Abstract Shear-wave splitting (SWS), or the propagation of two independent shear waves, can be used as an indicator seismic anisotropy. In this study, we utilize concept using aftershock data 2018 Lombok earthquake which had been acquired in period August 4 – September 9, 2018. The goal research is to better understand crack distribution related rupture zone earthquake. After applying instrumen...

We propose a modification to the Non-linear Asymptotic Coupling Theory (NACT), a normal mode coupling method used for synthesizing seismograms and computing sensitivity kernels in 3D Earth. The modification is aimed to meet the computational challenges for NACT when approaching higher frequencies, which is required for obtaining finer scale images of the Earth's upper mantle. The new scheme is ...

A considerable effort has been made in the literature for quality assurance (QA) and checking (QC) of petrophysical log data computation reservoir rock property parameters. Well plays an integral role building a physics model quantitative interpretation (QI) work. poor-quality may lead to significant financial HSSE implications by drilling wells undesired locations. Historically, variety techni...
