Underground gas storages

UGS (underground gas storage facilities) substantially contribute to security of customers supply with natural gas. They allow to create a stock of gas to meet peak gas demand during the winter.

Natural underground reservoirs are adapted for underground storage of gas with a depth of 1000 meters or more. Geologists find suitable cavities filled with water. Hundreds of small holes are drilled. Then, gas with a pressure of 120 atmospheres is applied to push the water away.

The company has extensive experience in complex reconstruction and modernization of the key elements of the UGS facilities.

Being a natural gas transit country, UGS are hihly important for Ukraine and for transported gas end-users. Ukraine has a number of gas storage facilities, including the largest in Europe — “Bilche-Volitsko-Uherske” UGS.

Our experience encompasses all aspects of modernization and reconstruction:

  • equipment of storage facilities;
  • separation and connection of gas wells to the facility;
  • pipelines for inhibitors;
  • partial or complete reconstruction and modernization of the booster station (BS);
  • reconstruction and modernization of technological platforms of gas gathering, auxiliary buildings and structures.

Achieving the level of maximum productivity (gas drying units), replacement of regeneration blocks and modernization of the absorbers are our important technological priorities.

Our priorities are maximizing of dryer units efficiency, regeneration and absorbing units modernization, reliability and high-tech potential are foundational for our automation and process control. High automation level allows to have high operational reliability. All-to-be-reconstructed units are equipped with the latest sensors and transducers.

The efficiency of natural gas drying has been considerably increased with the use of new diethylene glycol (DEG) regeneration units. Also the number of such units can be decreased. For example, for “Bilche-Volitsko-Uherske” UGS reconstruction project their number has been decreased from 11 to 5.

In general, our priorities are rationality of production and construction, efficient use of the resources and advanced technology.
