SHARING PETROBRAS NEWS

T he consortium formed by Petrobras (40%), the Dutch company Shell (20%), the French company Total (20%), and the Chinese companies CNPC (10%) and CNOOC (10%), won the 1st Pre-Salt Bidding Round, carried out on October 21 in

Rio de Janeiro by the National Agency of Oil, Natural Gas, and Biofuels (ANP).The contract will be in the shared production mode, under a production sharing

framework, and establishes a signature bonus of R$ 15 billion to be paid in one payment, with Petrobras’ participation being R$ 6 billion. In the proposal, the consortium offered the Brazilian government 41.65% of the profit oil. The proposal also foresees a minimum percentage of 37% of local content in the exploration phase, 55% in the development stage for systems with first oil until 2021, and 59% for those after 2021.

The Libra block is located in ultradeep water in the Santos Basin pre-salt layer, with an area of 1,547.76 km², and was discovered in 2010. Petrobras believes in the exploratory success of the block, based on the expertise already developed and on the projects implemented in the region, which has currently reached a total production above 330,000 barrels of oil per day.

For us, strategies in the bidding were successful and consolidate our commitment to invest in exploratory areas in Brazil in order to renewal our portfolio, making available volumes of oil and natural gas necessary to sustain the future production curve. In addition, we believe that the integration of expertis and experiences of the partners will bring important contributions to reach efficient results.

Petrobras’ net profit in the first nine months of 2013 was R$ 17.3 billion

Our net profit from January to September was 29% higher than that in 2012 as a consequence of the increase in the

operational result and of the lower foreign exchange impact in our financial result. The 3% higher operational result reflected the earnings with the sale of assets and the lesser decreases in scheduled stoppage wells, which compensated the losses from the price gap. The adjusted Ebitda in the period reached R$ 47.4 billion, 14% higher than that of the same period in 2012.

In the third quarter, our net profit was R$ 3.4 billion, 45% lower than that of the previous period, reflecting the lower operational profit, partially compensated by the better financial result. The operational result was 51% lower, impacted by the increase in the import of oil products and by the higher price gap of these products, a consequence of the currency depreciation together with the increase in the international oil price.

The production of oil and natural gas totaled an average of 2.5 million boe/day during the nine-month period, 2% lower than that of the same period in 2012, in consequence of the natural decline of the fields, the greater number of scheduled stoppages in 2013, and the sale of assets abroad.

On the other hand, the production of oil products totaled 2.1 million boe/day, 7% higher than that in the same period in 2012, with monthly records of processing in July and in diesel and gasoline production in August. The demand for diesel in the third quarter was record.

In the quarter, we maintained the success of the improvement in operational efficiency through the Efficiency Improvement Program (Proef)): an increase of 65,000 barrels/day. The Divestments Program (Prodesin) evolved with the announcement of operations in Brazil and abroad, totaling US$ 4.8 billion in the year-to-date, and the Operating Expenses Optimization Program (Procop) had results above the predicted amount, with the realization of R$ 4.8 billion, 122% of the annual target.

The investments from January to September totaled R$ 69.3 billion, with 55% in Exploration and Production.

We are investing in the Northeast region, in two strategic pro-jects, to increase the production of oil and to ensure the flow

of oil produced in the onshore fields in Rio Grande do Norte state. One of the projects is for the expansion of the system of water

injection in the Canto do Amaro field in Mossoró (RN) - one of the largest in the country. The other project will facilitate the flow of the production, interconnecting this field to a processing unit in Guamaré through an oil pipeline 100 km long. This operation is scheduled to begin in August 2014.

Platform P-55 will begin operation in December—

On October 6, platform P-55 (photo to the side) left the Rio Grande Shipyard 1 (ERG-1), in Rio Grande do Sul, in route to the Roncador field in the Campos Basin. It is one

of the units that will begin activities in 2013, contributing to the sustained increase of oil production in the coming years.

With 52,000 tons, an area of 10,000 m², and a height of 43 meters, it is the largest semi-submersible platform built in Bra-zil and one of the largest in the world. It generated 5,000 direct and 15,000 indirect jobs during the construction, with 79% of local content.

The hull was prepared at the Atlântico Sul Shipyard in Pernam-buco, from where it was taken to the ERG-1, where the deck ins-tallations were done. The operation which joined the deck and the hull, called deckmating, was a challenge, considering the weight of the structure (17,000 tons) and the height to which it was raised (47.2 meters).

The platform has the capacity to produce 180,000 barrels of oil and 4 million m³ of gas per day and will stay anchored at a depth of 1,800 meters, connected to 17 wells. The unit will be operated by a crew of 100 people.

Conclusion of the third well in Jupiter

T he drilling of the well Bracuhy, located in block BM-S-24 in the pre-salt region in the Santos Basin,

has been concluded. This is the third well drilled in the area of Jupiter, which proved the existence of oil, gas, e condensate, beginning at a depth of 5,322 meters.

In August, we put into operation one more Safety and Maintenance Unit (UMS) to prolong the useful life of the production platforms,

ensuring the integrity of their marine installations, the safety of the work force, and the increase of operational efficiency.

The Carapebus City UMS will operate together with the Campos Basin units for the next five years. It is equipped with a dynamic positioning system and can be connected to any type of platform. The total length of the vessel is 180 meters and it can house 533 professionals.

SPECIAL

P etrobras completed 60 years of existence on October 3. In a rhythm of growth, our target is to double the current oil production by 2020, reaching 4.2 million barrels of oil/

day. New platforms will start operating and others are under construction, in addition to new refineries. When it was created in 1953, the company produced 2,700 barrels of oil/day, had 170 million barrels of oil in reserves, and one refinery. Today, in Brazil, 2 million barrels of oil are produced daily, and there are 15.7 billion barrels of oil equivalent in proven reserves and 12 refineries.

“People are what inspire us” was the theme of the advertising campaign launched to commemorate the 60 years. The objective was to inspire the public, which is also our source of inspiration. The campaign had ads on TV and radios, and in newspapers and magazines, which showed recent achievements and the goals for the coming years. Virtual environments were also created (on Facebook and Instagram), which showed contents that could be shared, such as photos and texts. In the month of our anniversary, our Facebook page surpassed the mark of one million fans.

In addition, the Neptune Mission was launched, which took the Brazilian flag and a capsule with messages from Brazilians in a submarine to the pre-salt region, located at a depth of more than 2,000 meters and 300 kilometers from the coast. More than 55,000 people sent messages. Ten years from now, these messages will be retrieved.

The Brazilian National Congress also paid tribute, in a formal session. The presidents of the Senate and the Chamber of Deputies, Petrobras’ CEO, ministers of state, and other authorities participated. The speeches stressed the trajectory of the company and its contribution to the country’s development. A commemorative stamp was also launched, in partnership with the Post Office.
