Description:
<jats:p>Fiber-optic sensing (FOS) are an emerging technology in hydraulic fracture diagnosis. Fiber-optic sensing technologies mainly include distributed temperature sensing (DTS) and distributed sound sensing (DAS). During hydraulic fracturing, the perforation cluster efficiency for cemented plug and perforation (PnP) wells, points of fracture initiation for packer and sleeve (PnS), and fluid channelling between fractured intervals caused by either tubular or annular leaks could be quantitatively evaluated by DTS data. Combined with DAS data, fluid distributions for each fracturing stage along the entire horizontal wellbore could be obtained. The roles of DTS and DAS in different hydraulic fracture stages are comprehensively analyzed in this paper. It provides a guidance for application of FOs in oil industry.</jats:p>
