Brazil’s state controlled oil company, Petrobras, announces that on Sunday afternoon, April 8, a subsea inspection discovered seepage of oil coming from its Roncador oil field’s seabed in Campos basin.

The inspection was carried out using a Remotely Operate Vehicle (ROV), at the field located approximately 120 km off the coast of from the coast of São Tomé Cape, Rio de Janeiro State, Brazil, near the Chevron operated Frade field where two seeps – one in November, 2011 and the second in early March, 2012, occurred.

According to the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP), the ROV was submerged approximately 500 meters to the East from the Frade field border line, where it collected oil samples which should help with identifying the source of the leak.

So far, no oil slick can be seen on the surface of the sea.

Chevron Throws the Brakes on Current and Future Drilling Offshore Brazil

By gCaptain Staff

SAN RAMON, Calif., November 23, 2011 – Chevron Corporation (NYSE: CVX) today reports that while its subsidiary, Chevron Brasil Upstream Frade Ltda., has not received formal notice from Brazil’s National Petroleum Agency (ANP) suspending its drilling license, the company has voluntarily suspended its current and future drilling operations, offshore Brazil. The voluntary suspension includes the company’s permitted pre-salt wells in the Frade field with the exception of current plug and abandonment activities. The suspension is indefinite. Chevron acknowledges, however, that ANP has posted a notice of suspension to its website.

Chevron’s decision to suspend its drilling operations has no impact on its current production in the Frade field or on other Frade field operations. Production from the Frade field is approximately 79,000 barrels of oil equivalent per day (approximately 36,000 barrels net).

Chevron had previously suspended development drilling in the Frade field on November 9 after it became aware of oil migrating from seep lines in the ocean floor.

Chevron also reports that the volume of oil currently contained in the sheen on the ocean’s surface has been further reduced to about one barrel through cleaning and dispersion methods approved by Brazilian authorities. Chevron was successful in stopping the primary source of the oil sheen ten days ago.

The company reiterated that it adheres to all the rules and regulation of the Government of Brazil and its agencies.

Updated video footage of the seeps on the ocean floor and current photos of the sheen on the ocean’s surface are available on Chevron’s Media Updates page.
