Angola- focused exploration and production company, Corcel, has announced an update on Tobias field reactivation activities in Block KON-11 in the Kwanza Basin, onshore Angola 

Corcel has a 20% working interest (18% net), while the operator is Sonangol.

Sonangol has reported the conclusion of initial well test efforts at the TO-14 well in Block KON-11 with ongoing engineering work set to continue. Well clean-up operations using nitrogen resulted in significant water production with oil shows and nominal oil saturation levels.

Together with the Block Partners, and given shortages of nitrogen in Luanda, the operator has decided to move to testing the TO-13 well, which has been drilled in what is considered the least drained section of the reservoir and historic field.

The equipment move is expected to take approximately seven days after which formal testing will begin. Subject to a successful well test at TO-13 and related engineering studies, the operator intends to return to TO-14 and continue well clean-up and testing operations.

Additional updates on the Tobais field reactivation and testing program will be provided in due course.

Corcel executive chairman, Antoine Karam, commented, 'With TO-13 testing shortly to commence, we will soon have an additional data set to aid in our efforts to both produce commercial oil in the short term and to reactivate and build out the Tobias field over the longer term. The Company and its technical team remain buoyant regarding the ongoing potential of our Angolan interests in the Kwanza Basin.'
