Paper presented at the SEG/AAPG International Meeting for Applied Geoscience & Energy, August 26–29, 2024
Paper Number: SEG-2024-4093246
... There are problems with inconsistent seismic wavelets and geophone coupling in uphole survey data, which can reduce the accuracy of near-surface Q value. Firstly, conduct three amplitude spectrum ratio calculations on four uphole survey data from two shooting points and two receiving points...

... needs to be automatic and in real-time. For the latter requirement, processing workflows using 3-component (3C) downhole geophones have been established in the industry for years, mainly for short-term monitoring, e.g. for hydraulic fracturing. With the increasing interest in CO2 sequestration...

... the derived angles. Using the recovered amplitudes, we generate horizontal and vertical hodograms that are comparable to those of a 3C geophone at the DAS array center (x=0, y=0). Our DTT and waveform modeling results show that a 3D optimally distributed fiber cable can effectively acquire 3C DAS array data...
