AI Technical Summary

Benefits of technology

This patent describes a frac-ball that can be used in a well casing to initiate an exothermic reaction to seal the environment and prevent fluid flow. The frac-ball is made up of a material with two different metallic components that can react with each other. The patent also includes a system for segmenting the well casing and a method for using the frac-ball to seal the environment. The technical effects include improved well casing engineering and more efficient oil drilling.

Problems solved by technology

The frac-ball is configured to function as a seal within the segmentation device disposed in a well casing environment prior to an exothermic reaction, and subsequent to an exothermic reaction is incapable of functioning as a seal within the segmentation device disposed in the well casing environment.

Embodiment Construction

[0030]Now referring to FIG. 1, an exemplary embodiment of a wellbore 20 disposed in a subterranean formation is shown. The wellbore 20 includes a fluid conduit (typically referred to as a “casing”; e.g., casing 22) disposed within a drilled bore extending below surface level 24. The wellbore 20 is diagrammatically shown as having a substantially vertical oriented section 26, a substantially horizontal oriented section 28, and an arcuate section 30 connecting the vertical and horizontal sections 26, 28. The present disclosure is not limited to use with any well bore configuration relative to the surface. For purposes of describing aspects of the present disclosure, the casing 22 is described herein as including casing segmentation devices 32, packers 34, and pipe sections 36. The pipe sections 36 include a wall 38 that surrounds and defines an internal flow passage 40. The described well casing configuration reflects a typical configuration and the present disclosure is not limited t...

Abstract

A frac-ball, a system including the frac-ball, and a method using the frac-ball are provided. The frac-ball includes a body and an exothermic reaction initiator. The frac-ball body includes a material having at least two dissimilar metallic constituents, which dissimilar metallic constituents are configured to permit an exothermic reaction there between. The exothermic reaction initiator is in communication with the body, and is configured to selectively initiate an exothermic reaction between the two dissimilar metallic constituents.

Description

[0001]This application claims priority to U.S. Patent Appln. No. 62 / 609,694 filed Dec. 22, 2017, which is hereby incorporated by reference.BACKGROUND OF THE INVENTION1. Technical Field[0002]The present disclosure relates to subterranean well casing segmentation devices in general, and to frac-balls for use in well casing segmentation devices, well casing segmentation device systems using frac-balls, and methods related thereto in particular.2. Background Information[0003]Subterranean wells can be used to locate and extract subterranean disposed raw materials. For example, wells may be used to locate and extract hydrocarbon materials (e.g., hydrocarbon fluids such as oil, and gases such as natural gas) from subterranean deposits. A water well may be used for locating and extracting potable or non-potable water from an underground water table. A well configured and located to locate and extract hydrocarbon materials typically includes a tubular casing disposed subsurface within the we...
