Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional drilling plans are used without emissions consideration, then drilling operations can proceed with simpler planning, but emissions are not minimized and environmental impact increases
Solution Approach 1:
The system performs preliminary emissions estimation and optimization during the drilling plan generation phase, before actual drilling operations begin. By calculating emissions for multiple candidate plans in advance and selecting the optimized plan, the system prevents harmful emissions without adding operational complexity during execution.
Solution Approach 2:
The system creates virtual copies of drilling plans through simulation to evaluate emissions without executing actual drilling operations. By modeling and comparing multiple candidate plans in a virtual environment, the system identifies the lowest-emission option before implementation, resolving the contradiction between emissions reduction and planning complexity.
2Object-generated harmful factors
If multiple candidate drilling plans are simulated and compared, then emissions can be minimized, but computational time and processing resources increase
Solution Approach 1:
The system generates multiple candidate drilling plans beyond what is strictly necessary, then selects the optimal one based on emissions criteria. By creating a larger set of candidate plans with varying characteristics, the system ensures finding the lowest-emission option without requiring exhaustive analysis of every possible variation, balancing thoroughness with efficiency.
Solution Approach 2:
The system varies key parameters across multiple candidate drilling plans (such as drilling speed, tool selection, sequence of operations) to create diversity in emissions profiles. By systematically changing parameters in candidate plans, the system efficiently identifies the optimal plan with minimal emissions without requiring complete exploration of all possible plan variations.
3Object-generated harmful factors
If drilling plans optimize for emissions reduction, then environmental impact decreases, but drilling time and cost may increase
Solution Approach 1:
The system adjusts operational parameters across multiple candidate plans to find the optimal balance between emissions and productivity. By varying parameters such as drilling speed, tool selection, and operational sequences, the system identifies plans that reduce emissions without excessive sacrifice of drilling speed or time, achieving a balanced optimization rather than extreme emission reduction.
Solution Approach 2:
The system evaluates multiple candidate plans based on both emissions and productivity metrics, then selects the plan that achieves the best overall balance. By considering both emissions and productivity in the selection criteria, the system ensures that emission reduction does not come at the expense of excessive time or cost increases, maintaining productive efficiency while reducing environmental impact.

AI summary
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.
