A production logging device, insertable into a cased or uncased wellbore for determining concentration of specified components in flowing production fluid, is provided having a tool body sized smaller in diameter than the wellbore so that flowing fluid production is not blocked. A line is connected to the tool body by which movement of the tool body within the wellbore casing can be selectably controlled from a remote location, and by which information signals can be communication from the tool body to the remote location. An infrared radiation source operatively connected to the tool body. A plurality of infrared transmission sites are circumferentially spaced around the tool body directed so that infrared radiation from the infrared radiation source is transmitted through flowing production fluid in the wellbore. A plurality of infrared receptors are circumferentially spaced around the tool body and are positioned so that infrared radiation transmitted through flowing production fluid is received at the plurality of receptors. An infrared analyzer is carried by the tool body, operatively connected to infrared receptors, so that the spectrum of infrared radiation transmitted through production fluid can be determined.
