Tullow Oil has abandoned a well in the South Omo block onshore Ethiopia.
Following drilling to a depth of 2,101 metres, Tullow decided to plug and abandon the Tultule-1 wildcat well, after it came up dry.
The well had been targeting a reservoir section similar to the sands drilled in the nearby Sabisa-1 well where oil shows were encountered.
Despite finding no oil, gas was detected reaffirming the presence of a hydrocarbon source in the region.
Tullow, which operates the well with a 50% interest alongside partners Africa Oil (30%) and Marathon (20%), says findings from both wells will now be analysed to determine future exploration in the area.
The exploration rig will now move to the Chew Bahir basin in Ethiopia to drill the Shimela prospect in the eastern part of the South Omo block.
Tullow says new seismic suggests a number of exciting new prospects in the area. The well is expected to be spud at the end of Q1 2014.
Providing an update on operations in Kenya, the company said “significant exploration activity” was ongoing in Block 10BB with the Amosing-1 well currently drilling and the Ewoi-1 expected to be spud by the end of the year.
Preparations were also underway for flow tests following discoveries made at the Etuko-1 and Ekales-1 wells. Tullow said results from these tests were expected early in the first quarter of 2014.
