Well Plan Validation System for Multi-Candidate Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Planning activities in the energy industry, such as well drilling, often require input from multiple experts, leading to challenges in tracking and validating decisions across different domains, and evaluating the impact of various approaches on the final plan, especially when considering multiple candidate solutions.
Innovation Solution
A computer-implemented method that receives an initial well plan, allows users to create alternate plans, executes validation routines to calculate estimated time and cost, and displays these for comparison, enabling users to select a master plan, store differences, and log changes, while also calculating emissions footprint and risk profiles.

Engineering Contradiction Analysis
1Reliability
If multiple candidate well plans are created and evaluated, then the quality of decision-making is improved, but the time and computational resources required increase
Solution Approach 1:
The system performs preliminary validation and estimation calculations during the plan creation phase rather than waiting until all plans are complete. This allows early identification of problematic plans and reduces the time needed for final evaluation by pre-computing key metrics like estimated time, cost, emissions footprint, and risk profile for each candidate plan.
Solution Approach 2:
The system creates multiple candidate well plans by copying and modifying a base plan, allowing rapid generation of alternatives. Each copied plan can be independently validated and compared, enabling efficient evaluation of multiple scenarios without creating entirely new plans from scratch each time.
2Measurement precision
If comprehensive validation routines are executed on alternate well plans, then the accuracy of plan assessment is improved, but the computational complexity increases
Solution Approach 1:
The validation process is divided into multiple independent routines that assess different aspects of the well plan separately (time estimation, cost calculation, emissions footprint, risk profile). Each validation routine operates independently and can be executed in parallel, making the complex validation process more manageable and efficient.
Solution Approach 2:
The validation system uses a universal framework that applies the same multi-criteria assessment approach to all candidate well plans regardless of their specific characteristics. This standardized validation process ensures consistent and accurate comparison across different plans while reducing the complexity of creating plan-specific validation logic.
3Productivity
If multiple alternate well plans are generated and compared, then the ability to identify optimal solutions is improved, but the difficulty of managing and comparing plans increases
Solution Approach 1:
The system provides automated feedback by comparing each alternate well plan against the initial plan and against each other across multiple criteria (time, cost, emissions, risk). This feedback mechanism highlights the differences and relative merits of each plan, making it easier for users to identify the optimal solution without manually analyzing each plan in detail.
Solution Approach 2:
The system introduces an intermediary comparison framework that mediates between multiple candidate plans and the decision-maker. This framework automatically synthesizes the results from multiple validation routines and presents a consolidated view of how each plan performs across all evaluation criteria, simplifying the complex task of comparing multiple alternatives.

AI summary
An improved approach to creating a plan for a well. A user receives an initial well plan for a planned well and uses the initial well plan as a starting point for alternate well plans. This is done by creating a copy of the initial well plan, allowing the various uses to make changes to the initial well plan, and executing various automatic validation routines on the alternate designs. These validation routines can provide estimated times and costs to complete the planned well use the alternate well plan. The approach can also involved displaying the estimated times and costs of the different candidate well plans. The user can then select one of the candidate well plans as the master well plan. As replanning is done during the operations, this replanning information, along with the actual executed actions, is captured and stored.
