CHIREN UNDERGROUND GAS STORAGE (UGS)

The Underground gas storage (UGS Chiren) has been established on the basis of the depleted gas condensate field Chiren found on 16.08.1963 by blowout of well P-3, attached to the homonymous thrust local structure. It is located about 20 km northwest of Vratsa with dimensions of 15/7 km.

By Decision No. 805 of the Council of Ministers dated 4.11.1963  the joint venture for oil and gas production - Pleven was founded, including "Oil and Gas" - Chiren. Chiren was established as gas production section to the joint venture "Oil and Gas" - Pleven on 01.01.1964.

By Decision No. 32/28.06.1966 of the Council of Ministers dated 08.01.1966, the joint venture "Oil and Gas" - Pleven was restructured and transferred for management by DSO "Neftohim". The newly established company functioned as DP "Oil and Gas" - Chiren having a business account and becoming self-supported as an individual legal entity.

During the period 1965 - 1967 the cement plant "Beli Izvor" was gasified, supplied by limited gas quantities extracted from the gas-condensate field Chiren.

The first gas quantities for the plant were supplied on 06.02.1965. The planned design production of the field was achieved in 1967, when its exploration was completed. That production continued until 1974.

In 1974 the construction of underground gas storage Chiren and the operation of the gas pipeline branches commenced: Batultsi - Chiren, Chiren - Cement Plant - Beli Iskar, Chiren - Chemical Plant - Vratsa, Chiren - Montana.

So far 43 operating cycles of the storage have been performed and the total injection amounts to 10.9 bcm and the withdrawal -  9,7 bcm.
