Toranado-1 well in Argentina' s Guaco prospect encounters water-bearing reservoirs

CALGARY -- PetroNova provided an update on its Tornado-1 exploration well located on the CPO-13 block in which PetroNova has a non-operating, 20 % working interest in Colombia' s Llanos Basin.

The Tornado-1 exploration well, spud on December 11, 2012, reached total depth of 3,315 ft on December 16, 2012. Good sand development was encountered in both target zones, the Basal sands of the Carbonera formation and the Eocene Mirador formation. Despite some oil shows in the Mirador Sand sequence, wireline logs acquired after drilling measured low resistivities in both formations and the identified reservoirs were interpreted as water bearing. Tornado-1 will be plugged and abandoned.

Tornado-1 is the third well drilled in the CPO-13 Block, where a discovery at the Pendare-1 well was announced on July 25, 2012. Drilling the Tornado-1 well fulfilled the obligations of PetroNova and the operator under the Phase 1 exploration program, required in the exploration and production contract with the ANH and Phase 1 is now complete.PetroNova and the operator will continue their drilling campaign and plan to move the rig to the Guasco Prospect in the CPO-13 Block.
