Imaging Around the Borehole

See farther into your reservoir and enhance characterization

Schlumberger borehole imaging experts can process seismic data to create a high-resolution image around the wellbore and often ahead of the bit. This can help you determine the structure and extent of your reservoir, the position of salt bodies, faults, bed boundaries, pinchouts, and more. This information can be critical if a sidetrack or assessment well is required.

Salt bodies can often cause undesirable effects that limit the resolution of surface seismic data. With a carefully designed borehole seismic survey, data quality can be improved below and adjacent to salt, leading to improved imaging of the reservoir and salt body.

Imaging between wells

In addition to single well imaging applications, we can provide crosswell imaging using either borehole seismic or deep-reading electromagnetic imaging to determine the applicability of these methods to you well spacing and reservoir conditions. We can assist in the survey design and analysis of data after acquisition for reservoir structure and fluid identification. Interpretation of these crosswell surveys can lead to better structural determination than surface seismic, determine the location of injected fluids, and detect bypassed pay.

Natural fracture identification and orientation

Walkaround (radial) borehole seismic surveys can be used to identify natural fracture density and fracture orientation near the wellbore.
