Río Negro Approves First Unconventional Concession at Loma Guadalosa for PAE–Tango

The 35-year Cench under Decree 827/25 sets fiscal terms that grant Edhipsa a 2.5% share of output.

Pan American Energy (PAE)

Overview

  • Pan American Energy will operate with a 65% stake while Tango Energy holds 35% under the reconverted area.
  • The partners committed US$36 million to a three-year pilot of two 3,000-meter lateral horizontal wells, with the first well slated for 2026 and potential scale-up to as many as 44 more depending on results.
  • The project targets the Vaca Muerta formation in the eastern Neuquén Basin, with Loma Guadalosa spanning 101 km² about 60 km north of Cipolletti.
  • The reconversion was requested under the Federal Hydrocarbons Law, Law 27.742 and National Decree 1057/24, supported by prospective resources estimated at 48 mmboe.
  • The concession extends Vaca Muerta-style development beyond Neuquén into Río Negro as Tango shifts toward non-conventional assets following its recent restructuring.
