Abstract
En anordning og fremgangsmåte for testing av formasjoner i et brønnhull ved å bruke et spektrometer, innbefatter en bærer som kan transporteres inn i et brønnhull som krysser en undergrunnsformasjon av interesse, et antall haovlederlyskilder anordnet på bæreren, en fluidprøvecelle som mottar lys utsendt fra antallet halvlederlyskilder og minst en fotodetektor som detekterer lys utsendt fra antallet halvlederlyskilder etter at lyset har vekselvirket med et fluid i fluid-prøvecellen.
