Downhole Gas Compressor Programme (DGC)
Downhole Gas Compressor Programme (DGC)
Partner: Eni S.p.A., one of the largest oil and gas exploration companies in the world.
Project: Downhole gas compression can extend the lifecycle of declining wells and improve gas well production. Use of our patented core technologies allows us to design a compact and intelligent compression solution that sits within a seven-inch pipe several thousands of metres below the earth’s surface. After a comprehensive testing and development cycle in the UK, field testing of the DGC will allow Corac to prove its technology in a demanding operational environment. By hosting our DGC in one of its declining wells, Eni is contributing to significant innovation in this field.
The key features of the downhole gas compressor for this project include:
- Gas filled brushless permanent magnet motors
- DC electrical transmission to downhole power electronics
- Driver and compressor on one piece shaft
- Gas bearing technology
- Low speed blading
- Seal-less systems
- Low maintenance design
- Oil-free compressors
