Gas markets are becoming increasingly important around the world and the long-term evolution of these markets is of strategic importance for many countries. This makes it essential to understand how regulation and intervention in these markets affects the long-term prospect for the secure supply of gas. We use Argentina as a case to illustrate some of the issues and consequences of gas regulation. Argentina is a country that has had a significant increase in the use of gas over the years, and where a potential gas deficit looms large in the present and the future. Based on a simulation model developed to understand the supply of gas in Argentina, we discuss how regulation will influence the long-term supply of gas in both Argentina and surrounding countries. Using the model, we develop a series of scenarios to highlight the consequences of different current and possible future interventions in the market by the Regulator. Finally, we discuss short-term regulatory options to reduce the impact of a gas deficit, and the possibility of securing the long-term supply of gas in Argentina. © 2010 Elsevier Ltd.

The eastern Andean slope from 34° to 37°S has a unique character when compared to neighboring sectors: Lower Miocene volcanic rocks cover upper Cretaceous to Eocene contractionally deformed deposits in the retroarc area. Remnants of the previous upper Oligocene arc front are found at the present-day western Andean slope, west of the mentioned Miocene arc sequences. These lavas and ignimbrites of the Charilehue Formation, typically described as an arc suite, have ages between 18 and 14.5. Ma and thickness over 1000. m, and are delimited by normal faults. Chemical analyses reveal that they have an anomalous chemistry characterized by poorly evolved mantle-derived rocks, which differ from Eocene and Late Miocene typical arc magmas in the region. Their spatial distribution depicts a NE trend more than 100. km long, whose outcrops were affected by Middle to Late Miocene compressional deformation and subsequent exhumation, as shown by field and fission track data. The Charilehue volcanic sequences represent the westernmost products of an incipient and poorly evolved arc that migrated and expanded to the foreland, initially coexisting with an extensional setting inherited from late Oligocene times. This complex evolution is interpreted as the result of a slab shallowing related to the time when the South American plate started its westward absolute shift after a quasistatic period in the Oligocene. The shift of the magmatism to the foreland probably caused a higher thermal gradient and, therefore, a shallower brittle-ductile transition that triggered thick-skinned basement tectonics in the retroarc region, reactivating Late Cretaceous to Eocene décollements. © 2011 Elsevier Ltd.

BUENOS AIRES, Argentina (AP) — Argentina's state-run YPF energy company is following an order by the country's Supreme Court to disclose to the court clauses of an investment deal with U.S.-based Chevron Corp. in one of the world's largest shale deposits. YPF delivered a copy of the contract to a Buenos Aires court on Tuesday. It's uncertain whether all clauses of its deal with Chevron to produce oil and gas by hydraulic fracturing in southern Neuquen province will become public. YPF said in a statement it's concerned about releasing confidential information that could affect the deal and place the company in a disadvantageous position with its competitors and shareholders. The Supreme Court ordered YPF to release the information in November after the company refused to disclose environmental and other information to a local lawmaker.

YPF SA and American Energy Partners LP have signed a joint venture agreement to explore and develop unconventional oil and natural gas from Argentina’s Vaca Muerta formation providing that financing can be arranged.

Argentina's Supreme Court, pictured on October 29, 2013, has ordered the government to publish details of an agreement between the state-run oil company and US petrochemical giant Chevron (AFP Photo/Juan Mabromata) More Buenos Aires (AFP) - Argentina's top court Tuesday ordered the government to publish details of a deal state oil company YPF struck with US giant Chevron to exploit shale reserves in the South American country. The ruling followed allegations of secret clauses in the 2013 deal linked to the exploitation of the Lomo Campana shale deposit, which YPF says is the biggest non-conventional oil reserve outside North America. The Supreme Court of Justice said in a statement it "ordered YPF to make public the clauses of the investment project agreement signed with the Chevron Corporation." The court said YPF had previously refused to respond to its demands for information about the likely environmental impact of operations under the deal. YPF said in a statement it would comply with the court order. It said Chevron has invested more than $2.5 billion in Lomo Campana, part of the vast Vaca Muerta shale field in southwestern Argentina. YPF owns a third of Vaca Muerta overall.
