Americas Petrogas, Inc. was a Canadian exploration and oil production company active in Argentina's Neuquén Basin.

[3][4] In 2004, Americas Petrogas was founded by oil and gas entrepreneur Barclay Hambrook[5][6] and his long-time business partner Carlos Lau.

They also considered the fiscal regimes, the geology, and access to infrastructure to enable early asset monetization for oil and gas discoveries.

They chose the site at Neuquén Basin, where oil had been discovered over 100 years ago, as its geological setting was similar to that of Western Canada, and only a tiny fraction of wells had been drilled historically.

Americas Petrogas is now one of the largest landholders in the Neuquén Basin with almost 900,000 net acres spread over 12 large blocks, 11 of which the company operates.

[7][10] In 2013, an independent Houston engineering firm, Ryder Scott, provided Americas Petrogas a Resource Report on the company's unconventional blocks.
