Tethys Petroleum Limited ("Tethys" or the "Company") (TSX: TPL)(LSE: TPL)
today gave an update on its operations in the Republic of Tajikistan.
Testing operations are underway on the East Olimtoi EOL09 exploration well
located south of the town of Kulob some 10 km north of the Afghan border. This
well reached a total depth of 3,765 metres in the Akdzhar formation and testing
operations are being undertaken on the overlying Bukhara and Alai formations.
Currently the well is flowing a mixture of completion brine and oil from
the upper Alai sandstone interval, this oil being of good quality with an
API gravity of approximately 36 degrees. The current section open to testing
includes this upper Alai sandstone unit as well as the lower Alai limestone
interval and the upper part of the Bukhara formation. The well was drilled
with heavy drilling fluid (weighted with barite), which was required
to control the well when it intersected the upper Alai reservoir. Barite
is currently being observed in the flow lines which the company believes
is also inhibiting flow at present. It is anticipated that the well will
clean up in due course, however the cleanup period may take some time.
The Company is currently evaluating methods of speeding up the clean up
of this well including acidisation or nitrogen-lifting using coiled tubing,
subject to availability of equipment.
