The Rebco CD Sampler/Drive-Down Bailer is a dual-purpose tool engineered to take a physical debris sample from the obstruction site, or, in its longer drive-down configuration, to physically penetrate and capture a column of compacted debris for removal from the wellbore. The tool body consists of a top sub with a fishing neck, a primary collection tube, and an interchangeable bottom shoe valve. The angled mule shoe at the lower end helps guide the tool into debris and cuts a path of entry on the downstroke, while the ball or flapper valve at the base captures and retains the material on recovery.

In the sampler configuration (2 ft tube length), the tool takes a representative grab sample of debris at the work site, allowing the operator to assess debris type, particle size, and composition at the surface before selecting the most appropriate full-scale bailing or remediation method. In the drive-down configuration (5 ft tube length), the tool is used to physically penetrate and extract a full column of compacted sand, scale, or granular debris that cannot be lifted by pump action alone. The angled mule shoe helps force entry into hard-packed material on the downstroke.

Available with ball-type, flapper-type, or junk-catcher-type bottom shoe configurations, all of which are also available with optional mule shoe bottoms. Both 2 ft sample tube and 5 ft drive-down tube lengths are available as standard. Alternative tube lengths available on request. Available in 1½"–4" OD.
