Petroleo Brasileiro SA (Petrobras) has confirmed the continuation of the light oil accumulation in turbidite sandstone in the Muriu area of the ultradeepwater Sergipe basin.

Petroleo Brasileiro SA (Petrobras) has confirmed the continuation of the light oil accumulation in turbidite sandstone in the Muriu area of the ultradeepwater Sergipe basin.

Well 9-SES-187A reached the total depth of 5,521 m in 2,533 m of water, encountering a 56-m thick reservoir that presents good permeability and porosity features. Oil was of 38-40º gravity.

The well is being completed, and Petrobras says an injectivity test will follow to assess the reservoir’s productivity.

The well is 88 km offshore the city of Aracaju and 2.8 km from the discovery well (OGJ Online, Dec. 5, 2012), part of concession area BM-SEAL-10, Blocks SEAL-M-347 and SEAL-M-424.

The company in August confirmed the presence of 40-m thick reservoirs with good permeability and porosity conditions in Moita Bonita of BM-SEAL-10 (OGJ Online, Aug. 22, 2014).

The accumulation is part of the Sergipe-Alagoas basin deepwater exploration project in Petrobras´ business and management plan for 2014-18.

Petrobras, which holds 100% interest in concession BM-SEAL-10, will proceed with the discovery evaluation plan as approved by Brazil’s Petroleum, Natural Gas, and Biofuels Agency.
