LONDON (Alliance News) - Tullow Oil PLC on Tuesday said it has encountered a net oil pay at the Etom-2 well in northern Kenya and said its Ngamia well in the country has produced thousands of barrels of oil per day under test conditions.
The FTSE 250-listed oil producer said the Etom-2 well on Block 13T encountered 102 metres of net oil pay in two columns after being drilled to a total depth of 1,655 metres.
"The objective of the well was to explore the Etom structure in an untested fault block identified by recent 3D seismic. Oil samples, sidewall cores and wire line logging all indicate the presence of high API oil in the best quality reservoir encountered in the South Lokichar Basin to date," said Tullow.
Angus McCoss, exploration director, said: "We are delighted with the Etom-2 well which encountered over 100 metres of net oil play in the best reservoirs in the basin so far. Discovering this thick interval of high quality oil reservoirs further underpins our development options and resource base."
The company also identified the potential for more prospectivity in the northern part of the basin, which hosts to Erut and Elim prospects. They will be considered as part of future exploration programmes going forward.
"This result also suggests significant potential in this under-explored part of the block as it is the most northerly well we have drilled in South Lokichar and is located close to the axis of the basin away from the basin-bounding fault. Accordingly, we will review the potential of the greater Etom area and neighbouring prospects to decide on our forward programme," said McCoss.
The rig used to drill the Etom-2 well will now be moved to Block 12A to drill the Cheptuket-1 well toward the end of 2015. That will be the first of two wells to be drilled in the Kerio Valley basin, the company said.
In addition, Tullow has completed the extended well test on the Ngamia-8 well in Block 10BB, also in Kenya. The well produced a total of 38,000 barrels of oil under test conditions, averaging 2,400 barrels of oil per day from five completed zones, with all the zones apart from the lowest one producing oil naturally, it said.
Tullow operates Blocks 13T and 10BB with a 50% stake alongside its partner Africa Oil Corp, which holds the other 50%.
