Tullow Oil PLC, London, reported recent exploration and appraisal results from Blocks 10BB and 13T onshore Kenya.

The Etom-1 exploratory well on Block 13T in the South Lokichar basin, some 6.5 km north of the Agete-1 discovery (OGJ Online, Nov. 22, 2013), was drilled to 2,000 m and encountered 10 m of net oil pay. A 3D seismic survey has been extended to cover a further 247 sq km, and the Weatherford 804 rig will drill the Kodos-1 in the neighboring Kerio basin.

The Amosing-2 well on Block 10BB, the first appraisal well in Amosing field, was drilled from the Amosing-1 (OGJ Online, Mar. 28, 2014) well pad. Tullow said it deviated 1,350 m northeast and downdip from the discovery well and encountered up to 30 m of net oil pay.

The well was sidetracked back to 400 m from the discovery well to provide additional insight into reservoir distribution. The 2A sidetrack encountered as much as 90 m of net oil pay. The Sakson PR5 rig drilled Amosing-2 to 2,878 m and Amosing-2A to 2,165 m. The rig will next explore the southern extent of the South Lokichar basin with the Ekosowan-1 well, 11.9 km southeast of Amosing-1.

“Etom-1 has successfully extended the South Lokichar rift bounding fault play northwards and we look forward to testing the southern area of the basin with Ekosowan-1,” said Angus McCoss, exploration director.

In addition, Tullow said the Ngamia-3 well on Block 10BB was drilled 1.6 km north of the Ngamia-1 discovery (OGJ Online, Apr. 15, 2013) and encountered 150 m of net oil pay. The Marriott PR-46 drilled Ngamia-3 to 2,700 m. The rig will drill the Ngamia-4 and Ngamia-5 wells.

Also, the SMP-5 testing/workover rig completed testing of the Ewoi-1 well (OGJ Online, Dec. 9, 2013), with flow rates of 50 b/d. The rig is now testing the Twiga South-2A appraisal well.

Tullow, the operator, has 50% and Africa Oil Corp. has 50%.
