CA 2671822

Methods and apparatus for mechanical specific energy-based drilling operation and/or optimization, compnsing detecting mechanical specific energy parameters, utilizing the mechanical specific energy parameters to determine mechanical specific energy, and automatically adjusting drilling operational parameters as a function of the determined mechanical specific energy. A drill string includes interconnected sections of drill pipe, a bottom hole assembly, and a drill bit. The bottom hole assembly may include measurement-while-drilling or wireline conveyed instruments. Downhole measurement-while-drilling or wireline conveyed instruments may be configured for the evaluation of physical properties such as weight-on-bit. While drilling, weight-on-bit and calculate mechanical specific energy data are used to determine subsequent mechanical specific energy

Procédés et appareil pour l'optimisation et/ou une opération de forage basé sur la MSE, comprenant la détection des paramètres MSE, l'utilisation des paramètres MSE pour déterminer la MSE, et l'ajustement automatique des paramètres de fonctionnement du forage comme fonction de la MSE déterminée.
