No significant shows for Tullow exploratory well in Kenya

Tullow Oil PLC, London, reported that its first well drilled in Kenya’s North Turkana basin did not find significant oil or gas shows.

The Engomo-1 exploration well, drilled west of Lake Turkana on Block 10BA, has been plugged after reaching 2,353 m.

Despite the lack of success, said Angus McCoss, Tullow exploration director, the company still has “a vast amount of undrilled acreage with identified prospects and leads providing significant remaining exploration potential (OGJ Online, Oct. 23, 2014).”

In the South Lokichar basin, Tullow’s activity includes preparation for extended well tests for its Amosing wells, beginning in mid-March. Amosing-1 and Amosing-2A were completed in five zones. Amosing-1 flowed at a combined maximum rate of 5,600 b/d from five zones, and Amosing-2A, 6,000 b/d from four zones. Pressure data shows connectivity between the wells in the upper three zones.

Also in South Lokichar, the Ngamia-7 appraisal well encountered up to 132 m of net oil pay in being drilled to 2,914 m to test the Ngamia field’s eastern flank. Static pressure data from the Ngamia-1, 3, 5, 6, and 7 wells supports connectivity at multiple reservoir horizons. Extended well tests at Ngamia are planned.

The company also said the Ekales-2 appraisal well is at 2,817 m and has encountered up to 70 m of potential net oil pay. McCoss said results to date from Ekales are “very encouraging.”
