The In the December 2016 SE University Session, Structural Irregularities per the ASCE7-10 Seismic Design Requirements, Kimberley Robinson, PE, SE, from SunSteel LLC, presented a helpful flowchart to determine the permitted analysis procedure based on a structure’s seismic design category, height, and structural irregularities. Mention the word “geometry” and people think about shapes and angles, and maybe the time they outsmarted an opponent on the pool table. Seismic data are usually contaminated with two common types of noise, namely random and coherence. • Well data.Well data are gotten from rock samples and measurements at depth from a wellbore. 2. Clipping is a handy way to collect important slides you want to go back to later. Deconvolution often improves temporal resolution by collapsing the seismic wavelet to approximately a spike and suppressing reverberations on some field data (Figure I-7). This basic sequence now is described to gain an overall understanding of each step. The aim of the study is to improve the chirp seismic data quality by using two processing methods, to get more interpretable chirp data. 3. Thus, when entering the field data, the name line 1 - raw was selected here. Commonly, seismic data processing procedures, such as stacking and prestack migration, require the ability to detect bad traces/shots and restore or replace them by interpolation, particularly when the seismic observations are noisy or there are malfunctioned components in the recording system.
