摘要： A sampling tool to sample core samples from a wellbore is disclosed. A core sampling storage module includes a pressure housing to store a plurality of core samples, a core tube within the pressure housing, the core tube to store a plurality of core samples drilled from a downhole formation, a pressure housing cover that is configured to be selectively rotated to an open position or a closed position, an activation mechanism to receive a command, and based on the command, open or close the pressure housing cover, a push rod to selectively install a plug to cover the core tube, wherein when the plug is installed the pressure housing maintains a pressure.

摘要： The presence of organosulfur compounds in a substance may make analyses of the substance difficult, particularly in the presence of interfering compounds. Methods for analyzing a substance may comprise: providing a substance comprising an organosulfur compound; optically interacting electromagnetic radiation with the substance and an integrated computational element; and analyzing for the organosulfur compound in the substance using the integrated computational element.

摘要： A light source and a method for its use in an optical sensor are provided, the light source including a resistively heated element. The light source includes a power circuit configured to provide a pulse width modulated voltage to the resistively heated element, the pulse width modulated voltage including: a duty cycle with a first voltage; and a pulse period including a period with a second voltage, wherein: the duty cycle, the first voltage, and the pulse period are selected so that the resistively heated element is heated to a first temperature; and the first temperature is selected to emit black body radiation in a continuum spectral range. Also provided is an optical sensor for determining a chemical composition including a light source as above.
