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

Tool for manipulating material using a pressurized fuel and oxidant mixture

A downhole tool () for manipulating a target, includes a housing (). The housing includes an inner surface () configured for mounting to a tubular carrier; and an outer surface (). At least one chamber () is provided between the inner surface () and the outer surface () and contains at least one propellant source () and an ignition system. One or more outlets () lead from the chamber () to the outer surface (), for combustion products from the at least one propellant source. The downhole tool may be employed for perforating and may be included in a hydraulic fracturing assembly. A method of hydraulic fracturing in a wellbore using the tool is provided.
