Andes Energia has completed an intervention operation on the VG x-1 well in Argentina, testing the Vaca Muerta formation, which is currently producing 80 bbl/d of oil without a hydraulic fracturing stimulation.
Andes owns and operates the VG x-1 well, which is located on the Vega Grande oilfield in the Neuquén basin, Mendoza Province.
The Vega Grande licence covers a total area of 72,000 acres and is located in the north of the Vaca Muerta play, close to the La Brea licence, which is also 100% owned and operated by Andes.
Combined, the two licenses cover a total area of 105,000 acres, representing about 42% of net acreage in Vaca Muerta to Andes.
Andes Energia CEO Alejandro Jotayan said: "This production test in Vaca Muerta is a meaningful advance in the development of our shale acreage.
"We are already producing from shale without needing to frack, reducing costs and the necessary break-even oil price. It de-risks 30% of Andes’ net acreage in Vaca Muerta, more than doubling our already de-risked acreage; and is the first Andes operated intervention and production test in Vaca Muerta."
