Description /Application

Bilco's Multi-Use Waste Retriever is designed to catch particulate matter that has been dislodged as a result of a successful jetting operation.  Run in conjunction with a variety of Jetting Tools and a Flow Check Sub this screen-filtering device will eliminate debris slipping into the well bore.  The Multi-Use Waste Retriever and Jetting Assembly should be incorporated in the Wear Bushing Retrieval run to save rig time.

Operation

Robust in design, the Multi-Use Waste Retriever should lead the assembly in the hole with a stand spaced between the Flow Check Sub and Well Head Jetting Tool assembly.  The Wear Bushing Retrieval Assembly should be spaced above with ease of handling in mind, then workstring to surface.  As the Wear Bushing is retrieved the exact distance is pulled to place the Jetting Tool across the wellhead profile.  The jetting operation will dislodge debris and clean the wellhead profile in preparation for the hanger assembly.  Heavy debris that is introduced in the fluid stream will be captured in the Multi-Use Waste Retriever and any debris that is suspended will be filtered through the screen mesh when pulling out of the hole.
