Mahogany adds shine to Jubilee

UK-based Tullow Oil said the Mahogany-2 appraisal well had struck oil off
Ghana, further boosting the size of the giant Jubilee discovery.
Tullow said in a statement today that the well had struck a “significant”
column of oil, and evidence from drilling, logging and reservoir samples
suggest the pay is part of one continuous reservoir stretching at least 11
kilometres to the Hyedua-1 find on the neighbouring deep-water Tano licence
and including the Mahogany-1 discover well.
The Mahogany-2 well, on the West Cape Three Points licence, is the first
appraisal well drilled on the field. The well struck net hydrocarbon pay of
50 metres in 63 metres of stacked reservoir sandstones over a gross interval
of 243 metres in the Turonian turbidite sandstone, the company said.
The well was drilled to total depth of 3443 metres by the drillship Songa
Saturn.
“The confirmation that Mahogany-2 is in communication with both Mahogany-1 and
Hyedua-1, reinforces our interpretation that Jubilee is a major discovery
and is likely to lead to a material upgrade of current resource estimates,”
said Tullow chief executive Aidan Heavey.
“We will continue our appraisal and development programme over the remainder
of 2008 with the overall objective of achieving first production in 2010,”
he said.
Tullow said limited flow tests would be carried out on Mahogany-2 to check
production potential and take further oil samples for analysis.
Three further appraisals are planned at Jubilee this year, to be drilled by
the semi-submersible rig Blackford Dolphin. The next, Hyedue-2, will be
spudded on the Tano licence in July.
Tullow has a 22.9% interest in the West Cape Three Points Licence, along with
operator Kosmos Energy (30.8755), Anadarko Petroleum (30.875%), the E.O
Group (3.5%) and Sabre Oil & Gas (1.854%). Ghana National Petroleum
Corporation holds a 10% carried interest.
Tullow also holds a 49.95% interest in the Tano licence and it’s the unit
operator of the Jubilee field.
