Seismic While Drilling (SWD)
seismicVISION seismic-while-drilling service delivers time-depth-velocity information in real time and does not disrupt drilling operations. It is the industry's only look-ahead technology that lets you make the best drilling decisions, reduce costs, and improve safety.
The system delivers traditional borehole seismic measurements, including real-time checkshot and interval velocity data, that reduce uncertainty ahead of the bit from several hundred feet—sometimes several thousand. Real-time waveforms can be sent on surface through a high-speed MWD telemetry system for quality control of downhole data. The real-time waveform resolution and sufficient length allows look-ahead vertical seismic profile (VSP) processing.
Continuous transmission of data through the InterACT monitoring and data delivery system allows data and consulting experts to provide data quality control, update the target locations, and process look-ahead VSPs while drilling.
With this improved navigation, you can
- update casing and coring points while drilling
- predict target depths in real time for trajectory adjustment
- reduce sidetracks and pilot holes.
Interval velocities give you the necessary input data to constrain the pore pressure models while drilling and thus optimize mud-weight selection, helping to save unnecessary casings and produce a larger section.
The seismicVISION service uses the latest technology developments in our Q-Borehole integrated borehole seismic system, including
The seismicVISION service has been awarded by several E&P-recognized communities as "The Best Exploration Technology" being used from zero offset to vertical incidence VSP surveys.
