Tullow Oil unveils exploration results of Kenyan onshore wells

Tullow Oil has unveiled the results of a series of exploration and appraisal activities undertaken in Blocks 10BB and 13T onshore Kenya.

The initial well drilled was the Kodos-1 exploration wildcat in Block 10BB in the Kerio Basin, northeast of the South Lokichar Basin.

Tullow Oil encountered hydrocarbon shows in Kodos-1, which suggets the presence of an active petroleum system. The reservoirs however were of mixed quality alluvial sands close to the basin boundary fault at the well location.

Tullow Oil said the second well, Ekosowan-1, in block 10BB is the most southerly well drilled to date in the South Lokichar Basin, 12 km south east and up-dip of the earlier Amosing-1 oil discovery.

The well encountered a 900m section of near continuous oil shows across an interval of tight faulted sands.

The Ekosowan area is situated within the ongoing 3D seismic survey in the South Lokichar Basin, acquisition of which, is anticipated to be completed in December 2014.

The Ngamia-4 well in Block 10BB encountered about 120m of net hydrocarbon pay, of which around 80m was oil.

The company suspended the well for use in future appraisal and development activities.

The SMP-5 Workover Rig has completed four flow tests on the Twiga-2A well in Block 13T, achieving production rates between 150 and 3,270 bopd under natural flow with no depletion.

The company said the maximum flow potential from the best zone could have increased to about 10,000 bopd with optimised equipment.

Tullow Oil operates blocks 10BB and 13T with 50% stake while Africa Oil holds the remaining stake.
