UK independent Tullow Oil discovered three pay zones Tuesday during an onshore Kenya well drilling program.
Tullow has completed extended well testing at its Amosing-1 and Amosing-2A at blocks 10BB and 13T in the South Lokichar Basin.
Initial rig-less clean-up testing has been concluded on both wells with “excellent” results.
The Amosing-1 well flowed at a combined maximum rate of 5,600 bopd from five zones and the Amosing-2A well flowed at a combined maximum rate of 6,000 bopd from four zones, the fifth zone being in the aquifer.
Both wells demonstrated “high quality” reservoir sands and flowed 31 to 38 degree API dry oil under natural flow.
Tullow said the findings support static pressure data indicating connectivity between the Amosing-1, 2, 2A and 3 wells in multiple zones.
The company will now perform longer-term oil flow and water injection tests expected to start in the middle of March with results expected during the second quarter.
Tullow also discovered a pay zone at its recently drilled Ngamia-7 appraisal well.
The well was drilled to a final depth of 9,560 feet to test the Ngamia oil field’s eastern flank, located 5,905 feet north-east of Ngamia-1 and 4,265 feet east of Ngamia-3.
The well encountered up to 433 feet of net oil pay and has expanded the proven extent of the field.
The well has now been suspended for future use.
“There is further good news from our appraisal programme in Northern Kenya where the Ngamia-7 well has successfully tested and extended the eastern flank area of the oil field,” Tullow exploration director Angus McCoss said.
Tullow drilled dry at its Engomo-1 exploration well in Block 10BA.
The well was drilled to a total depth of 7,719 feet using the SMP-106 rig and encountered no significant oil or gas shows were encountered.
The well has been plugged and abandoned.
Tullow operates blocks 10BB, 13T and 10BA with a 50 percent equity stake.
British Colombia-based Africa Oil Corporation holds the remaining 50 percent stake.
