Tullow provides local oil and gas update
28 August 2014, 19:00
Nairobi - Tullow Oil announced the successful results from a series of exploration, appraisal and testing activities conducted in Blocks 10BB and 13T onshore Kenya.
The company said the Etom-1 well in Block 13T encountered approximately 10 metres of net oil pay, extending the proven oil basin significantly northwards.
Based on this result the ongoing 550 square km 3D seismic survey in the South Lokichar basin has been extended to cover a further 247square km in this northern area, including several similar prospects which are scheduled to be drilled in 2015.
The Weatherford 804 rig drilled the Etom-1 well to a final depth of 2,000 metres. The well will be suspended for use in future appraisal and development operations, following which the rig will move to drill the Kodos-1 well in September 2014 to test the first of several prospects identified in the neighbouring Kerio Basin.
Tullow said the Amosing-2 well in Block 10BB is the first appraisal well on the Amosing field discovered in January 2014, and was drilled from the Amosing-1 well pad.
The well was deviated 1 350 metres towards the northeast and downdip from the discovery well to calibrate the oil-water contacts of the several oil pools identified in Amosing-1.
The Amosing-2 well encountered up to 30 metres net oil pay.
As planned, the well was then sidetracked back to some 400 metres from the discovery well to provide additional insight into reservoir distribution in the area and for use in interference testing, planned to start later in 2014.
The Amosing-2A sidetrack encountered up to 90 metres net oil pay in several oil pools.
The Sakson PR5 rig drilled Amosing-2 to a final depth of 2 878 metres and the Amosing-2A sidetrack to a final depth of 2 165 metres.
The rig will now be moved to explore the southern extent of the South Lokichar basin to drill the Ekosowan-1 well in September 2014, 11.9 km south east of the Amosing-1 well.
According to Tullow, the Ngamia-3 well in Block 10BB continued the appraisal of the Ngamia field.
The well was successfully drilled 1,6 km north of the Ngamia-1 discovery well and encountered 150 metres of net oil pay in both Auwerwer and Lokone reservoirs.
The well has been suspended for likely use in future interference testing, appraisal and development activities.
The Marriott PR46 rig drilled Ngamia-3 to a final depth of 2,700 metres. The rig will now be moved to continue the appraisal of the Ngamia field, drilling the Ngamia-4 and Ngamia-5 wells which are planned to be used in an interference testing programme in the Ngamia field.
The SMP-105 testing/workover rig recently completed testing activities at the Ewoi-1 well.
Commenting today, Angus McCoss, Exploration Director, said, "Continued success in appraisal of the Ngamia and Amosing fields reinforces our belief that the South Lokichar basin holds very considerable potential which we hope to replicate in additional basins."
He said the next basin-opening test will be in the neighbouring Kerio Basin, with the Kodos-1 well expected to spud in early September.
