FIELD Processing OF Seismic DATA

(Service)
Online Support Service: No
Interpretation of Data: No
Description:
Geophysical information goes through a full cycle of standard and in-depth processing of seismic data. Processing of field seismic information is carried out in specialized laboratories and centers equipped with computer workstations and high-power servers.
Overview:

Field VCs directly at the place of work allow for the correction of the production process, in the case of substandard data. The presence of a field CC for further processing and interpretation of seismic data is the key to obtaining high-quality primary material.

Quality control of field work in a batch is carried out at all stages:

  • quality control of topographic and geodetic works (accuracy of binding and installation of PV and PP, quality of preparation of seismic profiles);
  • quality control of the source of excitation (accuracy of its location, depth of charge, quality of capping, fullness of the explosion);
  • control of the registration system (reception arrangement and recording equipment);
  • quality control of field primary materials;
  • pre-processing of data on the field CC;
  • All materials are collected in a single field database and are subsequently used for processing.

Field processing of seismic data includes the following processing procedures.
(finally the processing graph is determined after experimental work):

  • conversion to internal format;
  • geometry input;
  • geometry control;
  • edition of defective traces;
  • amplitude recovery;
  • entering static corrections;
  • corrective filtering;
  • CDP summation;
  • speed analysis;
  • correction of static corrections;
  • summation;
  • band pass filtering;
  • output on paper of temporary cuts.

Since the quality of the field work will inevitably affect the final results of the project as a whole, Udmurtneftegeofizika LLC takes responsibility for solving the general task of improving the quality of projects and processing seismic data.
