DOWNHOLE MICROWAVE HEATING
A practical downhole microwave tool and method of radiating the microwaves into
a formation has been developed and initial experiments carried out. (Patent
Pending). This tool is illustrated above. Unlike previous microwave concepts, small
magnetrons are located in the tool. Proprietary techniques are used to make the
tool small, just 2 and 7/8" in diameter, consistent with production tubing
dimensions. The tool is built into an upset of production tubing in order to make up
into the tubing string with normal production techniques.
By radiation, the energy can be deposited in the formation much farther away from
the well than techniques such as resistance heating that depend on thermal
conduction.
