Brazilian major Petrobras (NYSE:PBR) has temporarily stopped production on the Extended Well Test of the Guara field in the deepwaters of the Santos Basin offshore Brazil.

The production in that area is performed through a dynamic positioning platform called Dynamic Producer. The platform had been under maintenance since last Sunday, with the well shut and all the safety conditions in compliance. 

Yesterday, however, the pipeline that connects the platform to the well was disrupted. There was no oil leak into the sea, since the well was shut and, therefore, there was no oil and gas in the pipeline.

The appropriate authorities have been notified. The well remains shut, and the causes of the pipeline rupture are already being investigated.

After this assessment and with the production system back in order, the necessary steps to restart this extended well test will be taken. 

Petrobras began the EWT of the Guara field on Dec. 25, 2010, and the test is scheduled to last five months.

The Guará area is located in block BM-S-9, about 300 kilometers off the coast of São Paulo state. Petrobras operates the area in partnership with BG Group and Repsol. Recoverable oil and gas volumes in Guará are estimated at 1.1 and 2 billion boe of high quality, at about 30 degree API gravity.


Following the EWT, a pilot project will take place at Guara field, with wells being conneceted to the FPSO Cidade de São Paulo. Production is expect to start by 2013 and is estimated at 120,000 barrels of oil, and five million cubic meters of gas per day.


The Guará EWT will provide Petrobras and its partners with deeper knowledge of the area and its behavior, thereby helping to develop a definitive plan for the region and for the Santos Basin pre-salt layer.
