Abstract: Method and apparatus used to deploy and process eutectic metal alloy material into an oil, gas or water well for the purpose to plug and seal selected downhole casing leaks. The apparatus includes a power control unit located at surface and a downhole tool that is lowered into the well by standard wireline cable. The downhole tool delivers the necessary quantity of metal alloy, forms the required temporary bridge plug support for containing the molten alloy, melts the alloy by means of electric heating, heats the surrounding wellbore formation, squeezes the molten alloy through the perforations and recovers any excess alloy for subsequent recycling.

Abstract: A method and apparatus is disclosed to seal and prevent fluidic communication in the annulus between a cemented and drilled through casing float shoe and a well-bore formation. The present invention provides a component that installs as a coupling unit between a well casing shoe track and a float shoe which integrates a fusible metal alloy. After the well casing is cemented into the well-bore according to conventional procedures, the metal alloy may be melted using a downhole heating device deployed within the casing to a location adjacent to the alloy, thereby causing the alloy to flow, infill, plug and seal any incompetent cracks or micro-annulus conditions within and about the cured cement and well-bore formation.

Abstract: A method and system for determining the location of objects within a geographic area is disclosed. In one embodiment, the system includes a plurality of portable transceiver devices each coupled to a respective object located within the geographic area; a plurality of stationary transceiver devices fixed at predetermined locations within the geographic area, wherein the plurality of stationary transceiver devices are each configured to determine received signal strength (RSSI) values of signals transmitted by the plurality of portable transceiver devices; and a base station, comprising a base station transceiver device and a computer coupled to the base station transceiver device, wherein the base station is configured to receive RSSI values from at least one of the plurality of stationary transceiver devices and calculate a location of at least one portable transceiver device based on the received RSSI values.

Abstract: An apparatus and method for disassociating natural gas from a deposit of natural gas hydrates and producing natural gas. A reactor module is located downhole in a heating and injection well. Water is provided to the reactor module where it is heated and a solvent is injected into the water prior to heating. The heated water and solvent passes to the deposit of natural gas hydrates where the natural gas is disassociated under the influence of the heat from the reactor module.

Abstract: Method and apparatus used to deploy and process eutectic metal alloy material into an oil, gas or water well for the purpose to plug and seal selected downhole casing leaks. The present invention provides an integrated solution for plugging and sealing of selected casing perforations while leaving the casing bore open to the net inside surface thereby eliminating the need for secondary milling or drill out operations. The apparatus consists of a power control unit located at surface and a downhole tool that is lowered into the well by standard wireline cable. The downhole tool delivers the necessary quantity of metal alloy, forms the required temporary bridge plug support for containing the molten alloy, melts the alloy by means of electric heating, heats the surrounding wellbore formation, squeezes the molten alloy through the perforations and recovers any excess alloy for subsequent recycling.

Abstract: A heating tool used for heating cement and/or a ground formation zone and melting billets in a down hole application for sealing oil and gas wells from gas migration. The heating tool has a billet loader which allows a plurality of billets to be loaded into the top of the tool and which billets then pass downward into a magazine and the lowermost heating area of the tool to rest on a billet retainer.

Abstract: An induction tool for heating well casing and a method for using and manufacturing the tool. The tool comprises a magnetically permeability core and an electrically conductive coil surrounding the entire circumference of the core. The tool generates magnetic flux which flux is used to heat well casing adjacent to or acted upon by the tool. The heated well casing may be used to melt material used for well sealing.
