Enabling cost-effective sweep efficiency
To eliminate this risk, OptaSense provides a low-cost alternative that enables higher quality seismic surveys at more frequent intervals.
For Deepwater Imaging,
Borehole seismic makes economic sense
Borehole seismic delivers more value
To meet effectively attain these benefits, OptaSense recommends running their DAS-VSP borehole seismic acquisition service, capable of acquiring 2D, 3D and 4D VSP data, and the fourth generation ODH-4 DAS interrogator unit (IU) for its unmatched imaging and measurement performance. The ODH-4 provides a 6 dB improvement in signal-to-noise ratio over its predecessor—delivering the highest fidelity VSP measurements available.
In addition to higher quality seismic imaging, the ODH-4 offers increased sensitivity, finer spatial sampling (1.02m) and finer spatial resolution of (4.02m gauge length) to capture high-caliber image resolution.

Multimode Fiber Acquisition
single-mode fibers, most legacy fiber optic installations are multimode. By continuously pioneering the evolution of DAS technology, OptaSense has proven quality DAS measurement can be acquired on either single-mode or multimode fiber—enabling on-demand acquisition of quality seismic surveys from wellbores with existing fiber.
