Oil and natural gas production in 2015

Rio de Janeiro, January 15, 2016 – Petróleo Brasileiro S.A. – Petrobras hereby announces that its average Brazilian oil production in 2015 exceeded the annual target established in the Company’s Business and Management Plan for the first time in 13 years.

The period average of 2.128 million barrels per day (bpd) was 4.6% higher than the previous year and 0.15% up on the 2.125 million bpd envisaged in the business plan.

Pre-salt production averaged 767,000 bpd, 56% more than in 2014 and the Company’s highest ever figure.

Factoring in natural gas output, which grew by 9.8% over the year before, total production reached 2.6 million barrels of oil equivalent (boed) per day, 5.5% more than the 2.46 million boed recorded in 2014.

According to Petrobras’ CEO, Aldemir Bendine, “this result is important as it demonstrates the company’s enormous operating capacity, even in an adverse global scenario for the oil and gas industry, and because it exemplifies the predictability and transparency of its activities before the market.”

Bendine emphasized that “the result reinforces our conviction in the decision to prioritize investments that are effectively capable of generating results, with absolute priority for exploration and production projects.”

The rapid growth of production from the P-58 platform, which operates in the Parque das Baleias complex in the Espírito Santo portion of the Campos Basin, and the FPSO Cidade de Mangaratiba, in the pre-salt area of the Santos Basin, were among the factors chiefly responsible for last year’s output expansion. Further impetus came from the anticipation (from November to July) of the start-up of the FPSO Cidade de Itaguaí, in the Santos Basin.

“We have consolidated our deepwater and ultra deepwater exploration expertise. In 2015, we managed to reconcile technological progress with reduced operating costs, leading to a lifting cost of eight dollars per barrel in the pre-salt fields in the third quarter,” explained Solange Guedes, the company’s Exploration and Production Officer.

The satisfactory performance on other production fronts also played a decisive role in achieving the 2015 target, exemplified by annual output from the Marlim field in the Campos Basin, which exceeded 200,000 bpd, and the Campo de Roncador field, which  reached its highest ever volume of more than 400,000 bpd.

Oil production abroad averaged 99,000 bpd in 2015, 14.4% down on the 116,000 bpd posted in 2014, primarily due to the conclusion of the asset sales in Colombia and Peru in 2014 and in Argentina in March 2015. The impact of these operations was partially offset by the start-up of production in the Saint Malo and Lucius fields in the United States in December 2014 and January 2015, respectively.

Gas production abroad averaged 15.4 million m³/d, 3.1% less than the 15.9 million m³/d recorded in the previous year. In 2015, the transfer of the units in Peru and Argentina was concluded, production from the Hadrian South field in the United States began in March, and two new wells started up in Rio Neuquén in Argentina, giving 190,000 boed, 9.4% down on the previous year’s 209,000 boed.

Consolidating domestic and foreign output, the company also achieved two new records: total oil production came to 2.23 million bpd, 3.6% up on 2014 (2.15 million bpd), while total oil and gas output reached 2.79 million boed, 4.3 more than the year before (2.67 million boed).

Oil and gas production in December

The company’s oil production in Brazil averaged 2.18 million bpd in December 2015, 5.2% more than in the previous month. Gas output grew by 6.9% in the same period, reaching 76.7 million m³/day. Combined oil and gas production stood at 2.66 million boed, a 5.5% improvement over the 2.52 million boed recorded in November.

Petrobras’ pre-salt oil output reached a new monthly record of 874,000 bpd, 6.6% up on the 820,000 bpd in the previous month.

Pre-salt oil and gas production remained above 1 million boed and was also a new monthly record, reaching 1.090 million boed, 6.6% more than in November (1.023 million boed).

Oil production abroad came to 96,000 bpd in December, in line with the previous month’s figure.

Gas output abroad averaged 16.2 million m³/d, 1.4% more than the 16.0 million m³/d recorded in November, mainly due to increased production in Punta Rosada, in the Rio Neuquén field in Argentina.

As a result, total oil and gas output amounted to 192,000 boed in December, 1.0% more than the previous month’s total of 190,000 boed.
