WebDescription. The WST was a Schlumberger single axis check shot tool used for zero offset vertical seismic profiles (VSP). The WST consisted of a single geophone, pressed against the borehole wall, that was used to record the acoustic waves generated by an air gun located near the sea surface. A 120 in ³ air gun was suspended by buoys at a depth of 3 … WebJun 7, 2013 · Many different seismic velocity models can match the observed seismic data equally well, within the tolerance of measurement error, and this ambiguity grows rapidly away from known control points such as well logs. This also results in uncertainty in the true positions of anomalous geopressure zones interpreted from seismic.

WebNov 1, 2004 · There are many different areas and opportunities for errors in checkshot data: design, acquisition, processing, and publishing. Checkshot surveys are usually taken after all other logs have been ... 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.
