Petrobras on Thursday announced its proved reserves of oil, condensate and natural gas in 2009 according to the Society of Petroleum Engineers SPE and Security and Exchange Commission -- SEC criteria.

Petrobras' Proved Reserves in 2009 (Brazil and International)

As per as ANP/SPE criteria:

On December 31st, 2009 Petrobras Proved Reserves of oil, condensate and natural gas amounted to 14.865 billion barrels of oil equivalent (boe), a decrease of 1.5% in relation to last year figures.

According to the SPE Criteria, 652 million boe were incorporated into Proved Reserves in 2009 and 872 million boe were produced, resulting in a decrease of 220 million boe in relation to 2008 proved reserves (15.085 billion boe). This decrease is mainly due to Bolivian reserves exclusion from the total amount.

According to SPE criteria, the Reserve Replacement Index (RRI) in 2009 was 75% and the Reserve/Production (R/P) ratio was 17 years.

According to SEC criteria:

On December 31st, 2009, Proved Reserves were 12.143 billion boe, representing an increase of 9% in relation to 2008.

According to SEC criteria, 1.824 million boe were incorporated into Proved Reserves during 2009 and 872 million boe were produced, resulting in an increase of 952 million boe in relation to 2008 reserves (11.191 billion boe).

According to the SEC criteria the RRI in 2009 was of 209% and the Petrobras' Reserve/Production (R/P) ratio was 14 years.

Petrobras Proved Reserves in Brazil

According to ANP/SPE criteria:

On December 31st, 2009 the Proved Reserves of oil, condensate and natural gas in the fields under concession of Petrobras in Brazil amounted to 14.169 billion boe, representing an increase of 0.5% in relation to 2008.

During 2009, 861 million boe were incorporated into Proved Reserves, with production over the same period amounting to 785 million boe.

For each barrel of oil equivalent produced in 2009, 1.10 boe were incorporated into Proved Reserves, resulting in a Reserve Replacement Index (RRI) of 110%. According to SPE criteria, Petrobras Reserve/Production (R/P) ratio in Brazil was 18 years.

The highlights in 2009, in terms of Proved Reserves incorporation, were:

 

  • Discoveries in exploratory blocks and new accumulations Discoveries in Andorinha, Irauna and Sanhacu in Rio Grande do Norte and Ceara, Exploration & Production Business Unity - UN-RNCE; New accumulations in Fazenda Belem in Bahia Exploration & Production Business Unity UN-BA; Marimba in Campos Basin Unity UN-BC; Urugua in Santos Basin Unity UN-BS; Sao Mateus in Espirito Santo Basin UN-ES; Marlim Leste and Marlim Sul in Rio de Janeiro Business Unity UN-RIO and Canto do Amaro and Serra do Mel in Rio Grande do Norte and Ceara Exploration & Production Business Unity - UN-RNCE.
  • Incorporations from existing fields in 2009 via secondary recovery projects mainly in Roncador, Marlim Sul and Marlim Leste fields in Rio de Janeiro Business Unity UN-RIO; Papa-Terra and Xerelete in Campos Basin Unity UN-BC; Baleia Azul and Baleia Franca in Espirito Santo Unity UN-ES.
  • The pre-salt discoveries from the Espirito Santo Basin are contributing with 182 million barrels of oil equivalent in proved reserves. The pre-salt discoveries from the Santos Basin are still under evaluation, none of them were incorporated.
  • According to SEC criteria:

    According to SEC criteria, 2.074 billion boe were incorporated into Proved Reserves during 2009, equivalent to 2.6 times the 785 million boe produced.

    On December 31, 2009, Proved Reserves in Brazil increased 13% in relation to 2008 and the Reserve Replacement Index (RRI) was 264%. Petrobras' Reserve/Production (R/P) ratio in Brazil was 15 years.

    In accordance with 2009 SEC new criteria for reserves disclosure, the oil price taken in account isn't the one of December 31st anymore, but the average oil price of the year. During 2009, Brent average price was US$ 60.2/bbl against US$ 36.55/bbl on 31/12/2008. This price increase had a positive effect of 1.074 billion boe in the incorporation of Proved Reserves.

    The main differences between SEC and ANP/SPE criteria, are due to the different assumptions used (oil price, concession term and gas reserves) and the non-booking of projects in the initial stage of production development in the Company accounts.

    International Proved Reserves

    According to SPE criteria:

    On December 31st, 2009 the Proved Reserves of oil, condensate and natural gas abroad amounted to 0.696 billion barrels of oil equivalent (boe), representing a decrease of 30% in relation to 2008.

    This reduction is mainly a result of the produced volume in 2009 and of the fact that the Bolivian reserves was not considered as proved reserved anymore due to new Bolivian Constitution which prohibits accountancy and register of reserves of oil and natural gas by public companies. This reduction was partially offset by the incorporation of reserves from Nigeria and USA.

    According to the SPE criteria the Reserve Replacement Index RRI in 2009 was of -240% and the international Petrobras' Reserve/Production (R/P) ratio was 8 years.

    SEC criteria:

    On December 31st, 2009 the Proved Reserves of oil, condensate and natural gas in the international fields under concession to Petrobras amounted to 580 million barrels of oil equivalent (boe), representing a decrease of 37% in relation to 2008 (917 million boe).

    This reduction is mainly a result of the produced volume in 2009 and of the fact that the Bolivian reserves was not considered as proved reserved anymore and was partially offset by the incorporation of reserves from Nigeria and USA.

    According to the SEC criteria the Reserve Replacement Index RRI in 2009 was of -287% and the Reserve/Production (R/P) ratio was 7 years.

    Petrobras clarifies that the hydrocarbon reserve properties belong to their respective National States.
