The trace data was originally processed using a SRD of 800m. The time traces have been shifted using replacement velocity of 2000 m/s from the original SRD of 800 m to a new 0 m MSL datum. In Configure project, set the SRD to 0m (MSL). In this example: 0 m = 0 ms.

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.
