Sumar is a newly discovered field,
but since it is shared with neighboring Iraq, the National Iranian Oil Company
(NIOC) has prioritized its development.
But when Iran decided to develop it,
its petroleum industry was under international sanctions and it had to award
the contract under an EPCF agreement to Iranian companies. The contract
envisaged drilling two wells, building stations for transmission and separation
of oil and gas, pumping and gathering systems. Production from Sumar was
initially expected to start two years after the start of operations with Phase
1 output at 5,000 b/d and Phase II output at 10,000 b/d, but this objective was
However, the Iranian Central Oil
Fields Company (IOFC), which administers Sumar, drilled one well which produced
3,000 b/d. The oil produced from this field is being carried via a 23-kilometer
pipeline to Naftshahr production/desalting unit.
In preliminary assessment report on
Sumar oil field in 2009 and 2010, development of the field in Asmari Formation
with an initial output of 5,000 b/d from four wells was envisaged.
In the study conducted for the
transfer of oil from Sumar oil field to Naftshahr production and desalting
unit, installation of multiphase pumps, and a single-phase transmission system
including a separator, pump and compressor fitted with OLGA and PIPESIM were
The preliminary studies indicated
that at most 5,000 b/d of pre-salt oil could be processed at Naftshahr
production and desalting unit. But as long as non-salt oil is being produced
the processing of the entire oil is possible in the old unit.
Drilling of three new vertical
fields in Asmari Formation, workover on an oil production well, installing a
25-kilometer offshore streamline stretching from wells to manifold, acquisition
of land and drilling of well, setting up manifold and two-phase separation
system, purchase and installation of single-phase pumping system with a
capacity of 10,000 b/d, 123 horsepower and 550 pam external pressure, laying
out 23-kilometer pipeline to carry 10,000 b/d of oil to Naftshahr production
and desalting unit, installing 48 kilometers of power supply lines and a 1.5MW
electricity station stretching from Naftshahr to satellite manifold and Sumar
wells are among the most important equipment and facilities needed for Phase 1.
After Iran signed a landmark nuclear
deal with the six world powers, Poland's PGNiG signed a memorandum of
cooperation with the Department for Development and Engineering Affairs of NIOC
in November 2016 to study Sumar. The CEO
of PGNiG said at the time that cooperation with the NIOC would clear the way
for more cooperation in oil extraction.
The Sumar recovery rate currently
stands at 15% and it holds light oil. Four new wells are expected to be drilled
in Sumar for a daily output of 4,500 b/d.
submitted the findings of its studies to the NIOC in December. The report has
been reviewed by the Committee of Advisors at the NIOC Directorate of
Reservoirs. A final decision is to be made on the development of Sumar, soon.
