ABSTRACT:
A method associated with the production of hydrocarbons. In one embodiment, a method for drilling a well is described. The method includes identifying a field having hydrocarbons. Then, one or more wells are drilled to a subsurface location in the field to provide fluid flow paths for hydrocarbons to a production facility. The drilling is performed by (i) estimating a drill rate for one of the wells; (ii) determining a difference between the estimated drill rate and an actual drill rate; (iii) obtaining mechanical specific energy (MSE) data and other measured data during the drilling of the one of the wells; (iv) using the obtained MSE data and other measured data to determine one of a plurality of limiters that limit the drill rate; (v) adjusting drilling operations to mitigate one of the plurality of limiters; (vi) and iteratively repeating steps (i)-(v) until the subsurface formation has been reached by the drilling operations.
