currently needs investment and state-of-the-art technology. Iran has offered
Dey and Sefid Zakhour for investment.
Zakhour anticline is located north of the Dey anticline, 150 kilometers
southwest of the southern city of Shiraz.
Dey and Sefid
Zakhour are estimated to hold 6.2 tcf and 6.5 tcf of gas in place, respectively.
The two fields were discovered in 2005 and were said to contain a 11.4 tcf of
gas. With a recovery rate of 75%, 8.5 tcf of gas may be extracted from them.
In order to
complete exploration data in this field, 2D seismic testing was conducted in
2003 and the results were analyzed and interpreted. The Sefid Zakhour anticline
was said to have potential for production. Drilling operations started and the
first exploration well was spudded at a depth of 5,271 meters.
directorate of the National Iranian Oil Company (NIOC) explored sweet gas in
different layers of Kangan Dalan.
is estimated to hold 205 million barrels of condensate in place with a recovery
rate of 35%.
the NIOC Exploration Directorate forecasts, if 17 wells are drilled 30 mcm/d of
gas may be recovered.
The Sefid Zakhour
anticline is located around 30 kilometers south of the city of Qir.
development of Dey and Sefid Zakhour fields in Fars Province is expected to
provide 15.1 mcm of gas and 10,000 barrels of condensate.
equipment, stream pipelines, green space and processing unit are envisaged in
the development projects.
of a center for gathering and separation, laying out pipelines, installations
for Farashband processing unit and drilling projects are among activities
considered for this project.
objective sought by these projects is to develop the Farashband refinery to
create a gas processing capacity of 21 mcm/d. The refinery processing capacity
is planned to increase 5 mcm/d, while the produced gas would be injected into
the Iran Gas Trunkline 2 (IGAT2). Meantime, gas condensate will be transferred
to the Shiraz refinery.
A refinery is
envisaged for the two fields in two phases under engineering, procurement,
construction (EPC) framework. Phase 1 is already complete and Phase 2 is under
land for laying out pipelines and drilling wells, completing the existing two
wells, drilling and completion of 11 new fields, purchase of commodities and
activating wellhead installations, laying out wellhead pipelines, setting up a
gas and condensate separation center, installation of two pumps to transfer
condensate from Sefid Zakhour, purchase and installation of pigging system,
installation of line break valves, establishment of logistics camps, power
supply, acquisition of land for the refinery, development of Farashband
refinery including dehydration and gas condensate stability units, hydrocarbon
dew point regulation unit, low-pressure gas recovery compressors, and
installation of pumps to carry liquids from the refinery to Taheri Port are
among the most important equipment needed in the upstream and downstream
sectors of this project.
initial estimates, Dey and Sefid Zakhour would need IRR 8615.4 billion plus
$519.5 million in investment.
the decline in the flow of feedstock into Fajr Jam refinery and the plan to get
feedstock from neighboring fields, delivery of gas produced in Sefid Zakhour to
Fajr Jam refinery is among the most important plans for domestic gas supply.
