Intro To Logging
Introduction The logging of a well bore is the process of measuring the electrical resistivity of the surrounding formation and the fluids within. It is known that the electrical resistivity of rock is high however the resistivity of minerals and fluids that occupy the pore spaces of said rock have proven to be low in … Continue reading Intro To Logging
