Title: SYSTEM, METHOD, AND DEVICE FOR POWERING ELECTRONICS DURING COMPLETION AND PRODUCTION OF A WELL
Abstract:
A system, method, and power control device for powering electronics located in a wellbore intersecting a subterranean earth formation. The system comprises a battery, a turbine generator, an electronic device, and a processor. The battery is locatable in the wellbore and the turbine generator is locatable in the wellbore so as to be in fluid communication with a flow path in the wellbore. The electronic device is locatable in the wellbore and electrically coupled to the battery and the turbine generator. The processor determines if a power condition is satisfied to allow the turbine generator to power the electronic device. The method comprises powering an electronic device located in the wellbore using a battery and opening a closed flow path in communication with a turbine generator. The method also comprises powering the electronic device using the turbine generator if a power condition is satisfied.
