2D Seismic Refraction Tomography

This video provides an entire field demonstration of how to set up and do a 2D seismic refraction tomography. The method can image hundreds of feet. Seismic refraction tomography utilizes seismic (P and S) waves refracted on geological layers to image velocity contrasts of the subsurface. It works similar to the classical seismic refraction methods; however, data acquisition uses more seismic shots. Cordillera Geo-Services produces seismic survey services anywhere for multiple applications in environmental, engineering, mining, groundwater, and construction projects.

Do you provide a full training on the equipment and the technique with the data interpretation?

[@hectorhinojosa-cgs]

Yes I do! Please let me know if you need anything.

Hello Mr. Hinojosa, im geophysics student and i have great in seismic refraction. I do have some questions:
-how do choose the position of the source in relation to the the geophones (before the first geophone, in the middle!?)? do you have the same spacing for all these positions?
-in the case of the bedrock mapping, we know that the depth of interest should 3 to 5 times the geophones total length, do you control by varying the source, like the farther the source the deeper our geophysical investigation will be? thanks you for your infos!

[@hectorhinojosa-cgs]

Hi Kone,
I apologize for the super delayed response...Life got in the way...
Answer to Question 1: For seismic refraction tomography I like to do it before the first geophone, between each geophone, and after the last geophone. So the more sources/impacts, the better (higher resolution). You can space the source location any way you want. I prefer to use close spacing (1 or 2 m) and equidistant.
Answer to Question 2: Yes, the farther the source the deeper the imaging depth, but that also implies that the source is larger. Deeper imaging depths require larger sources.

Hello Sir, What is the maximum depth this technique can reach?

[@rajeshtelluri]

Are we using roll along method...?

[@hectorhinojosa-cgs]

Not in the example shown in the video.

[@alosh515]

Hello, can you tell me the name of the device and the country of manufacture?

[@hectorhinojosa-cgs]

I am happy to sell you a system.
