Projects oil gasDistributed Pressure Sensing (DPS) of “Intelligent completions”

Intelligent completions incorporate permanent downhole sensors and surface-controlled downhole flow control valves. The technology enables monitoring, evaluating, and managing production in real time without any well interventions. Data are transmitted to surface for local or remote monitoring.

These completions:

  • provide real-time downhole monitoring of pressures and temperatures
  • enable surface-controlled production from each zone or lateral to optimize production and reservoir management
  • reduce production of undesirable water or gas
  • increase recovery and extend the economic life of the well
  • Allow production testing of individual zones without interventions and with minimal production interruption.

Intelligent completions proven their value through deployment in subsea wells, where intervention is expensive and high-risk, and has contributed in managing production from multilateral wells, horizontal wells with multiple zones, wells in heterogeneous reservoirs, and mature reservoirs.

Smart Fibres’ Fluid Contact Monitoring (FCM) system is the integral part of the completion. The over view of FCM system, key features and specification is available for download. More detailed overview to the technology of Permanent Downhole Distributed Pressure Sensing  with Fiber Bragg Grating Sensing Technology is available for review.

Through collaboration with leading Iranian Oil and Gas upstream services, Simeng is tendering for the next generation of Intelligent completions development in Iran.

projects renewable energyBlade Loads Monitoring System

Wind energy production is rapidly increasing to help satisfy growing global energy demands. In a push to reduce wind energy production costs, turbines are becoming larger and are often deployed offshore where wind speeds are higher. In this environment, high reliability and low maintenance is critical. However, the difference in wind speed at the top and bottom of the rotor span (wind shear) is greater. This leads to rotor imbalance which reduces the fatigue life of the main bearings and other drivetrain components. Individual pitch control (IPC) of the blades solves this issue by minimising fatigue loads, so extending life and reducing maintenance costs.

IPC algorithms require real-time loads data for each blade to be available at high speed. Measuring these loads with electronic sensors is impossible due to the frequency of lightning strikes to the blades. Blade load monitoring systems using optical fiber Bragg grating sensors have broad industry acceptance due to the technology’s insensitivity to lighting strike.  Smart Fibres’ optical blade loads monitoring system benefits from highly robust aerospace qualified instrumentation, a long and successful deployment history and a price point that meets industry needs. The Smart Fibres system also outputs blade bending moments that can be used for condition monitoring. The over view of IPC system, key features and specification is available for download.
