HOUSTON, Sept. 27 – Madalena Ventures Inc., Calgary, cased its CAN X-1 exploratory well on the Coirin Amargo block in Argentina’s Neuquen basin as a potential oil discovery.
The well is on a 3D anomaly midway between the CAN X-3 well drilled in August 2010 and the CAN X-2 discovery well drilled in 2009.
The CAN X-1 well targeted the Sierras Blancas formation. TD is 10,930 ft.
The well encountered several zones with hydrocarbon potential. Based on electric logs, the Sierras Blancas formation encountered a gross hydrocarbon column of 65 ft. The Vaca Muerta formation had a gross hydrocarbon column similar to that encountered at CAN X-3 of approximately 110 ft.
Drilling and electric log data also indicate potential for hydrocarbons in the Lotena formation below the Sierras Blancas formation. A completion rig is being mobilized this week to test the Sierras Blancas formation encountered by the CAN X-3 well followed immediately by the CAN X-1 well.
Meanwhile, the drilling rig contracted to drill the Curamhuele X-1001 exploratory well (truncation play) is expected to be onsite early October, 2010. The well is projected to 8,850 ft to penetrate the Lower Troncoso and Avile formations, the main productive horizons in El Trapial, Chihuido de la Sierra Negra, and Lomita Sur fields 20-30 km east of Curamhuele.
