US 12,378,849 B2 · Tool for manipulating material using a pressurized fuel and oxidant mixture

Abstract

A tool (1), for example, a tool for use downhole in a tubular oil or gas well, and a method of deploying and operating the tool (1), are disclosed herein. The tool (1) includes a generally cylindrical body (4), which includes a chamber (6). A fuel source (8) is also included. The fuel source (8) is a pressurised fuel and oxidant mixture (9) which is released into the chamber by an injector device through injector nozzles (16). The fuel and oxidant mixture (9) is ignited to form a combustion jet (20). The combustion jet (20) exits the nozzle outlet (28) as directed combustion jets, which perforate the walls of the tubular oil or gas well 30, wherein the walls of the tubular oil or gas well represent a material to be manipulated.

Dependent claims

A tool for manipulating a material, the tool comprising:

a body defining a chamber;
at least one source of a pressurised combustible, not classified as explosive, fuel and oxidant mixture, in fluid communication with the chamber via an injector device;
at least one nozzle, each nozzle having an inlet and an outlet, the inlet being in fluid communication with the chamber;
and
at least one mechanism for igniting the pressurized combustible, not classified as explosive, fuel and oxidant mixture;
wherein, upon ignition of the pressurized combustible, not classified as explosive, fuel and oxidant mixture, a combustion jet is formed in the chamber which, in use, flows out of the tool through each nozzle outlet as a plurality of directed combustion jets directed towards, and into engagement with, a material to be manipulated.
