Abstract: A method and system for engineering a drilling bit program linked to rock removal at a cutting element/formation interface and specific to drilling of one or more wells in a given geographic area is disclosed. The system includes a first arrangement for planning the drilling of a particular well based upon a cascaded planning input and providing an engineered output which is a function of the cascaded planning input, wherein a level of the engineered output being dependent upon a level of the cascaded planning input. A second arrangement is provided for implementing the engineered output in the drilling of the particular well is also provided. Lastly, a third arrangement is provided for evaluating the implementation of the engineered output for the drilling of the particular well and providing an evaluation output. The evaluation output can be used by the planning arrangement as additional planning input for planning the drilling of a subsequent well in the geographic area.
