Abstract
A borehole logging system for the measure and the telemetry of properties and conditions of a well borehole environs. The system is embodied to measure fluids within the borehole, to measure high resolution images of the wall of the borehole, to transfer of data to and from equipment operating within the borehole environment, and to determine the status of equipment operating within the borehole. The embodiments are based upon emission, measurement and processing of electromagnetic radiation in the near infrared (NIR) region of the radiation spectrum.
