Quick Reference

The velocity of waves through subsurface media down to the nth interface, such that Vrms = (ΣVint2titi)Z\x, where Vint and ti are the interval velocity and single-travel time through the ith interval. Vrms is usually derived from normal moveout measurements from a T2X2 graph, and is commonly several per cent larger than the corresponding average velocity.
