==Effects of organic matter on well logs==
==Effects of organic matter on well logs==
The increasing concentration of organic matter in a rock directly affects its properties by lowering density slowing sonic velocity increasing radioactivity raising resistivity and raising hydrogen and carbon contents. All of these [[attributes]] can be measured using density sonic, neutron, [[Basic open hole tools#Gamma ray|gamma ray]], and resistivity logs. The table below (from <ref name=ch06r7 />) summarizes log responses to organic matter.
