Autonomous Turboelectric Generation Unit
Using Pressure Differential for Remote Wells

Description, Purpose, and Application:

Designed for autonomous power generation at remote gas or gas-condensate well clusters. Energy is generated using a small (1-2%) pressure differential between the gas pressure at the wellhead and the manifold pressure.

Application Experience:

▸ Unit being manufactured for pilot testing at Gazpromneft Zapolyarye
▸ Winner of the INDUSTRIX Accelerator by Gazpromneft JSC
▸ Identified 37 implementation sites at Gazpromneft and NOVATEK facilities

Advantages:

▸ Utilization of excess reservoir energy
▸ Absolute environmental friendliness
▸ Reliable and stable energy generation
▸ High efficiency and sufficient power output
▸ No radioactive elements
