Lithology log response

WebLithologies affect the density, neutron and sonic logs. Invasion of mud filtrate into porous formations affects resis- tivity readings, and temperature affects the resistivity of both filtrate and saline formation water. Some resistivity tools work in nonconductive bore- hole fluids, others only work in salt saturated mud systems.
