Hydrocarbon detection while drilling (HDWD) is important for obtain proper drilling performance. In this report, Raman spectra for hydrocarbon in returned water based drilling fluid have been acquired using He-Ne laser (633nm) excitation. The relative intensities of several Raman bands are found to depend on the concentration of hydrocarbon in returned drilling fluid. Spectra are interpreted as indicating that Raman spectra could be used as potential method for HDWD.

Raman microspectroscopy is now well established as one of the most powerful analytical techniques for a diverse range of applications in physical (material) and biological sciences. Consequently, the technique provides exceptional analytical opportunities to the science and technology of biosensing due to its capability to analyze both parts of a biosensor system—biologically sensitive components, and a variety of materials and systems used in physicochemical transducers. Recent technological developments in Raman spectral imaging have brought additional possibilities in two- and three-dimensional (2D and 3D) characterization of the biosensor’s constituents and their changes on a submicrometer scale in a label-free, real-time nondestructive method of detection. In this report, the essential components and features of a modern confocal Raman microscope are reviewed using the instance of Thermo Scientific DXRxi Raman imaging microscope, and examples of the potential applications of Raman microscopy and imaging for constituents of biosensors are presented.
