Exploration company Tullow Oil has announced an oil find at its Ngamia-1 well in Kenya.
The company said the oil had similar properties to the light waxy crude it has discovered in Uganda.
The Ngamia structure is the first prospect to be tested as part of a multi-well drilling campaign in Kenya and Ethiopia.
Tullow says the outlook for further similar prospects has "significantly improved" following this discovery.
Tullow has a 50% operated interest in multiple licences in the Kenya & Ethiopia Rift Basins covering more than 100,000 square kilometres.
"This is an excellent start to our major exploration campaign in the East African rift basins of Kenya and Ethiopia. To make a good oil discovery in our first well is beyond our expectations and bodes well for the material programme ahead of us," said Tullow's exploration director Angus McCoss.
