Is this an oil reserve as the Z values are all very negative??

You will need to spilt out the XYZ in Excel to create a points file I assume you will need the first 3 colums of data. When you have done this follow the tutorial examples for using point files to create surfaces.

Hi arturopolanco

The attachment was fine when I downloaded and I loaded it into my program. It but I did not have the value for the total volume of the reservoir when I checked the surface analysis.

If you have created a surface for your resevoir, you also need to create a surface to compare to.  C3D can then calculate the volume between the two surfaces.

Extract the highest contour from your surface, and use it to create a flat surface across  the top of the resevoir.  Then create a Volume surface, using these two surfaces as 'Base' and 'Comparison'.  The volume between the two will be in the properties of the Volume surface.

Thanks for your respond. I got the volume now, Please can you give or direct me to any materials or web site, paper that can show the the mathematical behind the method used by program in civil3D to generate the volume.
