What is videographing used for?

Video graph or camera test is useful only to ascertain the type of formation and sequences of the strata encountered. Video testing can be done in the water column to analyse and reassess the formation details. It is used in problematic wells to find out the cracks and fractures and its depth, so as to ascertain the packer installation depths for hydro fracturing or blasting. It is useful in solving some well construction problems where it will be difficult without the data of the strata structures.
