Monitoring

Qteq Monitoring Systems develops, sources and advances a diverse portfolio of point and distributed sensor technologies that can be deployed subsurface to provide continuous, real-time visibility to georesource development and production, verify integrity of boreholes and wells penetrating and surrounding georesource deposits, and diagnose the performance and health of subsurface equipment used to extract georesources.

These surveillance systems are available in a variety of architectures, can be deployed on casing, pipe, micro-coil or armoured cable, with measurements transmitted to surface using a variety of wired and wireless techniques.

We focus on platform technologies that can be scaled to meet high volume demand, and supplied at an appropriate price point. The main technology platforms include:

  • Single end-point downhole pressure and temperature monitoring

  • Multi-zone downhole pressure and temperature monitoring

  • Optical distributed temperature sensing

  • Optical distributed acoustic sensing

  • Low-flow bladder pump sampling system

  • Wellbore and borehole fluid level monitoring

  • Wireless electromagnetic downhole telemetry

 

Access to continuous real-time in-situ data is vital to accelerating decision-making processes, inform workflows and shape a wide range of georesource development and production strategies, but these solutions must be:

  • Engineered to deliver the right type of data, at the required update rate, and with appropriate accuracy, sensitivity, repeatability and resolution

  • Designed to withstand the in-situ environment

  • Available in high volumes and short lead times

  • Installed in a safe, time efficient manner

 

Qteq has addressed each of these requirements. To date, Qteq has installed 5000+ downhole pressure monitoring systems in Australia since 2011, with time-efficient and right-first-time installation success achieved through a relentless focus on personnel safety and operational excellence.

Application of dedicated technical excellence ensures our downhole sensor and sampling systems are suited for the in-situ environment and aligned with your monitoring objectives.

Qteq recognises that achieving superior technical and operational excellence requires a rigorous staff selection process and extensive competency training. Our formalized Operational Process Management System (OPMS) fully integrates all key processes and an extensive library of underlying procedures, supporting work instructions and forms, to guide design, planning and installation of all permanent downhole monitoring systems. OPMS is aimed at ensuring technical and operational excellence is maintained on every installation project.
