In 2012 Spectrographics identified a market for a Multi-Species Gas Logger. Currently drilling rigs measure the amount of gasses dissolved in the drilling fluid (mud) with instruments that measure total combustible gas. The industry wants that measurement to be separated into its hydrocarbon components (C1-C5). Chromatographs are often used to provide this measurement. They have two major drawbacks. They require significant and continuous maintenance. They take minimum of 10 seconds per reading. With current drilling speeds, this can represent several meters of hole.Specrographics Instruments has spent the past two year developing the tools, the mathematical algorithms, gas chambers and finding a sensor that can provide the spectral measurements required. We have tested the use of 4 different sensor technologies two Fabry-Perot interferometer (FPI) technology; one Michelson interferometer technology developed in Egypt and one using a new Canadian technology that provides tune monchromatic light. We have determined that a Canadian sensor is the best but most expensive while an Egyptian one seems to be good enough, is a more mature product and is less expensive.We are currently designing a rugged unmanned mud logging instrument using the Egyptian technology. Using spectroscopy our product will be both fast (1 sec update) and unmanned, low maintenance and rugged. No other technology has been shown to accomplish these two key
