Maersk Oil operates two oil fields onshore Kazakhstan and will soon embark on a large field development plan that will involve the drilling of almost 200 new wells, subject to authorities' approval. Oil production is currently at some 9,000 barrels per day.

Maersk Oil acquired a 60% interest and operatorship of the Dunga field in 2002 with Partex and Oman Oil holding a 20% interest each. The 281 square kilometre onshore block is located about 50 kilometres north of Aktau in western Kazakhstan. It is operated under a Production Sharing Contract signed in 1994.

In 2000, Maersk Oil was granted the operatorship and 60% of the Saigak field with Arawak (40%) as partner. The field was developed and brought on stream in 2002. In 2010, it was sold, now subject to authority approval.
