HOUSTON, May 11
– Madalena Ventures Inc., Calgary, said its Argentine subsidiary has cased the CAN X-4 exploratory well on the Coiron Amargo block in the Neuquen basin as a potential oil discovery.

Cased to TD of 11,027 ft, CAN X-4 had oil and gas shows while drilling the Vaca Muerta and Sierras Blancas formations. Based on electric logs, the Vaca Muerta had similar thickness and characteristics to the other four wells Madalena has drilled on the block. Sierras Blancas had a 92-ft potential gross hydrocarbon column.

CAN X-4 is on a separately defined 3D drilling anomaly between the CAN X-1 and CAN X-2 wells.

Completion operations have started at the CAS X-1 well drilled in April 2011 in the southern part of the block to test the same two formations. Part of the test is expected to include a fracture stimulation of the Vaca Muerta formation. Combined test results will be reported as soon as available. CAN X-4 is to be tested next.
