Magnetic Field Disruption For In-Well Power Conversion

Abstract

The system invention is based on the use of electromagnetics that convert flow and mechanical motion into electrical power. The system is housed in a side pocket mandrel. Flow is diverted from the main bore through the side pocket, which houses a pressure vessel. At least one magnet is housed in the pressure vessel, and at least one coil is wound around the pressure vessel. As the diverted flow from the well passes through the side pocket, the pressure vessel may rotate or vibrate, creating a disturbance to the magnetic field, thereby creating current. An electronics harvesting module is connected to the ends of the coil which can harvest, regulate, and store power.

1 . A system for generating in situ power inside as well comprising;
 a. a mandrel with a main bore and a side pocket wherein a portion of a well's fluid flows through the side pocket;   b. a pressure vessel disposed within the side pocket wherein a module within the pressure vessel rotates or vibrates from the flow diverted through the side pocket;   c. at least one magnet disposed within the pressure vessel;   d. at least one coil wound around the pressure vessel; and   e. an electronics harvesting module connected to the ends of the coil that harvests, regulates, and stores power from the coil.   
     
     
         2 . The system of  claim 1  wherein the electronics harvesting module stores power with rechargeable batteries. 
     
     
         3 . The system of  claim 1  wherein the electronics harvesting module stores power with capacitors. 
     
     
         4 . The system of  claim 1  wherein the electronics harvesting module stores power with a retainer of electricity.
