Extra bounty from Didon pilot probe
Swedish player PA Resources said a pilot hole drilled as part of the
development of new production wells on the Didon field off Tunisia has
proved a larger oil column than expected.
PA added the pilot well confirmed excellent reservoir properties.
"It is still too early to make any comments on the reserves implications,
however the results are encouraging for our continued efforts to enhance the
oil recovery from Didon, and the well will contribute significantly to the
total field production," PA boss Ulrik Jansson said.
The pilot hole was drilled by the Ensco 85 jack-up rig from the Didon
platform, in the Gulf of Gabes, to a reservoir in the central sector of the
Didon field. It was drilled to gather information on oil saturation and
pressure across the reservoir section and serve as control for the drilling
of the Didon-7 horizontal production drain.
PA said the reservoir section came in higher than prognosis and the data
gathered in the pilot hole has proven a larger than expected vertical oil
column and confirmed the excellent reservoir quality expected in the area.
The pilot well used the first section of the Didon-8 pilot well, which hit a
fault when it was drilled.
The pilot hole section will now be plugged before the horizontal production
drain of the Didon-7 will be drilled. The horizontal drain will be about 550
metres long and will be placed along the top of the reservoir section.
Once completed, Didon-7 well is expected to increase production significantly.
Following the drilling and completion of Didon-7, PA will start drilling of a
second production well targeting the western part of the field.
PA holds 100% of the Didon licence.
