Upstream - Downhole and wells

Omnisens DITEST fiber optic technique provides monitoring solutions to the upstream oil & gas industry where distributed pressure, temperature and strain monitoring brings added value to the oil extraction and operation.

downhole and wells distributed temperature monitoring

As the worldwide oil reserve is decreasing, exploitation of difficult reservoirs has developed rapidely. Compared to standard wells, the production of these reservoirs requires complex and high performance instrumentation such as fiber optic distributed pressure, distriburted temperature and distributed strain monitoring.

Omnisens solutions offer unrivalled performance in downhole and wells operation monitoring.
Compared to other technologies, the DITEST Brillouin-based interogators provide the following advantages in downhole distributed temperature and strain monitoring:

  • Insensitivity to hydrogen darkening
  • HIgh temperature resolution
  • High strain resolution
  • Very large optical budget and dynamic range
  • Calibration insensitive to varying attenuation and losses
  • Distributed pressure monitoring

Omnisens approach in downhole monitoring

The applications range from the detection of gas and steam breakthrough in production wells, integrity monitoring of well casing, enhanced operation of thermal wells, water injection control and optimization, flow and pressure monitoring.
