71.
The maximum foldage obtained from a 48-channel common depth point
(CDP) reflection survey with the geophone and shot point spacing of
50m and 100m respectively , is.....
Solution:
Foldage
= 1/2 ((number of channls or geophones *(Receiver spacing / shot
spacing) ) --------(1)
Given
values
Number
of channels = 48
Receiver
spacing = 50 m
Shot
spacing = 100m
Foldage
= 1/2 ( ( 48* (50/ 100) )
Therefore
Foldage = 12
THANK YOU SO MUCH BRO
