Swala Oil and Gas Tanzania has successively completed its 430-km seismic programme over the Kilombero Basin with the data being processed of detailed interpretation aiming to map additional potential drilling targets.In a statement made available to the Daily News, the seismic programme identified a series of structural leads on the western margin of the basin.
“This is a major achievement of Swala as we have now fully met our work programme commitments for the past three years on the Kilosa - Kilombero Production Sharing Agreement (PSA) exploration area.
“We are now looking forward to the results of the detailed mapping, basin modelling and seismic amplitude anomalies before targeting our drill candidate,” the Swala Chief Executive Officer, Dr David Ridge said in the statement.
Dr Ridge said that they were granted the licence, no hydrocarbon exploration activity had ever before been carried out in the area and that they have new broken ground proving three sedimentary basins and in the Kilombero basin, multiple structural leads and prospects in a young neogene basin.
Swala has already identified the Kito prospect, with estimated 60.4 million barrels having 50 per cent certainty of being produced or P50 best estimate prospective resources, as potential drilling target for 2015.
In October last year, Swala Energy announced that its seismic survey being carried out in the Kilombero Basin had provided the first evidence of multiple structures - a “string of pearls”- along the western basin boundary.
“These early results of the Kilombero seismic survey are particularly exciting and the similarities with the Lokichar Basin are extremely encouraging given the enormous success that has been achieved there to date,” Dr Ridge was quoted to have said.
“The seismic survey has so far identified five possible structures in addition to the Kito Prospect and we believe further dip lines will cement these into firm drilling candidates and that the extension of Line 101 further north will result in more structures being identified.”
The first line of the current seismic survey acquired in the Kilombero Basin, Line 101, extends along the strike of the main bounding fault.
Initial interpretation of the data suggests the presence of four new structures, each being 5-10-kilometre long.
At the northern end of Line 101, just beyond the Kito Prospect, the data show that one of the identified reservoir horizons is rising, potentially indicating the presence of another structural closure. Swala has a 29.2 per cent net interest in the Kilosa- Kilombero licence in central Tanzania.
