Harness the power of light for multidomain measurements in a fraction of the time
The use of fiber-optic sensing and its capabilities are being maximized now more than ever within the energy industry. Traditional measurements typically rely on discrete sensors that measure at certain points, whereas distributed sensing technology uses fiber-optic strands as the sensor. This enables continuous, real-time measurements to be captured along the entire length of a fiber-optic strand.
Optiq fiber-optic solutions cover distributed acoustic sensing (DAS), distributed temperature sensing (DTS), distributed temperature gradient sensing (DTGS), and distributed strain and temperature sensing (DSTS) systems for a wide range of applications across energy industries—including oil and gas, carbon capture and sequestration (CCS), geothermal energy production, and mining.

Oil and Gas
Fiber optics in upstream oil and gas applications
Industry-unique Optiq solutions are used for many applications in upstream oil and gas and can be easily integrated with our nonfiber-optic comprehensive measurements, products, and services for rich, evergreen insights. These microsolutions include the following:
Borehole seismic data acquisition—For reservoir delineation and field development optimization, a reservoir engineer can now integrate borehole seismic data into their evergreen reservoir model using Optiq Seismic fiber-optic borehole seismic solution across the life cycle of the field. The deployment-agnostic Optiq Seismic solution acquires zero-offset, walkaway, 3D seismic, 4D reservoir monitoring, and many more vertical seismic profiles (VSPs) with 1.5-m spatial resolution—and in minutes rather than the hours or days required using conventional methods.
Induced seismicity monitoring—Monitor regulatory compliance or track seismic events using temporarily or permanently deployed fiber optics. With a real-time, automated traffic alert system, enabled by Seismic Focal Point real-time induced seismicity monitoring service, never miss an event alert again.
Well integrity assessment—We don’t just stop at locating the leak in your completions. We have the ability to understand the cause and remediate accordingly by combining high- and low-frequency fiber-optic data with our wireline ultrasonic, spectroscopy, and caliper corrosion measurements.
Production monitoring—Understanding production and production interference is critical to maintaining an accurate evergreen reservoir model. Using either temporarily or permanently deployed fiber optics enables you to understand production in the time domain across the full reservoir. Optiq solutions can be used as robust stand-alone production monitoring solutions in combination with production logging tools for increased confidence in your reservoir performance.
Injection monitoring—Understanding injection across your reservoir is a foundational step in predicting the production for unconventional plays. Uniform injection can also be critical for the performance and economics of CCS, geothermal, and saltwater disposal projects. You can also use fiber optics to monitor out-of-zone injection (OOZI) to verify caprock integrity and identify whether new fractures are created during injection. Optiq solutions enable a common experience across all your injection monitoring projects.
Stimulation effectiveness monitoring—With Optiq StreamLINE polymer-locked fiber-optic wireline conveyance, it is now possible to measure cluster efficiency in the treatment well and strain in an observation well with a simplified operation and smaller pressure equipment footprint. This is a cost-efficient solution that does not depend on permanent fiber-optic installation in your unconventional wells.
Flowback monitoring and more—Flowback monitoring can be the first indication of reservoir performance after stimulation and provides important inputs to validate stimulation models and success. For coiled-tubing-, wireline-, and permanently deployed fiber optics, it is now possible to have the fiber in the well during regular hydraulic fracturing and matrix acidizing while continuing to monitor the flowback immediately after stimulation. Having flowback insights in relevant time can assist in optimizing field development.
Fiber optics in midstream oil and gas applications
In the midstream sector, Optiq solutions act as a remote oil and gas pipeline integrity monitoring system, providing real-time leak detection, pig tracking, and perimeter intrusion. In addition, we apply machine learning and AI to improve confidence in threat detection and decipher activities along your assets.
Pipeline integrity monitoringCCS
Fiber optics in CCS applications
Optiq solutions can also be used to improve subsurface understanding for CCS projects. These solutions can assess carbon storage capacity; monitor the position of CO2 plume or seismicity for regulatory compliance; and evaluate CO2 injection profiling, well injection containment, and well integrity.
Geothermal
Fiber optics in geothermal applications
For geothermal energy production, Optiq solutions enable various applications, including
- reservoir structure mapping
- induced seismicity monitoring
- geothermal production optimization
- well integrity evaluation
- injection monitoring to optimize the injection performance and maximize geothermal heating of the injected fluids.
Mining
Fiber optics in mining applications
Optiq solutions can be utilized to monitor seismicity during mining operations and provide real-time alerts to ensure safety performance and regulatory compliance. Additionally, Optiq Seismic solution can be utilized to map the subsurface structure and locate veins of interest to plan mining operations.
