Sterling Energy 'disappointed' with Iraqi
UK-listed Sterling Resources has wrapped up a flow
test on the Sangaw North-1 well, in the Kurdistan
autonomous region of Iraq, but has been left
“disappointed” with the results.
The test was carried out over the open hole section
of the well between 3338 metres and 4190 metres
which contained target horizons in the Jurassic Mus
and Butmah formations and the Triassic Kurra Chine
Sterling said the well flowed at a stabilised rate
of about 4.6 million cubic feet of gas per day and
7280 barrels of formation water per day over a 12
hour period through a 1.5 inch choke.
It added that about 74% of the produced gas was
hydrocarbon gas with the remainder made up of 24%
hydrogen sulphide and 2% carbon dioxide.
"We are disappointed that the
open hole flow test has not demonstrated commercial
hydrocarbon flow rates within the deeper horizons of
the Sangaw North-1 well,” Sterling chief executive
Angus MacAskill said.
“The data acquired during this test will be
integrated with all the other data acquired in well
operations to determine the potential of these
Sterling attempted to carry out wireline logging
operations to identify the contribution from
individual zones within the open hole section but
was unsuccessful due to mechanical restrictions
within the flow testing equipment.
The company will now carry out a cased hole flow
test across a 100 metre interval within the Jurassic
aged Sargelu formation followed by another test
across a 100 metre interval within the Cretaceous
aged Kometan formation.
