Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional stimulation operations are performed without optimization methods, then the operation can be completed with simple procedures, but the production outcome and fluid recovery are suboptimal
Solution Approach 1:
The patent applies preliminary action by establishing objectives and identifying constraints before the stimulation operation begins. Treatment designs are developed in advance with target fluid distributions determined through simulation, allowing the operation to proceed with pre-optimized parameters rather than reactive adjustments
Solution Approach 2:
The patent implements feedback through real-time monitoring of the stimulation operation and comparing actual results against predicted outcomes. This allows for evaluation of treatment effectiveness and adjustment of operational parameters to optimize production outcomes while managing complexity through systematic control
2Manufacturing precision
If acid treatment is applied without optimized fluid placement strategy, then the treatment can be administered quickly, but the fluid distribution and stimulation effectiveness are suboptimal
Solution Approach 1:
The patent determines target fluid distributions and operational parameters through simulation before the actual treatment. This preliminary design phase establishes the optimal fluid placement strategy in advance, eliminating the need for time-consuming adjustments during the treatment while achieving precise fluid distribution
Solution Approach 2:
The patent employs dynamic adjustment of operational parameters during the stimulation operation based on real-time monitoring. The treatment design allows for flexible modification of pumping rates and fluid injection strategies to maintain optimal fluid placement precision without extending overall treatment time

AI summary
Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.
