Abstract: Drill bit wear can be quantified through an analysis of chemical reactions that occur during drilling. A detector measures the molar composition of a dissolved gas sample. From the molar composition, the moles of hydrogen, ethylene, and propylene in the dissolved gas sample are determined. A thermal cracking reaction and a thermal decomposition reaction determine moles of hydrogen produced during drill bit wear based on the moles of ethylene and propylene. The moles of hydrogen produced is subtracted from the total moles of hydrogen to determine moles of hydrogen produced by metal oxidation. A metal-water reaction determines the moles of metal that have been oxidized. This can be converted into mass or volume of metal loss to quantify drill bit wear.

Abstract: A method of mud logging is disclosed which the chemical constituents and concentrations of formation fluid are calculated based on pulse power plasma parameters and the constituent species and concentrations of drilling mud, including reaction products, upon which the pulse power plasma has acted. Based on correlation between pulse power plasma parameters, including drilling parameters, drilling can be optimized for identified formation and formation fluid species. An offset between the chemical makeup of the drilling mud exposed to pules power plasma and the chemical makeup of formation fluid is calculated. Based on the calculated offset, pulse power plasma drilling can be controlled as a function of drilling mud concentration including in other wellbores in the formation or field.

Abstract: An imaging device (124), laser(s) (190, 192), lag calculation, and/or volume calculations are used to determine cuttings volume per unit depth. A projected or theoretical volume can be calculated based on parameters of the borehole being drilled. At the surface of the borehole, cuttings can be captured in a shaker screen (108). The volume of the cuttings can then be directly measured on the shaker screen. Deviations from a projected volume can be logged and notifications can be communicated on and/or offsite of the borehole. Additionally, size and shape of cuttings can be logged. Deviations from projected size and shape can also be logged. Various hydrocarbon recover}? operations can be altered based on results of the cuttings analysis and other indicators of improper hole cleaning. For instance, the drilling can be stopped, or a direction of the borehole can be altered.
