Muradkhanli is the largest and most productive of Zenith’s three contingent fields. It is located in the Aran region of Azerbaijan, 30 kilometers south from the town of Kurdamir and 250 kilometres inland from Azerbaijan’s capital Baku.
Lake Sarisu and marshlands occupy the south-western part of the field. Geologically, the Muradkhanli field is located in the vast, hydrocarbon prolific Lower Kura Basin from which oil production has taken place for the past 150 years.
Drilling activities in Muradkhabnli first began in 1968 following its discovery through a series of gravity, magnetic and seismic exploration surveys performed in 1965. Commercial oil production was achieved from the fractured Upper Cretaceous volcanic reservoir in 1971. High rates of production were almost immediately observed supported by natural reservoir pressure at a series of highly productive wells. Oil was also discovered in the sedimentary Eocene section in 1973 and production from this interval began in 1975. Two additional smaller reservoirs in the Oliogocene and Miocene reservoir were discovered in 1980 at depths between 2,700 and 3,400 metres. Previous drilling into the Middle Eocene interval has evidenced that a very significant amount of oil remains in place.
In 1978, the Muradkhanli field reached a peak production of 10,000 barrels of oil per day, almost all of which was produced from the Upper Cretaceous interval.
Wells such as M-221, drilled in 1981, initially produced in excess of 2000 bopd. In 1999, this well was producing at a rate of 1400 bopd before production fell to 50 bopd due to a series of structural failures in the well.
The Muradkhanli field presents excellent drilling and well workover opportunities due to its very significant historical productivity, low production decline rates, and the significant undeveloped areas of the field.
The field has a full range of production, logistical and processing facilities, including an infield gathering system, storage tanks, field office, as well as processing and loading infrastructure.
