A New Era of Borehole Seismic Measurements
Optiq Seismic fiber-optic borehole seismic solution

Borehole seismic data bridges the gap between surface seismic and downhole measurement to delineate your reservoir properties. However, the opportunity to acquire borehole seismic data was often missed in the past. Traditionally, borehole seismic data has been acquired using wireline-deployed complex geophone arrays. This presents multiple challenges including increased risk of failure and fishing, large operational footprint, and low operating efficiency.

You can now address those challenges with the Optiq Seismic fiber-optic borehole seismic solution. You can acquire zero-offset, offset, walkaway, 3D and 4D, walkaround, and vertical incident seismic profiles using the Optiq Seismic solution. It is now possible to acquire borehole seismic data in combination with any wireline descent or transparent to production operations with permanently installed fiber. Removing the geophone array from borehole seismic acquisition results in streamlined logistics, up to 99% improvement in operational efficiency, lower carbon emissions, and reduced operational risk.

Data is good, but insights are better. By combining AI, machine learning, edge processing, and cloud-native capabilities, our digital workflows deliver intelligent job planning, predictable execution, and faster answers—enabling you to make better decisions. Don’t avoid borehole seismic operations due to historical challenges: Harness the power of light to better understand your reservoir.

Now, image a scenario offshore where you have an underperforming well, and there's uncertainty around the well positioning.  You only have 5 months to decide whether to sidetrack or redrill the well to improve production. High-resolution structural imaging with a multiwell 3D VSP survey is the only way to make a high-confidence decision. Adding to the complexity, shutting in the wells for data acquisition is not an option, eliminating conventional borehole seismic as a solution. In this exact situation, by deploying the Optiq Seismic solution on permanently installed fiber optics, clamped to the production tubing, Schlumberger reduced the acquisition time from 100 days to 12 days compared with conventional geophones—saving an estimated 7,500 metric tons of CO2e emissions. This also avoided any deferred production. Using our workflows, the production noise was successfully filtered from the borehole seismic data. We delivered high-resolution 3D images 3× faster than the industry standard.

With more than 70 operations and 4,000 hours of rig time saved, we have achieved many industry firsts around the globe to significantly reduce carbon emissions. As we illuminate a new path for borehole seismic acquisition in the energy industry, we would like to welcome you to the new era of borehole seismic capabilities.

Reduce your risk. Improve reservoir understanding. And drive sustainability and performance though operational efficiency. Join us for the brighter future of energy.
