Case Study Fiber Optics Improves Subsurface Understanding for a CCS Project
Optiq Seismic solution efficiently acquired data across four wells using both multimode and single-mode fiber.
Borehole Seismic
Enhancing reservoir characterization through borehole data
Collecting borehole data for reservoir characterization
Borehole seismic data collected during and after the drilling of exploration and appraisal wells delivers valuable information for reservoir characterization. Combined with surface seismic data, borehole seismic surveys can help calibrate results and improve your predictions, as well as image specific reservoir features around the borehole. Drillpipe-conveyed systems are used to collect information on seismic velocities while drilling and to predict lithological changes ahead of the bit. Wireline-conveyed tools and systems are used to acquire high-resolution seismic images in and beyond the borehole.
Many subsurface imaging problems cannot be solved without a 3D survey, and when a survey also needs to be performed in the borehole, the solution is 3D vertical seismic profile (VSP) technology. Our new Optiq Seismic fiber-optic borehole seismic solution reduces VSP acquisition time from the hours required by conventional seismic operations to just minutes.
Optiq Seismic fiber-optic borehole seismic solution acquires multiple VSP types, unlocking full field development planning—from reservoir definition, imaging, evaluation, and monitoring, as well as drilling solutions.
