New Oil Deposits Discovered at Uzen Field

31.01.2022

New oil deposits have been discovered at the Uzen field in the Mangistau region through additional exploration. As a result, recoverable oil reserves have increased by 39.9 million tonnes.

The increase in hydrocarbon reserves will have a significant impact on the economic performance of JSC NC “KazMunayGas”.

In 2017, a team of geologists from JSC NC “KazMunayGas”, Ozenmunaigas JSC, KMG Engineering LLP and the Aktau Branch of KMG Engineering initiated a detailed programme of additional exploration of the Uzen field. A high-resolution 3D seismic survey (368 sq. km) was carried out, the entire well stock (more than 7,500 wells) was reinterpreted, the geological concept was revised and the geological 3D model was rebuilt during 2017–2021 under the program.

Following the work done, the field’s structure was detailed and new oil deposits were discovered. As a result, the oil reserves of the Uzen field increased by 8%, which equals 39.9 million tonnes of recoverable reserves.

The adjusted volumes of hydrocarbons were put on the books by the State Reserves Committee of the Republic of Kazakhstan at the end of 2021.

Currently, the field development project is being adjusted to take into account new reserves and plan to put them into production.

For reference:

Ozenmunaigas JSC is a 100% subsidiary of JSC NC “KazMunayGas”. In 2020, the company accounted for 6% in the oil and gas condensate production volume in Kazakhstan. Ozenmunaigas produces oil and gas condensate at the Uzen and Karamandybas fields in the Mangistau region.

Uzen is one of the largest fields with unique initial geological reserves not only in the Republic of Kazakhstan but all over the world. It is a multilayer field with a complex structure, where oil and gas reservoirs are concentrated in the terrigenous section of the Jurassic-Cretaceous deposits.
