Abstract

Summary

Modern methods of borehole seismic studies create new opportunities for studying strata. A new technology in this area is distributed acoustic sensing (DAS), the principle of which is to use an optical fiber as a sensor for measuring seismic signals over the entire fiber length with high spatial resolution. During field studies at an operating well using DAS technology, an experimental recording of seismic signals was performed to investigate the processes occurring in the well. The results of this work allow us to judge the large potential of fiber-optic sensors for use in seismic data acquisition. The use of such systems will make it possible to raise the information content of all types of well seismic observations qualitatively, to monitor the hydraulic fracturing and to monitor extracting of hydrocarbons. In addition to increasing the quantity, quality and informativeness of the received data, this technology simultaneously will reduce the cost of operations.
