Sărmășel gas field

[2] The gas produced at Sărmășel and in the surrounding area is considered to be the purest one; it consists of dry gases, usually made of 99% methane, with the rest being hydrocarbons (ethane, propane, and butane).

[11][12] Originally intended for the extraction of potassium salts, the discovery accessed one of the richest natural gas deposits in the world at that time.

[16] In 1914 the first gas pipeline was completed, spanning from Sărmășel to Turda to Ocna Mureș, with a length of 55 kilometres (34 miles) and 153 millimetres (6 in) diameter.

[12] In July 2016, a new compressor station was inaugurated at Sărmășel; the 238 million lei investment will increase storage capacity and the facility's capability to deliver gas at times of peak demand.

The upgrade seeks to increase the flexibility of the storage system, improve security of supply, and contribute to North-South gas interconnections in Central and Eastern Europe.
