Velocity is the Key Element for 3-D Earth Models

Velocity is the Key Element for 3-D Earth Models


Until recently, velocity was perhaps the most misunderstood and maligned geophysical parameter in interpretation.  However, the advent of abundant 3-D seismic data, fueled by a decrease in risk tolerance and increase in cost containment, has resulted in velocities being appropriately scrutinized and appreciated.  Today, velocity is recognized for what it is; a key parameter that is capable of significant impact, yet complex and difficult. Presented is a discussion on the characteristics of a viable velocity database. An example demonstrates a common exploration problem, and the need for rigorous treatment of valid velocity data and for the interpreters to remain vigilant to a few simple truths.
