Downhole® Deployment Valve (DDV)

"Weatherford's DDV tool allows safe installation of drillstrings and completion assemblies during underbalanced operations and increases well productivity by avoiding formation damage.

The DDV tool reduces well costs and risk exposure with faster tripping and elimination of the need for snubbing units.
