MILLING AND WELLBORE METAL DEBRIS RECOVERY ASSEMBLY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18092719 titled 'MILLING AND WELLBORE METAL DEBRIS RECOVERY ASSEMBLY

The milling and wellbore metal recovery assembly described in the patent application is designed to efficiently remove debris resulting from milling a casing in a wellbore.

The assembly includes a milling assembly capable of milling a casing in a wellbore.
A primary debris removal assembly is connected to the milling assembly and can clear debris by reverse circulating wellbore fluid in an uphole direction.
A secondary debris removal assembly is connected to the primary debris removal assembly and can clear debris by circulating wellbore fluid in a downhole direction through the secondary debris removal assembly.

Potential Applications: - Oil and gas industry for wellbore operations - Mining industry for drilling and extraction processes

Problems Solved: - Efficient removal of debris during casing milling operations - Improved wellbore maintenance and cleanup procedures

Benefits: - Enhanced wellbore productivity - Reduced downtime for cleaning and maintenance

Commercial Applications: Title: "Efficient Debris Removal Assembly for Wellbore Operations" This technology can be used in oil and gas drilling operations, mining activities, and other industries that involve wellbore maintenance and cleanup.

Questions about the technology: 1. How does the milling assembly in this technology differ from traditional milling tools used in wellbore operations? - The milling assembly in this technology is specifically designed to efficiently remove debris while milling a casing in a wellbore, unlike traditional milling tools that may not have dedicated debris removal mechanisms.

2. What are the key advantages of using a primary and secondary debris removal assembly in this technology? - The primary and secondary debris removal assemblies ensure thorough debris removal during casing milling operations, leading to improved overall efficiency and reduced maintenance requirements.

Original Abstract Submitted

A milling and wellbore metal recovery assembly includes a milling assembly that can mill a casing disposed in a wellbore. A primary debris removal assembly is connected to the milling assembly and can reside uphole of the milling assembly. The primary debris removal assembly can clear debris resulting from the milling assembly milling the casing disposed in the wellbore by reverse circulating wellbore fluid in an uphole direction from an annulus formed by the wellbore and through the primary debris removal assembly. A second debris removal assembly is connected to the primary debris removal assembly, and can reside uphole of the primary debris removal assembly. The secondary debris removal assembly can clear debris resulting from the milling assembly milling the casing by circulating wellbore fluid in a downhole direction through the secondary debris removal assembly and then in the uphole direction through the annulus towards a surface of the wellbore.
