total depth of 2,837 m (9,308 ft), the well hit a 24-m (79-ft) gross hydrocarbon column across three intervals, about 11 m (36 ft) net of condensate and gas in the primary objective and about 4 m (13 ft) net of oil in the deeper secondary objective, the company said.

Describing the discovery as small, Statoil said the Gemini North well—drilled by the Songa Enabler—also proved oil.

The company said its Marauder-1 well, located in PEL 104, encountered good oil shows within Birkhead sands with evaluation of logs indicating net pay of up to 8.6 m within a 17.5 m gross oil column.

The latest discovery brings the estimated gross recoverable resources for the Stabroek Block to between 2.25 Bboe and 2.75 Bboe, the company said.

The find at the Blaamann well is estimated to hold up to 3 billion standard cubic meters of recoverable gas. No oil was found.

Operators are finding oil in Mexico’s shallow waters as they look to grow reserves.

Located in a water depth of about 2,175 m (7,136 ft)  in the Sangomar Deep Offshore Block, the well was drilled by the Stena DrillMAX drillship about 30 km (19 miles) southwest of the FAN-1 exploration well.

AWE Ltd. has confirmed the extension of the Waitsia Field in Australia with the Waitsia-3 well encountering natural gas shows in the Kingia and High Cliff sandstone reservoirs, the company said in a July 4 news release.

Statoil said the Kayak well, which was drilled by the Songa Enabler in the Johan Castberg license, made a discovery totaling between an estimated 25 and 50 million barrels of recoverable oil equivalents.

Rosneft and its partners plan to invest $8.4 billion in developing Russia’s offshore energy industry in the next five years, part of a drive to boost output from new areas.
