Petrobras: En 2013 crecieron sus reservas probadas de crudo

Las reservas probadas de crudo de la petrolera brasileña subieron un 0,8 % en 2013 y llegaron a una cifra de 16.565 millones de barriles de óleo equivalente, informó la empresa estatal.

Reservas probadas de crudo de Petrobras crecen un 1,9 pct en 2013

La petrolera estatal brasileña Petrobras dijo el martes que sus reservas probadas crecieron un 1,9 por ciento en el 2013 debido a que la venta de activos y el descenso natural de las áreas más antiguas limitaron el impacto de las adiciones de reservas de nuevos campos en Brasil.

Petrobras tenía 13.100 millones de barriles de crudo y gas natural equivalente probados a fines del 2013, comparados con los 12.900 millones de barriles del año previo, dijo la firma con sede en Río de Janeiro en un comunicado.

La cifra se basa en los criterios de contabilidad de crudo y gas natural de la Comisión de Valores de Estados Unidos (SEC). Las reservas equivalen a cerca de 18 años de la actual producción de Petroleo Brasileiro SA.

Las reservas de Petrobras han crecido a un ritmo lento en los últimos años, a pesar de más de una década de aumentos en el gasto y de un plan para invertir 237.000 millones de dólares hasta fines del 2017, la mayor parte de ellos en nuevas tareas de exploración y producción de crudo.

El programa de inversión corporativo es el más grande del mundo y ha destinado un promedio de 47.400 millones de dólares en gastos al año.

"Los números son otros en una serie de decepcionantes anuncios de reserva", dijo Cleveland Jones, profesor de geología en el Instituto Brasileño del Petróleo en la Universidad del estado de Río de Janeiro. "Al avanzar, sin embargo, posiblemente veamos algunos mejores resultados", agregó.

El ex presidente ejecutivo de Petrobras Jose Sergio Gabrielli, quien renunció a su empleo en el 2011 y respaldó a la actual presidenta ejecutivo Maria das Graças Foster, había predicho que la compañía tendría cerca de 30.000 millones de barriles de reservas para esta fecha gracias a los gigantescos pozos en altamar al sur de Río de Janeiro.

Bajo criterios menos estrictos de la Sociedad de Ingenieros Petroleros (SPE), las reservas probadas de crecieron un 0,8 por ciento a 16.500 millones de barriles de crudo y gas natural equivalente en el 2013.

Los criterios de reservas demostradas de la SEC son más estrictos que los de la SPE respecto a la capacidad de la compañía de producir el petróleo que descubre de manera rentable.

Petrobras' Proven Reserves in 2013 

Petrobras announces the volume of its proven petroleum (oil and condensate) and natural gas reserves, assessed at the end of 2013 according to ANP/SPE (National Petroleum, Natural Gas and Biofuels Agency / Society of Petroleum Engineers) and SEC (Securities and Exchange Commission) criteria.

ANP/SPE Criteria: 

According to ANP/SPE criteria, on December 31, 2013, Petrobras' proven oil, condensate and natural gas reserves reached 16.565 billion barrels of oil equivalent (boe), representing an increase of 0.8% from 2012, as shown in Table 1:

During 2013, 1.141 billion boe were added to proven reserves. In that year, Petrobras sold its participation in fields with proven reserves amounting to 0.156 billion boe. The balance between incorporations and sales resulted in an increase of 0.985 billion boe to proven reserves, against a production of 0.861 billion boe. These volumes do not take into account the production of Extended Well Tests (EWTs) in exploratory blocks in Brazil or the production in Bolivia since the Bolivian Constitution prohibits the disclosure and registration of its reserves. The evolution of the proven reserves, according to ANP/SPE criteria, is shown in Table 2:

Apparent differences in the sum of the shares are due to rounding off. The highlights of 2013, in terms of the proven reserves in Brazil, were:  Declaration of commerciality at two Transfer of Rights areas of the Santos Basin pre-salt - Búzios field (Franco) and Sul de Lula field (Sul de Tupi): ­ A volume of 0.720 billion boe was appropriated to proven reserves in 2013 from these fields, corresponding to 23% of the volume contracted for these areas; ­ Petrobras has the right to extract up to 5 billion boe of petroleum from certain pre-salt areas acquired in 2010 through the Transfer of Rights Agreement. These new fields include the right to extract 3.186 billion boe, of which 3.058 billion boe from Búzios and 0.128 billion boe from Sul de Lula;

­ The remaining contracted volume for these two fields will be appropriated to proven reserves as projects are implemented.

