1Productivity
If wellbore projectiles are introduced into the wellbore without detection, then the stimulation operation can proceed quickly, but costly and time-consuming remedial operations may be required if the wrong-sized projectiles are introduced
Solution Approach 1:
The optical computing device performs detection of wellbore projectile characteristics before the projectile is introduced into the wellbore. The device captures images or optical signals of the projectile in the flow path, processes them through integrated computational elements, and verifies the projectile's identity, size, and configuration in advance, preventing incorrect projectiles from being deployed
Solution Approach 2:
The patent replaces manual visual inspection or mechanical measurement methods with an optical computing system. The device uses optical fields, integrated computational elements, and image processing algorithms to automatically detect and verify projectile characteristics, eliminating the need for physical measurement tools or human operators to manually verify each projectile
2Device complexity
If manual inspection methods are used to verify projectile size, then equipment complexity is reduced, but measurement precision and reliability of detection are insufficient
Solution Approach 1:
The patent replaces simple mechanical or visual inspection methods with an optical computing system that uses optical fields, integrated computational elements, and digital image processing. This substitution significantly improves measurement precision while keeping the overall device structure relatively simple through the use of compact optical components and integrated circuits
Solution Approach 2:
The optical computing device creates an optical copy or digital representation of the projectile by capturing its image or optical characteristics. This digital copy is then processed through integrated computational elements to verify projectile identity, allowing for precise measurement without requiring complex physical measurement apparatus
3Reliability
If real-time detection of projectile characteristics is implemented, then reliability of stimulation operation is improved, but device complexity and cost increase
Solution Approach 1:
The patent uses optical fields and integrated computational elements to perform real-time detection and verification of projectile characteristics. The optical computing device processes images or optical signals through integrated circuits and algorithms, providing automated real-time verification without requiring complex mechanical measurement systems or multiple separate devices
Solution Approach 2:
The optical computing device is designed to perform multiple functions: capturing optical signals, processing images, verifying projectile identity, and providing real-time feedback. This multi-functional integration reduces the need for separate detection devices and simplifies the overall system architecture while maintaining high reliability
