if the value of said rate of penetration, at a time sample, is below said first threshold value, performing of the following operations:
calculation of a mean value of said rate of penetration, over a time interval, said interval beginning at said time sample and said interval and comprising a sufficient number of time samples for covering an interval of drilling length greater than or equal to a second threshold value, said operation of calculating the mean value being performed by a processor of a computer;
comparison of said mean value with said first threshold value, said operation of comparison being performed by a processor of a computer;
for each sample of said third time series comprised in said time interval, comparison of the value of concentration of said at least one gas species with a third threshold value, said operation of comparison being performed by a processor of a computer.

METHODS OF FABRICATING POLYCRYSTALLINE DIAMOND BY FUNCTIONALIZING DIAMOND NANOPARTICLES, GREEN BODIES INCLUDING FUNCTIONALIZED DIAMOND NANOPARTICLES, AND METHODS OF FORMING POLYCRYSTALLINE DIAMOND CUTTING ELEMENTS

BAKER HUGHES INCORPORATED...

1. A method of fabricating polycrystalline diamond, comprising:functionalizing surfaces of diamond nanoparticles with fluorine;
combining the functionalized diamond nanoparticles with a polymer to form a mixture;
forming the mixture comprising the functionalized diamond nanoparticles and the polymer into a sheet, the sheet comprising the functionalized diamond nanoparticles dispersed within the polymer; and
subjecting the sheet comprising the functionalized diamond nanoparticles dispersed within the polymer to high pressure and high temperature (HPHT) conditions to form inter-granular bonds between the diamond nanoparticles, wherein carbon atoms of the polymer bond with one or more of the diamond nanoparticles to promote formation of the inter-granular bonds between the diamond nanoparticles.
