AI Technical Summary

Benefits of technology

The patent is about a molded slip assembly that has a shear ring and a plurality of slip segments that form a solid ring. Each slip segment also has a drillable base that can be drilled during use. The technical effect of this design is that it allows for easier and more efficient drilling of wells during oil field drilling operations.

Problems solved by technology

Thus, these types of downhole tools are often subject to high differential pressures.
Because slips must have sufficient strength to anchor the downhole tool in the wellbore, constructing slips from easily drillable materials can be challenging.

Abstract

A molded slip assembly comprises a shear ring coupled to a plurality of slip segments to form a unitary solid ring and a plurality of drillable bases. A drillable base is molded to an inner surface of each of the plurality of slip segments.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to U.S. Provisional Application Ser. No. 62 / 038,141 filed on Aug. 15, 2014, and entitled “Molded Shear Slip,” which is hereby incorporated herein by reference for all purposes.BACKGROUND[0002]This disclosure relates generally to methods and apparatus for anchoring downhole tools in a wellbore. More specifically, this disclosure relates to methods and apparatus for anchoring downhole tools in a wellbore using a slip assembly at least partially constructed from drillable materials.[0003]In drilling or maintain wellbores, it is often desirable to anchor a downhole tool within the wellbore. Downhole tools that are often anchored in wellbores include, but are not limited to, packers, bridge plugs and frac plugs, and are well known in the art of producing oil and gas. These types of downhole tools are generally used to isolate the portion of the wellbore below the downhole tool from the portion of the wellbore a...
