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.
