The Orinoco Belt is a territory which occupies the southern strip of the eastern Orinoco River Basin in Venezuela. Its local Spanish name is Faja Petrolífera del Orinoco (Orinoco Petroleum Belt).

The Orinoco Belt is located south of the Guárico, Anzoátegui, Monagas, and Delta Amacuro states, and it follows the line of the river. It is approximately 600 kilometres (370 mi) from east to west, and 70 kilometres (43 mi) from north to south, with an area about 55,314 square kilometres (21,357 sq mi).


Oil reserves

The Orinoco Belt consists of large deposits of extra heavy crude (oil sands), known as the Orinoco Oil Sands or the Orinoco Tar Sands. The Orinoco Tar Sands are known to be one of the largest, behind that of the Athabasca Oil Sands in Alberta, Canada. Venezuela's non-conventional oil deposits of about 1,200 billion barrels (1.9×1011 m3), found primarily in the Orinoco oil sands, are estimated to approximately equal the world's reserves of conventional oil.[1] Petróleos de Venezuela S.A. has estimated that the producible reserves of the Orinoco Belt are up to 235 billion barrels (3.74×1010 m3)[2] which would make it the largest petroleum reserve in the world, before Saudi Arabia [3].

In 2009, USGS updated this value to 513 billion barrels (8.16×1010 m3)[4]. It is currently divided into four exploration and production areas. These are: Boyacá (before Machete), Junín (before Zuata), Ayacucho (before Hamaca), and Carabobo (before Cerro Negro). The current exploration area is about 11,593 km².


Oil Sowing Plan 2005-2030

Venezuela power policy guidelines until the year 2030 are drawn up in the "Oil Sowing Plan” ("Plan Siembra Petrolera"), which includes six development projects and consists of two stages: one to be executed in the period 2005-2012, and another, to be developed in the second stage, 2012 and 2030.

For the first period of this Plan, an overall investment of around US $56 billion[citation needed] has been estimated between 2005 and 2012. 70% of that amount will be financed by Venezuela — state operator — and the rest by the private sector.

Oil Sowing Plan 2005-2012 includes six fundamental axes:

  1. Magna Reserve: Destined toward the quantifying and certifying of oil reserves in the Orinoco Oil Belt. In a presentation given by PDVSA (held by Director Ignacio Layrisse) at the VII LAPEC conference in Buenos Aires, March 2001, the proven Venezuelan reserves were given as 76 billion barrels (1.21×1010 m3). Of this amount 52 billion barrels (8.3×109 m3) were heavy or extra heavy oil, including 37 billion reserves of extra heavy in the Orinoco Belt (1 in Machete, 15 in Zuata, 6 in Hamaca and 15 in Cerro Negro). This indicates that Venezuela’s reserves, according to PDVSA, in 2001 were 39 billion barrels (6.2×109 m3) excluding the Orinoco Belt.
  2. Orinoco Project: In charge of developing the Orinoco Belt. Twenty-seven blocks have been selected for development under this project with the cooperation of selected companies. Because of the strategic location of this hydrocarbon reservoir, it is considered of vital importance in reducing levels of overcrowding in some parts of the country and providing local employment. Services and housing will be developed to guarantee adequate oil exploitation.
  3. Delta-Caribbean Project: Gas will be incorporated to the country energy supply. This project pursues offshore gas development in the Deltana Platform off the coast of eastern Venezuela. Further developments are located in the Paraguaná Peninsula, to the north-west of the country.
  4. Refinement: To increase refinement capacity in Venezuela is one of PDVSA’s strategic goals. Oil Sowing Plan undertakes the creation of new refineries: Cabruta (with capacity for 400,000 extra-heavy crude barrels per day), Batalla de Santa Ines (50,000 barrels (7,900 m3)) and Caripito (50,000 barrels per day (7,900 m3/d) destined to asphalt production). With these three new refineries and the improvement of the existing ones, PDVSA’s processing capacity on Venezuelan soil will be increased to 700,000 barrels per day (110,000 m3/d).
  5. Infrastructure: More filling centers and pipelines will be set up to guarantee fuel supplies to the whole nation. The agreement for the construction of the Transguajiro gas pipeline between Venezuela and Colombia has been signed in 2005.[5]
  6. Integration: According to Hugo Chavez's aims, oil is to be used as a geopolitical resource helping the integration of the peoples of Latin America and the Caribbean. Venezuela thus created Petrocaribe and signed the Petrosur agreement. A refinery was also to be built close to Petrobras in Brazil.

Production blocks

Production blocks will be developed by PDVSA in cooperation with foreign partners. In all partnership PDVSA owns 60%.[6]


Junin block 2 is under development in cooperation with Petrovietnam. SNC-Lavalin was awarded the engineering contract on March 10, 2010. It is expected to produce 200 thousand barrels per day (32×10^3 m3/d) by 2011. The development will include also a heavy crude upgrader; however, its commissioning date is not specified. Junin block 4 is developed in cooperation with CNPC (40%). It is expected to produce 400 thousand barrels per day (64×10^3 m3/d); however, the commissioning date is not announced. Junin block 5 is developed in cooperation with Eni (40%). It is expected to produce 75 thousand barrels per day (11.9×10^3 m3/d) by 2013 with late production of 240 thousand barrels per day (38×10^3 m3/d). The development will include an oil refinery for production of motor fuels. Junin block 6 is developed in cooperation with a consortium of Russian oil companies, including Rosneft, Gazprom Neft, Lukoil, TNK-BP and Surgutneftegaz. It is expected to produce 450 thousand barrels per day (72×10^3 m3/d); however, the commissioning date is not announced.[6]

There is no foreign partner yet for Junin 1, 10, and 11 blocks — all with expected production capacity of 200 thousand barrels per day (32×10^3 m3/d).[6]


Carabobo 1 is developed in cooperation with Repsol YPF (11%), Petronas (11%), ONGC (11%), Indian Oil Corporation (3.5%), and Oil India (3.5%). It consists of Carabobo block 1 North and block 1 Central. The expected production output will be 400 thousand barrels per day (64×10^3 m3/d) by 2013. The upgrader is expected to be ready by 2017.[6]

Carabobo 3 is developed in cooperation with Chevron Corporation (34%), Suelopetrol (1%) pct, and Mitsubishi Corporation and Inpex (5%). It consists of Carabobo block 2 South, block 3, and block 5. The expected production output will be 400 thousand barrels per day (64×10^3 m3/d) by 2013. The upgrader is expected to be ready by 2017.[6]

There is no foreign partner for Carabobo 2 yet.[6]
