Example of a Composite Wireline Display for Environmental Projects  



A significant issue in environmental site characterization is identification and mapping of subsurface zones of high permeability, usually buried channel deposits at sediment covered sites.  The above composite wireline display was developed for a client who was routinely running E-Logs, Gamma Ray, Induction, Guard Logs and Caliper Logs in their characterization and remediation wells.  These composite displays allowed the project geologist and remediation engineer to quickly locate and map high permeability zones for input into the remediation design for the site.
