Proceedings Papers
Publisher: Society of Exploration Geophysicists
Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3563438
... The seismic quality factor, Q , is a critical parameter for seismic data processing and interpretation. Distributed acoustic sensing (DAS) provides a unique acquisition geometry that is ideal for estimating Q . We use a simple twolayer model to generate synthetic DAS data along a vertical well...

Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3592849
... Distributed acoustic sensing (DAS) is an increasingly prevalent technology for seismic acquisition. DAS fibers posses many beneficial properties that make them an attractive candidate for microseismic monitoring, where DAS has experienced an important role. A key task in microseismic monitoring...

Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3583227
... Distributed acoustic sensing (DAS) is increasingly used in hydraulic fracturing operations. The low-frequency band of DAS (LFDAS) contains high-resolution information of the far-field strain perturbations that can be used to constrain fracture geometry. Nevertheless, the interpretation...

Paper presented at the SEG International Exposition and Annual Meeting, October 11–16, 2020
Paper Number: SEG-2020-3426548
... Application of the distributed acoustic sensing (DAS) technique has grown rapidly in geophysics in recent years and enables seismic measurements in restrictive downhole conditions. In downhole hydraulic fracturing operations, the DAS fiber instrumented along the horizontal well can detect...

Paper presented at the SEG International Exposition and Annual Meeting, October 11–16, 2020
Paper Number: SEG-2020-3428141
... Lowering total cost of ownership (TCO) has been a significant driver for adopting distributed acoustic sensing (DAS) over alternative surveillance techniques. For subsea wells, topside DAS requires optical engineering solutions to compensate for the reduced acoustic bandwidth, optical losses...

Paper Number: SEG-2020-3416667
... Inelastic attenuation (or Q ) is typically estimated from vertical seismic profile (VSP) data and has considerable value for surface seismic data processing workflows. For VSP data acquisition, distributed acoustic sensing (DAS) is a cost-effective (and often opportunistic) alternative...
