Tullow Oil announced that the Likonde-1 well, onshore Tanzania, has encountered thick sands with hydrocarbon shows. The well, which is now being plugged and abandoned, is the first of a two-well programme within the prospective Ruvuma delta region. The group said the 'encouraging results' will be followed up with detailed technical work prior to selecting the next drilling location. "Likonde-1 is an encouraging well with follow-up exploration potential. The valuable technical insights gained are now being incorporated into our regional geological model to further evaluate this promising basin in Southern Tanzania," said exploration director Angus McCoss.
