Abstract: A spoolable array of sensors may be deployed within a wellbore and external a tubular string for measuring properties of a fluid in the central flow passage of the tubular string. A flow port may be made in the tubular string passing from the central flow passage to the external surface. Sensors of the spoolable array of sensors may be covered with a shroud and placed proximate the flow port, or such sensors may be isolated in a zone with packers along with the flow port. The spoolable array of sensors may additionally obtain pressure data to calculate a flow rate from a production zone. The spoolable array of sensors may also be employed in a non-flowing wellbore for monitoring nearby wellbores.

Abstract: A well system with an electrical control and sensing system includes a first conductor and a second conductor. A first switching circuit is coupled between the first conductor and the second conductor. The first switching circuit includes a first electrically powered device and a first diode coupled to the first electrically powered device. A sensor circuit is coupled between the first conductor and the second conductor. The sensor circuit includes a sensor and a sensor diode coupled to the sensor and configured to permit current flow through the sensor circuit from the second conductor to the first conductor.
