However, many non-reservoir anomalies exist, too. Borehole seismic measurements can be used for a number of purposes including the estimation of rock property values, seismic propagation understanding, interpretive assistance, and standalone imaging. Earthquake hypocentral location techniques are used to plot the fractures as they occur in time. This absorption or Q factor can be used as a rock property or in a Q-compensation technique with surface seismic data Figure 6. Sun, Z.
drillnoise vertical seismic profile Schlumberger Oilfield Glossary
A class of borehole seismic measurements used for correlation with surface seismic data, for obtaining images of higher resolution than surface seismic images. Our new distributed acoustic sensing (DAS) system reduces VSP acquisition time from the hours required by conventional seismic operations to just minutes. Our VSP processing is conducted using Q-BorSeis borehole seismic processing, a fully integrated suite of applications in the Omega geophysical data.
A crane is used to deploy the wireline and tool in the well. Moving to farther offsets the shallow first arrivals are actually upcoming refractions.

A previous broad-band and a recent high-resolution 3-C line are also shown in the figure modified from Margrave et al.
walkaway VSP Schlumberger Oilfield Glossary
Walkaway VSPs in which the receivers are placed just above the reservoir are gaining acceptance as a tool to quantify seismic attributes and calibrate surface. In geophysics, vertical seismic profile (VSP) is a technique of seismic measurements used for Schlumberger Oilfield Glossary: vertical seismic profile .
We note that hydrophone receiver strings can also be effectively used in VSP surveys.
Robert R. Detailed interpretation, phase-matching work, AVO efforts, and elastic-wave analysis can all benefit from VSP information.

|We interpret the red and orange colours amplitude values as sand indicators and blues as indicative of shales.
This book provides a review of the latest tools, technologies, and applications of borehole seismic technology.

Crabtree and Jan Dewar. We need a little more information from you before we can grant you access. A3C- 3D seismic survey was conducted in to attempt to differentiate reservoir from non-reservoir rock using converted waves.
