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. Suitable kickover tools and running tools are also disclosed. In addition, method and means for running and installing a well device in a receptacle in a well are also disclosed wherein louvered friction members are utilized to releasably connect the well device to a running tool, by which it is lowered into the well, and also for retaining the well device in said receptacle.
