Seismic anisotropy in siliciclastic reservoir rocks [PDF]

, 2006
The interpretation of geophysical field measurements of seismic anisotropy is presently limited by our knowledge of the controls of the elastic anisotropy of sedimentary rocks in the subsurface. Traditionally, laboratory ultrasonic velocity measurements

Noise fault analysis of FHD proton vector magnetometer：Taking Suqian geomagnetic station as an example

地震科学进展, 2023
In this paper we analyzed the increased noise in the observation data of FHD proton vector magnetometer at Suqian station from April 28, 2020. After we checked and analyzed the instrument parameter settings, observation environment, instrument and ...

Deep-learning inversion: a next generation seismic velocity-model building method [PDF]

Geophysics, 2019
Seismic velocity is one of the most important parameters used in seismic exploration. Accurate velocity models are the key prerequisites for reverse time migration and other high-resolution seismic imaging techniques.

Analysis and treatment of common faults in seismic station computers

地震科学进展, 2022
Taking the computer of seismic station as the object of discussion, the causes of “system crash” “automatic shutdown” “blue screen” and other faults that frequently occur in the computer at the precursor site area are analyzed and studied. Reasonable and

Fast Holocene slip and localized strain along the Liquiñe-Ofqui strike-slip fault system, Chile

Scientific Reports, 2021
In active tectonic settings dominated by strike-slip kinematics, slip partitioning across subparallel faults is a common feature; therefore, assessing the degree of partitioning and strain localization is paramount for seismic hazard assessments.
