Americas Petrogas Announces Huacalera Shale Pilot Well Cased, Vaca Muerta Thickness 1,742 Feet

CALGARY, ALBERTA--(Marketwire - Aug. 2, 2011) - Americas Petrogas (TSX VENTURE:BOE) ("Americas Petrogas" or the "Company") is pleased to announce that the Hua.x-1 well on the Company's Huacalera Block, operated by the Company's joint venture partner, Apache Argentina, has reached total depth (TD) of 4100 metres (13,450 feet). A full suite of logs, including image logs, has been run and production casing has been successfully set all the way to TD.

The primary target Vaca Muerta Shale Formation (531 metres or 1,742 feet approximate gross thickness) has initial indications of overpressure. Gas shows were encountered in the Mulichinco Formation (140 metres or 459 feet approximate gross thickness), the Quintuco formation (414 metres or 1,358 feet approximate gross thickness) through the Vaca Muerta Formation and into the Tordillo Formation, and these results were reported to the appropriate government authorities.

The comprehensive suite of logs and mud log information will now be integrated and interpreted. The vertical cores, sidewall cores and rock cuttings have been sent to 3 different laboratories for analysis to measure the petrophysical and geochemical characteristics of the samples, both shales and sands. The results, which are expected during Q3-2011, will provide fracing and testing options for tight sands and shale gas or oil reservoirs.

This is the first Vaca Muerta Shale gas pilot exploration well drilled in the 250,000 acre (390 sections) Huacalera block which lies along the emerging shale gas and shale oil play corridor in the western part of the Neuquen Basin, Argentina. As previously stated, Americas Petrogas has a 39% Working Interest in this large block and is carried 100% on the Hua.x-1 well by Apache.

Commenting on the drilling of this well, Mr. Barclay Hambrook, President and CEO, stated, "We are very pleased that the well has been drilled and cased successfully and, with Apache, we are looking forward to the results of fracing, testing and further exploration on this very large and promising block. Huacalera occupies a strategic location almost midway between our 5 northern blocks and 3 large southern blocks along the emerging shale play corridor."

About Vaca Muerta Shales

The Vaca Muerta Shale is one of two principal source rocks in the Neuquen Basin of Argentina. The shale is late Jurassic-early Cretaceous in age, covers an area of approximately 8500 square miles, varies in depth between 5,500 to 14,000 feet and in places is up to 2,000 feet in thickness.

The Vaca Muerta characteristics are believed to be similar to shale reservoirs such as the Eagle Ford, Haynesville and Horn River in North America which have so far resulted in discoveries of both shale gas and shale oil. The shale has recently become the focus for many of the important shale gas players in North America, including Apache, Exxon Mobil, Total as well as YPF in Argentina.
