22 February 2013, Sweetcrude, Nairobi – UK explorer, Tullow Oil, says flow tests result from its Twiga South-1 oil discovery in Kenya, showed a combined flow rate of 2,812 barrels of oil per day (bopd) from three reservoir zones.
In a statement released Thursday, Tullow added that the combined rate has the potential to flow at around 5,200 bopd. However, the company also said that its Ugandan Ondyek-1 exploration well did not encounter hydrocarbons.
Tullow said the Twiga South-1 results provide encouragement for the company’s forthcoming testing program at Ngamia-1A on Block 10BB, where four zones are planned to be tested using the Weatherford 804 rig. Testing activities here are expected to begin in March and be complete by the end of May.
Meanwhile, the firm said Ondyek-1 well in Uganda has now been plugged and abandoned after it failed to find hydrocarbons but that it is carrying out further evaluation of the nearby Lyec-1 discovery, with the partners on block EA-1A reevaluating the remaining exploration potential of the area.
Tullow Exploration Director Angus McCoss commented in a statement:
“While it is still early days for our exploration campaign in Kenya, these flow tests results at Twiga South-1 are an important step on the way towards understanding the commercial potential of the two discoveries we have made so far. The Ondyek-1 well in Uganda did not encounter hydrocarbons but has contributed much to our understanding of the limits of the EA-1A block.”
Tullow has a 50-percent operated interest in the Twiga South-1 well.
