Argentina's state firm YPF was at the point of completely shutting down oil and gas production throughout Neuquén province after indigenous Mapuche residents blocked access to to wells for 48 hours to press demands over territorial rights. The blockades were lifted Sept. 4 after a hectic days of dialogue with Mapche leaders. The blockade was undertaken by the Mapuche community of Paynemil to press authorities to complete a demarcation of traditional indigenous lands in the area, as mandated by National Law 26.160 of 2006 but still not carried out. Hundreds of wells at the Loma La Lata, Rincón del Mangrullo and Loma Campana fields were affected by the action, supposedly costing YPF millions of dollars. July saw similar protests, when the Loma Campana field was blocked by members of the Mapuche community of Campo Maripe. The issue has been outstanding for years, but the new blockades marked the first time that hydrocarbon production throughout the province was affected. (InfoBae, InfoBae, Cronista, Sept. 4; Cronista, Diario Norte, July 30)
