Compensated Density Logging Tool 2009 All Rights Reserved-Century Wireline Services
The Series 9239, Compensated Density logging tool uses the two focused density detectors to compute borehole compensated density real time while logging. No post processing required to produce CDL bulk density. Additionally, the tool also records natural gamma, caliper , and focused guard resistivity
