5 gravity data corrections

 

•Tidal correction •Latitude correction •Height correction => free air anomaly •Rock (height) correction => Bouguer anomaly •Isostatic correction => isostatic anomaly

height correction

free air anomaly

rock (height) correction

bouguer anomaly

direct wave reflected wave and air wave arrival on a CMP or shot gather

.

difference between static corrections: marine and land

marine: referenced to seabed/MSL/other

land: some depth usually below weathered level

k

in magnetics

magnetic susceptability

 difference between amplitude recovery and AGC

amplitude recovery is gain through logic means, AGC is cosmetic only

which V is the true medium velocity
