Overview
This patent protects a robust containment head designed to integrate with a tubing cleaning assembly to capture and manage residue and sprayed fluids as tubing is pulled from a well. Filed January 12, 2016 and granted October 22, 2019, the disclosure—by inventors based in Borger, TX—describes a cylindrical outer body surrounding a center aperture through which tubing passes, a wiping rubber sized to the tubing diameter, a support cylinder and bottom plate that together create a watertight reservoir, and a waste aperture for controlled drainage. The assembly is engineered to work with a spraying system that loosens residue while the wiping rubber removes solids, diverting the resulting debris and fluid into an enclosed reservoir that can be evacuated through a threaded waste collar or hose.
The prosecution secured detailed structural and functional claims covering alignment of apertures, welded reservoir construction, optional top plate retention, and load-bearing support to withstand upward and downward forces during tubing removal. The resulting patent portfolio reflects precise claim drafting that protects both the component-level innovations and the practical method of cleaning and containment in field operations.
Key Features
- Sealed reservoir formed by outer body, bottom plate and support cylinder
- Wiping rubber matched to tubing for effective debris removal
- Threaded waste aperture for hose attachment and drainage
- Optional top plate and mechanical fasteners for modular use
This containment approach improves operational cleanliness and safety on well sites and offers a durable, field-ready solution for tubing handling and maintenance in the oil and gas sector.
