According to the British based exploration firm, the flow of the oil at Block 10BB was after the completion of the first drill test at Lower Lokhone formation.
In February, Tullow announced results from Twiga South-1 well showing a production of 2,812 barrels of oil per day.
Twiga South-1 well is about 30km west of Ngamia-1 well where Tullow struck oil earlier in 2012.
“At the Ngamia-1 well in Block 10BB in Kenya, the first of six drill stem tests has now been completed. The well flowed 281 barrels of 30 degree API oil per day using a Progressive Cavity Pump,” statement from the firm read on Monday.
Whilst both the Ngamia and Twiga South discoveries have exceeded expectations and substantially de-risked further prospects in the South Lokichar Basin, the firm said it will require considerably more exploration and appraisal activity to be completed before the commercial threshold for the basin is achieved.
The mobilisation of the drilling rig from Paipai in Block 10A to the Etuko location in Block 10BB in Kenya continues on schedule with drilling expected to commence in the first half of May this year.
Meanwhile the Sabisa-1 well in the South Omo Block in Southern Ethiopia has been drilled to a total depth of 1,810 metres with results also expected in May.
The firm has been licensed to operate all seven of these blocks and has a 50 percent interest in six of them.
