DOWNHOLE TOOL WITH FUEL SYSTEM
A tool (1) for manipulating a material, includes a body (4) defining a chamber (6). At least one source (8) of a pressurised fuel and oxidant mixture (9) or of a monopropellant is in communication with a chamber via an injector device. At least one mechanism (18) for igniting the fuel and oxidant mixture or for initiating decomposition of the monopropellant is provided. Upon ignition of the fuel and oxidant mixture or initiation of the decomposition of the monopropellant, a combustion jet (20) or a decomposition product jet is formed in the chamber which, in use, flows out through a nozzle outlet (28) towards, and into engagement with, a material to be manipulated. Methods of using the tool (1) and fuel and oxidant compositions suitable for use in the tool are also described.

Green oxidizer compositions and methods
The present disclosure generally pertains to green oxidizer compositions and method of synthesizing and using the same. Such green oxidizers are stable, may be used in conventional bipropellant thrusters, including, but not limited to LDACS applications, and offer several benefits over conventional oxidizers with respect to toxicity and/or corrosion. The present disclosure also relates to methods of synthesizing poly-nitrated oxetane, a green oxidizer, in an Argon-rich environment.
