Processing Flow. The pressure signature from a water gun has pressure variations (a precursor) before the main pressure pulse. This chapter represents a brief introduction to seismic data processing and provides a conventional processing flow for marine seismic data. Andrea Lovatini explains the benefits of integrating seismic and nonseismic methods. A specific area might receive hundreds or thousands of blasts over a predetermined period of time. Seismic surveys EOSYS carries out conventional or very high resolution land and marine reflexion seismic data acquisition campaigns, using sources of all types (dynamite, weight drop, vibratory or marine sources). The USGS Coastal/Marine Hazards and Resources Program is a leader in the acquisition, processing, and interpretation of high-resolution seismic data collected in the open ocean, on the continental shelf, and in estuaries, lakes, canals, and rivers. Data processing methods The processing sequences are started by de multiplexing the field data, then processing the data to obtain seismic cross section free from noise and multiple so that result can be analyzed and interpreted. A processing flow is a collection of processing routines strung together and applied to a data volume. Stay connected—Remember to update your registration information.

Martin Bayly Ng Swee Leng . Learn how early understanding of subsurface challenges can save time and costs. Because the multiple wave has a certain regularity and cyclicality in time, and predictive deconvolution has an application parameter with relatively definite physical meaning, namely predictive step, using the predictive deconvolution can effectively attenuate the multiple wave. This correction is in the form of a vertical time shift to a flat datum and is known as a statics correction , but will need further correcting later in the processing sequence because the velocity of the near-surface is not accurately known. Products. It is aimed to identify any problems with seismic acquisition at the very same moment when they happen.