 Declaration of commerciality of Lapa field (Carioca), in the Santos Basin pre-salt, under the concession regime;

 Declaration of Commerciality of Baúna Sul field, in Santos Basin, and Paturi and Maçarico fields, in the Potiguar Basin;

 Incorporation of volumes related to the discovery of new accumulations near existing infrastructure, as a result of the on-going success of exploratory activities in different Brazilian basins:

­ For the pre-salt, in the Albacora, Caratinga and Marlim Leste fields, in Campos Basin;

­ For the post-salt, in the Piracaba field, in Santos Basin, in the Taquipe and Araçás fields, in the Recôncavo Basin, and in the Rio Urucu field, in the Solimões Basin. The highlights of 2013, in terms of Petrobras' proven reserves abroad, were:

 Sale of 50% of the assets in Africa, by creating a joint venture for oil, condensate and natural gas exploration and production, and of interests in fields in the US Gulf of Mexico, amounting to 0.111 billion boe;

 Appropriations due to the extension of concessions in Argentina and of the execution of the well campaign planned for onshore fields in Argentina and offshore fields in the US Gulf of Mexico.

Note: The proven reserves (0.166 billion boe) of the assets sold by Petrobras in 2013 in Peru and Colombia remain recorded as such until the transactions are approved by the competent agencies.

For each barrel of oil equivalent extracted in 2013, 1.14 barrel was added, resulting in a Reserve Replacement Index (RRI) of 114%. In 2013, the Reserve/Production (R/P) ratio was 19.2 years, according to Table 3 below:

Reservas da Petrobras crescem em 2013 com impulso dos campos do pré-sal

Tribuna Hoje

A Petrobras informou nesta terça-feira que suas reservas provadas cresceram em 2013, impulsionadas pela declaração de comercialidade de alguns campos no pré-sal da Bacia de Santos, apesar da produção de mais de 800 milhões de barris no ano e da venda de participações em campos.
As reservas cresceram de 0,8 a 1,9 por cento ante 2012, dependendo do critério utilizado, com apropriações de mais de 1 bilhão de barris de óleo equivalente (boe).

"Para cada barril de óleo equivalente extraído no ano de 2013, foi apropriado 1,28 barril, resultando em um Índice de Reposição de Reservas (IRR) de 128 por cento", disse a estatal em comunicado, citando dados contabilizados pelo critério da Securities and Exchange Commission (SEC), o órgão regulador de mercados dos Estados Unidos.

A empresa afirmou que em 2013 a relação Reserva/Produção, pelo critério da SEC, ficou em 15,2 anos .
As reservas provadas de óleo, condensado e gás natural da Petrobras atingiram 13,123 bilhões de barris de óleo equivalente (boe), o que representa um aumento de 1,9 por cento em relação a 2012.
Desse total considerado pela SEC, cujo critério é mais rigoroso em relação à comercialidade das reservas, 12,540 bilhões de boe estão no Brasil e 583 milhões de boe no exterior.
Durante o ano de 2013, foi apropriado um volume de 1,218 bilhão de boe às reservas provadas, revelou a estatal.

Por outro lado, foram vendidas participações em campos com reservas provadas de 118 milhões de boe.

"O balanço entre apropriações e vendas resultou em um acréscimo de 1,100 bilhão de boe às reservas provadas, contra uma produção de 0,861 bilhão de boe", disse a estatal, ressaltando que os dados não incluem a produção na Bolívia e dos Testes de Longa Duração (TLD) em blocos exploratórios no Brasil.
A declaração da comercialidade nas áreas de Búzios (Franco) e campo Sul de Lula (Sul de Tupi), no pré-sal de Santos, colaborou fortemente para o aumento das reservas. Nestes campos, foi apropriado um volume de 720 milhões de boe como reserva provada em 2013.

Outro critério
Pelo critério da Agência Nacional do Petróleo, Gás Natural e Biocombustíveis/Society of Petroleum Engineers, as reservas subiram 0,8 por cento em 2013 ante 2012, para 16,565 bilhões de barris de óleo equivalente (boe).

O volume das reservas da estatal no Brasil somou 15,973 bilhões de boe em 2013. Em outros países, as reserva da Petrobras somaram 592 milhões de boe.

Pelo critério da ANP, a relação Reserva/Produção ficou em 19,2 anos, ante 15,2 anos pelo critério da SEC.
