## What is Dix formula?

Dix formula The equation by which the interval velocity (v int) can be calculated for a zone between two depths on a seismic section. For two reflectors with reflected-ray travel times t 1 and t 2, and root-mean-square velocities v rms1 and v rms2 respectively, then: v int = [(t 2v rms2 2 – t 1v rms1 2)/(t 2 – t 1)] ½.

**What is RMS velocity seismic?**

The RMS velocity is that of a wave through sub-surface layers of different interval velocities along a specific ray path. From: Seismic Data Analysis Techniques in Hydrocarbon Exploration, 2014.

### What is RMS velocity in geophysics?

1. n. [Geophysics] The root-mean-square velocity is that of a wave through subsurface layers of different interval velocity along a specific raypath, and is typically several percent higher than the average velocity.

**How do you convert seismic time to depth?**

To convert time reflections to a depth surface we need to know the velocity. The depth is then estimated from the simple geophysical relationship that depth = velocity x time.

## What is the difference between interval velocity and average velocity?

We relate the average velocity to the rms velocity through a “heterogeneity factor” which is a quantity that gives a measure of the degree of velocity heterogeneity in the ground. The interval velocity is a quantity which varies according to the method of its derivation.

**What is RMS velocity formula?**

Root mean square velocity (RMS value)is the square root of the mean of squares of the velocity of individual gas molecules. v r m s = 3 R T M. Where. vrms= Root-mean-square velocity. M = Molar mass of the gas (Kg/mole)

### How do you calculate seismic velocity?

The rate at which a seismic wave travels through a medium, that is, distance divided by traveltime. Seismic velocity can be determined from vertical seismic profiles or from velocity analysis of seismic data.

**What is root mean square velocity formula?**

## How do you calculate velocity depth?

To convert time reflections to a depth surface we need to know the velocity. The depth is then estimated from the simple geophysical relationship that depth = velocity x time. The velocity of a rock is a fundamental physical property related to its hardness.
