Natural gas field was discovered near the town of Knezha. Proven reserves are currently 14.49 million cubic meters of natural gas and 5176 cubic meters of condensate, Exploration and production of oil and gas said.

Possible fields are estimated at 165 million cubic meters and potential - 764 million cubic meters. Thus total reserves that could be extracted from the Iskar –West deposit are estimated at 945 million cubic meters of gas and 393 thousand cubic meters condensate.

Condensate is light oil and almost ready gasoline. Studies began 1.5 years ago and the project is to connect it to highway pipeline from Bhutan to Dolni Dubnik, said the mayor of Knezha - Simeon Sharabanski.

5 years ago gas and condensate were found at 4100 m near the Pleven village Deventsi. Specialists then announced that the potential resource was about 6 billion cubic meters.
