Multi-phasic explosive fracturing system

A down hole modular rock fracturing system comprising:

• one or more multiphase explosive containers comprising a precursor composition located down hole;
• one or more liquid supply containers comprising liquid fuel;
• one or more venting containers;
• liquid supply pipes connecting the liquid supply containers to the multiphase explosive containers;
• a remote valve or pump located in the liquid supply pipes between the liquid supply containers and the explosive containers thereby separating the liquid fuel from the precursor composition;
• a vent pipe connecting the multiphase explosive containers to the venting containers;
• and
• a control cable connected to the remote valve or pump, wherein the remote valve is configured to be opened or the pump activated at a signal from the control cable and wherein when the valve is opened or the pump is activated, the liquid fuel moves through the liquid supply pipes into the multiphase explosive containers thereby creating an explosive composition;
• wherein one or more of the multiphase explosive containers is cylindrical and comprises:
• a cylindrical outer casing;
• a cylindrical intermediate shell;
• and
• a cylindrical central shell;
• wherein precursor composition is located in the annular space between the outer casing and the intermediate shell and wherein the intermediate shell and central shell comprise fill holes;
• and
• wherein the central shell is connected to the liquid supply pipes.

• wherein one or more of the multiphase explosive containers is cylindrical and comprises:
• an outer casing;
• an internal perforated vent pipe connected to the vent pipe;
• a perforated liquid supply pipe connected to the supply pipe;
• and
• a precursor composition;
• wherein when the multiphase explosive container is angled horizontally, the internal liquid supply pipe is located at the bottom of the container and the internal vent pipe is located at the top of the container such that liquid running through the internal liquid supply pipe exits through the perforations in the internal perforated liquid supply pipe, fills the container, and exits through the internal vent pipe.
