Flushed oil effect induction log
WebEffect of Invasion of Drilling Fluid on Log Response During drilling, the pressure of the drilling fluid column is generally higher or slightly higher than reservoir pressure. Therefore, for a permeable reservoir, the invasion of drilling fluid filtrate into the reservoir is an accustomed situation. WebInduction logs are designed to measure the conductivity of rock formations by using the electromagnetic principles outlined by Faraday, Ampere, Gauss, Coulomb and unified in a single theory by James Maxwell in 1864. The process involves the interaction of magnetic and electric fields:
