After drilling Likonde-1, Solo has earned the right to participate in any further drilling on the licences covered by the Ruvuma PSA through contributing 12.5% of ongoing costs. On completion of the conditions referred to above, Solo will become a full party to the Ruvuma joint operating agreement with interests in the PSA held as follows:

Information on the Ruvuma PSA

The Ruvuma PSA covers 12,360 sq kilometres in the extreme south-east of Tanzania, of which roughly 80% is onshore and 20% offshore. Within the PSA are two specific, adjoining licence areas, Lindi and Mtwara. The first well under the Ruvuma PSA has been drilled on the Likonde prospect.

As announced on 1 April 2010, the Likonde-1 well encountered thick reservoir sands with shows of both oil and gas and was terminated in the deepest objectives due to high gas.

The well, which was plugged and abandoned, is the first of a two-well programme on the PSA and the encouraging results will be followed up with detailed technical work prior to selecting the next drilling location.
