US 9,976,414 B2 · Downhole probe assembly with bluetooth device

Abstract

The embodiments described herein generally relate a downhole probe assembly incorporating a Bluetooth device for wirelessly transmitting electrical information between the downhole probe assembly and a surface electronic interface such as a computer when the probe assembly is above ground. The downhole probe assembly includes sensors for sensing downhole conditions; a controller in electrical communication with the sensors and configured to receive and process information from the sensors; a housing enclosing the one or more than one sensor and the controller; the Bluetooth device in electrical communication with the controller; and an end cap assembly fitted at one end of the housing. The end cap assembly partially surrounds the Bluetooth device and is configured for transmission of the electrical information therethrough. Also described is an end cap assembly for fitting to one end of a downhole probe assembly including a transmission module mated with and electrically connected to the Bluetooth device. The end cap assembly includes an end cap having an end cap mating section configured to mate with a mating section of the transmission module to form a chamber enclosing the Bluetooth device between the transmission module and the end cap. A known downhole probe assembly can be retrofitted with the Bluetooth device and end cap subassembly. The end cap subassembly is configured and adapted to promote signal transmission between the Bluetooth device and a surface computer or other electronic interface.
