About this document
Passive Measurements in Formation Evaluation by AndriArdianPutra is a document available to read on EtoBox.
This document discusses passive well logging measurements including calipers, which measure borehole size, gamma ray logs, which provide information on lithology, and spontaneous potential (SP) logs, which measure electrical potentials in the borehole to identify permeable zones and estimate formation water resistivity through relationships between mud and formation fluid resistivities. Common terminology is defined and the principles of SP measurements are explained including how membrane potentials and li
