AI Technical Summary

Benefits of technology

This patented technology allows for better understanding of how oil or gas develops within an area during drilling operations compared to previous methods such as vertically drilled boreholes. It simplifies the process of optimizing hydrocarbon production from subterranean formations while maintaining their integrity through optimal placement of certain types of equipment used downhole (such as pipelines). Overall this innovation improves efficiency and performance predictive analysis on both exploration-based and mineral resource extraction projects.

Problems solved by technology

The current methods discussed by this patents involve optimally developing horizontals with specific features such as fluid velocity or permeabilities. However, these techniques may be limited due to their limitations related to coupling mechanisms among different components within the borehole system during exploration operations. This limitation can lead to poor performance results when trying to optimize certain aspects like water injection into subterranean formations.
