- W4384693144 abstract "Background: Well tying is an integral part of seismic interpretation both at the stage of structural and dynamic analysis. Linking seismic and well data is a critical process that allows you to link geological objects identified from seismic data with actual data obtained from wells, because. it is based on the relationship between the lithological composition of the deposits that make up the section under study and the characteristics of the reflections. Seismic data are in most cases presented on a time scale, while well data are on a depth scale, and in order to calibrate them, it is necessary to select a velocity law and establish a time-depth relationship.
 Aim: This article aims to deepen the understanding of the importance of quality control of initial well data to improve the result of seismic stratigraphic tying and increase the efficiency of geological exploration, as well as to propose methods to improve the quality and efficiency of tying..
 Materials and methods: Methods for correcting the readings of acoustic logging are described, various algorithms for tying seismic and well data are given.
 Results: The paper considers the reasons for the distortion of the values of the initial well data, examples of data quality analysis, suggests options for how to conduct a seismic stratigraphic tie in the conditions of a limited or initially substandard set of initial data and obtain reliable depth-velocity dependences for wells.
 Conclusion: Conducting quality control and, if necessary, correcting the original well data is a critical step to improve the accuracy of the final results of seismic interpretation. It is important to note that even with limited and low quality input data, it is possible to obtain depth-time dependencies. However, the results of the work show that editing and amending the original logs significantly improve the quality and detail of the seismic stratigraphic tie." @default.
