3. Introduction
• This field is located in
the desert of southeastern
Kuwait; Middle East
• Onshore oil field
• The world’s largest
sandstone oil field
• 29°06′39″N, 47°58′00″E
• ~750 Km2
4. History
• Discovered in 23, February, 1938
• Discovery was based partially on magnetics and
oil seeps.
• The second largest overall, after Ghawar
• In 1946, start of production (By KOC)
• Production with original pressure about 40 years
• Peak of oil production in 2005
5. • First of seawater injection was started in 1999.
• 1200 well were drilled since the field discovered
• 1991 - Iraqi soldiers set the Burgan Field on fire as
they retreated during the Iraq war. A total of 297 well
fires were extinguished
• An estimated 1.4 GBO was lost during the seven
month
• 2013 - Fourth most productive oilfield worldwide
6. • 2010 - Chief Executive of the Kuwait Oil
Company reported that Burgan produced half
of Kuwait’s oil.
• From 1948 through 2016 the Burgan
complex has produced 32.5 GBO.
• Its production costs are by far the lowest of
any oil field in the world.
7. Geology
• It include three producing
subfield
Burgan (500 Km2)
Magwa (180 Km2)
Ahmadi (140 Km2)
• These subfield base on
three structural dome
8. • This field lies within the
Arabian basin
• It is an anticline structure that
is 30 miles long.
• It has numerous faults (~250),
these may act seal to fluid
flow
• Magwa and Ahmadi are
separated from Burgan by a
central graben fault complex
• Producing horizons share
similar sub sea oil/water
contacts and their primary
drive mechanism is underlying
water.
10. • The Burgan to Mauddud interval represents an overall
transgressive sequence
• Wara and Burgan formation were deposited in a fluvial
deltaic environment on the continental shelf margin of the
ancient Tethys Ocean
• Both formations are separated by carbonate succession of
Mauddud Formation which deposited in a shallow marine
environment
• The Mauddud limestone reservoir with low permeability
from 1 to 50 md
11. • The Middle Third Burgan is the most prolific
reservoir from which more than 75% oil production.
• The middle third Burgan reservoir mainly consists of
multi-Darcy sand and with very strong aquifer
support.
• The Upper Third Burgan and Lower Third Burgan
reservoirs are of lower sand quality and poor sand
connectivity.
12. • The Lower Third Burgan acted as conduit in the past
for fluid migration from the fourth sand to Middle
Third Burgan.
• Burgan' formation containing 35% porosities and
permeability of over 400 millidarcies
• The Fourth Burgan reservoir is the lowest major
producing zone
13. • Shale layers that separate the Upper, Middle, and
Lower Third Burgan sands
• The hydrocarbon-bearing intervals are between 7,400
and 8,000 ft deep and are normally pressured.
• The total reservoir thickness is 1500 feet
• The reservoir temperature is 170ºF
• 4 to 15 barrels of oil per day/pounds per square inch.
14. • The initial reservoir pressure in the upper Burgan is
estimated to have been 3,855 pounds per square inch
gauge (psig)
• A single original oil/water contact (OWC) is reported,
there was vertical communication between different
reservoirs
18. • The 28-36⁰ API mature oil is produced from Wara
and Burgan Formation
• Oil gravity decreases with depth
• The sulfur content is approximately 2.5%.
• 1972 - 2,400,000 barrels per day
• 2005 - Production capacity: 1,700,000 barrels per day
19. • Current production – 1,200,000barrels per day for oil,
• 550 MMcf
• Estimated oil in place – 61 GBO
• Current producing formations Wara (K1)
20. The Burgan complex is expected to produce for the
next 30-35 years and ultimately recover 61GBO and
38Tcf gas.
22. Conclusion
• The world largest siliciclastic field and second largest field
• 3 main reservoir
• Current producing reservoir is Wara formation
• Water drive mechanism
• Type II Kerogen , oil and gas prone
• URR 61 GBO and 38 Tcfg
• 2.5% sulfur content
• 28 -36 API⁰
23. • 1,200,000b/d and 550 x106cu ft/d current
production
• Estimatily 35 GBO have been produced from
this field
• Except to produce for the next 24 – 30 years
