''Crossplots'' (''XPLTs'') relate two or more different trace values to each other at the same depth, such as core [[porosity]] and bulk density. Each type of wireline tool measures a different rock property. By studying the same XPLT in many wells, distinctive data plot patterns related to these rock properties allow users to identify lithologies, porosities, parameters, and other geological and/or engineering relationships. | ''Crossplots'' (''XPLTs'') relate two or more different trace values to each other at the same depth, such as core [[porosity]] and bulk density.
