Corcel plc said testing had started on the Tobias-14 (TO-14) well on block KON-11, onshore Angola.
Operator Sonangol faced delays due to longer than expected wait for deliveries of testing equipment, combined with heavy rains and regional flooding at the well location.
Once testing is complete, the equipment will be moved to flow test TO-13 where the well pad is currently being prepared.
Initial results for TO-14 are expected over the next several weeks.
Corcel holds a 20% working interest (18% net) in the project.
