The overall oil column for the field is considered to be 100m to 125m.
Tullow Oil exploration director Angus Mccoss said: “This is an exciting discovery from a bold exploration well that proves that oil has migrated to the northern limit of the South Lokichar basin.
“This extends the known hydrocarbon limits of the basin beyond the successful Etom discovery into the underexplored northern part of the basin where we have several undrilled prospects. Following the scheduled appraisal wells at Amosing-6 and Ngamia-10, further exploration drilling of this area is now being planned.”
The well targeted a structural trap at the northern limit of the South Lokichar basin.
