The Argentinian Member Committee reports data provided by the Secretaría de Energía that indicate a further reduction in the republic’s gas reserves. At the end of 2008, proved recoverable reserves stood at 399 bcm, 9.1% lower than the end-2005 level of 439 bcm adopted for the 2007 Survey. The same source states that ‘probable reserves’, not yet proven but considered to be eventually recoverable, now stand at 139 bcm, while possible reserves amount to a further 197 bcm. Potential additional recovery from known resources is put at some 245 bcm, representing an increase of around 33% on the total of reported recoverable reserves.

Gas extraction takes place in five sedimentary basins. In 2009 the largest share of production came from the Neuquina Basin which provided 56% of the total, followed by the Austral Basin with 20%, the Northwest Basin with 13% and the Golfo San Jorge with 11%; the contribution of the Cuyana Basin is minimal. Less than 2% of current gross production is re-injected. Marketed production (after relatively small amounts are deducted through flaring and shrinkage) is the highest in South America.

For many years, gas supplies have been augmented by imports from Bolivia, but this flow ceased in October 1999, as the focus of Bolivia’s gas exports shifted to Brazil. In a further reorientation of the South American gas supply structure, Argentina has become a significant exporter in its own right, with a number of pipelines supplying Chile and others to Uruguay and Brazil.

Consumption of indigenous and imported gas in 2007 was divided between the power generation market (35%), industrial fuel/feedstock (24%), residential/commercial uses (24%) and gas industry own use/loss (10%); about 7% was consumed as CNG in road transport.
