need help. how to do regional velocity analysis?

Mr GEO2000
thank you for answer , ofcourse i respect that you have Master of Science in Petroleum Geology and Geophysic
but i didn't ask you about your degrees
i asked you about this method to convert gravity into regional velocity ... which is absolutely unknown in Petroleum Geology and Geophysics , i wanted to know more information about it.
i would like to ask in which country you are working ? because in my country we don't know any thing about gravity into regional velocity ... because gravity methods has very low resolution and too low accuracy , what i know (honestly i know very few about gravity) is that we use gravity only qualitatively , while the density values from gravity are inacurate and represent very thick section of the subsurface , so ..... it's (as i understand) useless in the oil exploration....
i would like to know more about this subject , and it is good chance to know directly from some one how applied this technique practically , if you can give us a presentation or paper about your work or any other project to understand the technique , it will be very kind of you.
thanks

Hi Ahmedsisy
So sorry to understand your question, any way to converation of gravity to velocity is based on Naf& Drake methods, as we know that gravity is function of density. By using Naf&Drake methods you can convert density to velocity or vice versa.
I did used gravity and magnetic in South Atlantic marin for re-construct and light shadow of that margin (West Africa-Brazil).
What you need to do is use one of the software programs like (GMT if you have the data for area of interest or use GeoSoft), point out your coordinate and start plotting. These programs will create for you plot and files.
Sorry again for misunderstanding your question dear.
