The appraisal well BRS-6bis was spudded on October 6, 2005. The well was drilled to a total depth of 3,937 meters. The final test confirms the hydrocarbon potential of Hamra Quartzite in Bir Seba structure with a maximum flow rate of 5,100 barrels of crude oil per day (44o API) and 4.8 million cubic feet of natural gas per day.
