PetroNova Inc. provided an update on its Tornado-1 exploration well located on the CPO-13 Block (in which PetroNova has a non-operating, 20 percent working interest) in Colombia's Llanos Basin.

The Tornado-1 exploration well, spud on December 11, 2012, reached total depth of 3,315 feet 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.
