Improve subsurface understanding for CCS projects

Page last modified
October 31 2023

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.

Optiq solutions can 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.

CCS Case Study

Pro/con

Optiq solutions can be seamlessly integrated with any existing fiber-optic infrastructure
For temporary fiber-optic deployments, we have engineered and manufactured innovative fiber-optic coiled tubing, wireline, and slickline conveyances
Improves efficiency of borehole seismic acquisition by eliminating the need for a dedicated seismic descent, reducing costs and acquisitions time, therefore significantly lowering energy consumption and carbon emissions
Good-quality Vertical Seismic Profile (VSP) from either single- or multimode fiber
The large volume of data produced with fiber optics can be challenging to manage and may require specific expertise
