Fracture-Stimulation Placement With Fiber-Optic Distributed-Sensing Diagnostics

摘要

The connection of the wellbore to hydrocarbon-resource volumes by effective fracture stimulation is a critical factor in unconventional-reservoir completions. This paper provides some insights into the effectiveness of the hydraulic-fracture -stimulation (HFS) process with fiber optics (FO), distributed acoustic sensing (DAS), and distributed temperature sensing (DTS). The paper discusses multiple wells where FO has been used to gain a better understanding of three highly debated fracture -stimulation- distribution topics: diversion, stage isolation, and overflushing.
