3D seismic and VSP on intervention fibre optic cables
Silixa’s fibre optic intervention-based DAS seismic services offer a fast, reliable and cost-effective way to acquiring high resolution borehole seismic.
Applications:
Reservoir imaging
Vertical Seismic Profiling (VSP)
Time-lapse monitoring, 4D VSP
Delivering real-time imaging of the reservoir on single-mode, multimode or Constellation™fibres enables efficient decision making and improves ultimate recovery.
Our fiber intervention-based seismic services offer a rapid and cost-effective way of imaging the subsurface, delivering actionable insight into the reservoir.
The distributed nature of the measurement means that each point along the fibre is sampled simultaneously for each source initiation, dramatically reducing the operating time required for a conventional survey and significantly increasing the achievable wellbore coverage for moving source surveys.
High-resolution data enables cost-effective reservoir characterisation
- Inherently reliable downhole sensor array
- Low-cost approach to high volume seismic acquisition
- Full wellbore coverage for every seismic shot
- The highest spatial resolution and best sampling
More data in less time for actionable insight into the reservoir
The distributed nature of the measurement means that each point along the fibre is sampled simultaneously for each source initiation. This significantly reduces the operating time and increases the achievable wellbore coverage.
Data acquisition with a significantly smaller environmental footprint
Given the systems’ high sensitivity, a much smaller source of energy is required on site. This translates as faster results with a smaller equipment footprint and reduced emissions.
Silixa’s iDAS and Carina Sensing System deliver the highest fidelity data with a significantly improved signal-to-noise ratio, hence providing complete clarity in reservoir imagining and characterization.
Using our proprietary SeiBer™ acquisition software, DAS interrogators can be used to trigger the source using a conventional controller, alternatively, they can passively record the acoustic field continuously.
In passive mode, the DAS interrogator performs in a sample-perfect manner ensuring zero data loss during transitions. Multi-well acquisitions are made possible by synchronising multiple DAS systems.
Whether performing active or passive seismic acquisition, Silixa’s DAS seismic platforms can generate SEGY data files on-site integrating well geometry, source navigation, and time information.
