WebThe service 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 high-speed MWD telemetry for quality control of downhole data. WebThe check-shot survey uses only the direct path traveltime. In addition to tying well data to seismic data, the vertical seismic profile also enables converting seismic data to zero-phase data and distinguishing primary reflections from …

WebInline Checkshot Tool (QSST*) Description The Schlumberger QSST was a single-axis seismic checkshot tool that ran in-line with the triple combo tool string. The QSST consisted of a single hydrophone and did not utilize a clamping arm like the WST to force it into contact with the borehole wall. WebSeismic checkshot times are used as a reference to calibrate the sonic log through a process called drift curve correction. The drift curve is a log of the difference between integrated sonic log time and check shot seismic time. When integrated sonic log times are higher than seismic times (the usual case), drift is negative.
