Abstract
A method associated with the production of hydrocarbons. In one embodiment, method for drilling a well is described. The method includes performing drilling operations at one or more wells to a subsurface location in a field to provide fluid flow paths for hydrocarbons to a production facility. The drilling is performed by (i) obtaining mechanical specific energy (MSE) data and other measured data during the drilling operations; (ii) using the obtained MSE data and other measured data to determine the existence of at least one limiter; (iii) obtaining and examining lithology data for the well; (iv) identifying a primary limiter of the at least one limiter based on the lithology data; and (v) adjusting drilling operations to mitigate at least one of the at least limiter.
