How to calculate two way time?

So, two-way traveltime is that of a normal-incidence wave with zero offset. So, in the Saleh’s answer you need to divided the TWT by 2. So, TWT/2 (s) * Velocity (m/s) = Depth (m). But, another aspect that you need to check, is that in seismic sections usually we work with milliseconds (ms) instead seconds (s).

How to 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.

How do you calculate seismic velocity?

The velocity of the wave is determined by the physical properties of the material through which it propagates. In the case of a vibrating string, c2 = F/ρ where F is the string tension force and ρ is the density.

What is a velocity model?

A velocity model maps out the layers of rock in a monitoring region and the expected speed that seismic waves (P-waves, S-waves, including anisotropic effects) will travel in each layer. …

How to calculate travel time and distance in Excel?

Again, we can use FILTERXML () to extract the relevant bits (=FILTERXML (C32,”//TravelDistance [1]”) and =FILTERXML (C32,”//TravelDuration [1]”)) The default output values are in KM for distance and minutes for duration. You can change this to miles, hours etc. too by using extra parameters in the lookup URL.

How to calculate travel time between two points?

Excel Calculate Distance between Two Points Using Excel to calculate distance & travel time between two points – Bing Maps API 1 Step 1: Fetch Latitude and Longitude for the addresses. 2 Step 2: Calculate distance between two geolocations. See More….

How to calculate the time between two times in Excel?

Another simple technique to calculate the duration between two times in Excel is using the TEXT function: Return hours and minutes between 2 times: =TEXT (B2-A2, “h:mm”) Return hours, minutes and seconds between 2 times: =TEXT (B2-A2, “h:mm:ss”) The value returned by the TEXT function is always text.

How to calculate the difference in days in Excel?

Display time difference as “XX days, XX hours, XX minutes and XX seconds” This is probably the most user-friendly formula to calculate time difference in Excel. You use the HOUR, MINUTE and SECOND functions to return corresponding time units and the INT function to compute the difference in days.
