Abstract: Methods, computing systems, and computer-readable media are provided. A carbon footprint baseline is established for a drilling unit. Power consumption is calculated for drilling unit components. The power consumption of components is converted to CO2 emissions according to a GHG standard. The power consumption is transformed into real-time power consumption during drilling operations using power ratings, diversity factors, fuel usage, and specific fuel oil consumption. Real-time CO2 emissions are calculated based on the real-time power consumption. CO2 emissions calculations and modelling of supply transport units are performed based on previously collected power consumption data from supply transport units. The real-time CO2 emissions for the drilling operations are determined and presented.

Abstract: A method for generating a drilling plan for drilling a wellbore at a field includes receiving data. The data includes one or more of geological properties at the field, wellbore properties, drilling tool parameters, rig characteristics of drilling rigs, and working practices of a plurality of drilling crews. The method also includes generating a plurality of candidate drilling plans for drilling the wellbore at the field. The method also includes estimating one or more outputs for the candidate drilling plans based at least partially upon the data. The one or more outputs include an amount of emissions generated to drill the wellbore using the candidate drilling plans. The method also includes presenting for selection one or more of the candidate drilling plans based at least partially upon the one or more outputs.
