发明名称 METHODS FOR DETERMINING MECHANICAL SPECIFIC ENERGY FOR WELLBORE OPERATIONS
摘要 An embodiment of method for determining mechanical specific energy for a wellbore operation (e.g., drilling) includes measuring power input to machines used in a wellbore and producing a value for input power. In addition, the method includes calculating mechanical specific power for the operation based on the value for the input power; a computer-readable media for performing a step or steps of the method.
