Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3867722-MS
... on the frequency shifts of the Rayleigh backscattered spectrum, which is sensitive to temperature and mechanical strain changes. This work uses in-well RFS-based DSS and DTS measurements acquired during a single-stage stimulation. The goal is to quantify the mechanical strain changes by removing the temperature...
