Tullow' s Kenya discovery has constrained flow of 2,812 bopd
BY ED BALLARD
LONDON -- Tullow Oil completed the flow tests at the Twiga South-1 oil discovery in Kenya, reporting a constrained combined rate of 2,812 bopd from three reservoir zones, and added that, unconstrained, the combined rate has the potential to flow at around 5,200 bopd.
In Uganda, the Ondyek-1 exploration well did not encounter hydrocarbons. Flow constrained by surface equipment with optimised equipment, these flow rates would increase to a cumulative rate of around 5,200 bopd.
A progressive cavity pump (PCP) was used to artificially lift at DST 5, whilst DST 3 flowed naturally. Two additional zones were tested in the tight reservoir rock at the base of the well and, as anticipated, both produced at sub-commercial rates but confirmed the presence of movable oil.
According to Tullow, results provide encouragement for the forthcoming testing program at Ngamia-1A, Block 10BB, where four zones are planned to be tested using the Weatherford 804 rig. Testing activities are expected to start in March and complete by the end of May.
Ondyek-1 well on EA-1A Block was drilled to a total depth of 1,462 m; has been plugged and abandoned; further evaluation is being carried out on the Lyec-1 discovery. Partners are re-evaluating the remaining exploration potential of the area in light of recent well results.
