Continuous High Resolution Velocity as a 4D Attribute

4D (also known as time-lapse or repeat) seismic has in the past few years emerged as a<br>significant technique for monitoring fluid movement within reservoirs.<br>Understanding the relationship between changes in petrophysical parameters and the<br>corresponding change in seismic response has enabled geoscientists to monitor various<br>changes in fluid content within the reservoir and surrounding rocks.
