Shell announces Gabon deep-water gas discovery Shell (RDS.A, RDS.B)announced a frontier exploration discovery offshore Gabon, West Africa. The well Leopard-1 encountered a substantial gas column with around 200 metres net gas pay in a pre-salt reservoir. Leopard-1 is located around 145 kilometres off the Gabonese coast, west of Gamba. It was drilled in water 2,110 metres deep to a total vertical depth of 5,063 metres. Shell and partners are planning to undertake an appraisal programme to further determine the resource volumes. Leopard-1 was drilled in license BCD10, operated by Shell. Second partner in the venture is CNOOC (CEO). This frontier discovery follows recent deep water exploration successes in the heartlands for Shell Exploration in the Gulf of Mexico and Malaysia.
