Abstract
Apparatus including a side pocket mandrel for inclusion in a well tubing string for removably receiving an instrument in its offset receptacle bore for monitoring at least one parameter such as pressure, temperature or the like, at a downhole location, there being an electrical conductor (wire) extending from equipment at the surface downward to the side pocket mandrel and a plug in the lower end of the receptacle for electrically connecting the instrument in the receptacle with the conductor (wire) extending from the surface so that electrical energy may be transmitted downhole to power the instrument, that the instrument may generate electrical signals representing data sensed in the well and transmit them to the surface for processing and immediate display, printout, or storage.
