The Poço Verde 4 well hit a new oil accumulation in the Poço Verde area in the ultradeepwater Sergipe-Alagoas Basin offshore Brazil, Petrobras said June 1. The well is in the BM-SEAL-4 concession.

The well, formally known as Well 3 SES 189, is 23.5 km from the discovery well in 2.479 m of water. Poço Verde ran 5.350 m deep.

The area’s light oil reservoirs are 85 m thick with good porosity and permeability.

This well was the third drilled in the Poço Verde area, which was discovered in July 2012. Poço Verde is part of the exploratory project in the basin. There are five other evaluation plans, Petrobras said.

Petrobras operates the consortium with 75% interest. Partner ONGC, which has 25% interest, will evaluate the results and confirm reservoir conditions and production potential through a test.

The discovery evaluation plan will carry on as approved by the National Agency of Petroleum, Natural Gas and Biofuels.
