Tecpetrol, PetroNova make Llanos heavy oil find

Tecpetrol Colombia has made a heavy oil discovery at the Pendare-1 exploratory well on the CPO-13 block in the Llanos basin in Colombia.

The well logged a 39-ft gross oil column in basal Carbonera sand and produced at the rate of 166 b/d of fluid, 15% BS&W. Total recovery was 366 bbl of 14.4° gravity oil.

Pendare 1 is the sixth of a nine-well exploratory campaign on the CPO-06, CPO-07, and CPO-13 blocks operated by Tecpetrol in which PetroNova Inc., Calgary, has 20% working interest. Total depth is 3,265 ft.

The well could yield higher volumes if equipped with an electric submersible pump, PetroNova said. It is to be completed in the top of the basal Carbonera sand unit and an extended production test will be performed after all required permits are obtained.

The exploratory campaign will resume in 3 months when weather allows cost-efficient access to new locations and all required permits have been received, PetroNova said.

Due to the successful results obtained to date, an overall success rate of 50%, PetroNova will incorporate additional prospects and has made an agreement to extend the rig contract.
