NON-SEC COMPLIANT OIL AND GAS RESERVES:
CAUTIONARY STATEMENT FOR US INVESTORS
We present certain data in this presentation, such as oil and gas
resources, that we are not permitted to present in documents filed with

Oil Production in the Pre-Salt
Daily Record of 546 th. bpd on July/13 with 25 wells
Th. bpd
High productivity of Pre-salt wells contributed to lower lifting costs (LF) for these projects.
Lula field has a lifting cost of US$ 9/boe (2013), whereas Petrobras LF was US$ 14.76/boe.
Sequential records in Pre-Salt production:
 February 18th: connection of the 1st buoy (BSR1) to FPSO Cid. São Paulo, with 36 th. Bpd (best well in the country);
 March 17th: P-58 1st oil;
 April 3rd: interconnection of the 2nd well to BSR1, with 35 th. Bpd;
 April 15th: Start-up of gas exports from FPSO Cid. São Paulo;
 May 9th: interconnection of the 1st well to BSR2 (FPSO Cid. Paraty), with 31 th. bpd;
 May 9th: Installation of BSR4 finalized, the last of the 4 Buoyancy Supported Risers;
 June 25th: Start-up of gas exports from FPSO-Cid. Paraty;
 June 28th: Start-up of gas exports from P-58.

Oil and Natural Gas Production Costs in Brazil
Higher productivity leads to stable lifting cost
2Q14
Cost reduction in Reais when compared to 1Q14, due to the increase in total production (+2.6%), resulting from ramp-up of
new systems (P-58, P-55, P-62 and FPSO São Paulo). Small increase in cost when expressed in US$, due to FX appreciation

New production records in the refining segment
• Excellent efficiency levels: utilization factor of 98% in 2Q14.
• New monthly record of 2,172 th. bpd in June, 21 th. bpd above the previous record achieved in March 2014
Paulínia Refinery – REPLAN
Capacity: 415 th. bpd
The significant increase in the level of output resulted from better performance achieved by the start-up of new quality
and conversion units, as well as the optimization of refining processes and the removal of logistics bottlenecks.

Trade Balance: Oil and Oil Products
2Q14 vs. 1Q14: Higher oil imports lowers gasoline imports
2Q14 vs. 1Q14
 Reduction in oil exports due to export cargos in transit (and therefore not yet recognized) and higher refining throughput.
 Lower product imports as a result of higher gasoline production.
 Higher oil imports during 2Q14, particularly in June, based on market conditions that should favor refining higher
volumes of imported oil. Additionally, REPLAN’s stoppage in 1Q14 distorts basis for comparison.

Projection
In Reais, unit cost stable. Increase of 7% in US$ due to FX appreciation. Cost stability a result of optimizing operational costs
(PROCOP) and from increasing sustainable levels of throughput (PROMEGA).

2Q14 x 1Q14
 Gas supply to the market totaled 96 million m3/day, a 6% growth over 1Q14. Increase in supply led primarily by LNG
imports to meet higher thermoelectric demand.
 Petrobras power generation reached 4.7 GW (4.1 GW in 1Q14), with margin gains, since spot price for energy was
stable (approximately R$ 650/MWh) while unit cost of imported LNG was 8% lower than 2Q14.
