Despite the limited information released on upstream activity in Sudan, Wood Mackenzie estimates that value has been created from ongoing exploration in the Muglad - Sudd Rift Basin, where over 220 exploration wells have now been drilled. We expect the majority of future discoveries to be small-to-medium sized pools. Most of the oil exploration areas in Sudan are flooded during the rainy season, which typically lasts from April to October. Elevated roads and drilling pads are therefore often required in order to sustain year-round exploration and development activities, and these harsh operating conditions and the remote location of the basin drive up costs. Despite this, the export infrastructure has spare capacity and new finds could achieve short lead times, allowing good retruns. Opportunities to access the basin should become available over the next five years, as a number of the large existing licences that cover almost all the basin will in theory expire.
