| الوصف: | Three-dimensional frequency-domain full waveform inversion (FWI) of fixed-spread data can be efficiently performed in the visco-acoustic approximation when seismic modeling is based on a sparse direct solver. We present a parallel algebraic Block Low-Rank (BLR) multifrontal solver which provides an approximate solution of the time-harmonic wave equation with a reduced operation count, memory demand, and volume of communication relative to the full-rank solver. We analyze the parallel efficiency and the accuracy of the solver with a realistic FWI case study from the Valhall oil field. |
