Seismotech, Ltd. presented several reports at the Conference “Geomodel-2021. 23rd Scientific and Practical Conference on Geological Exploration and Development of Oil and Gas Fields" on September 06-10, 2021 in Gelendzhik, Russia.
Within the Conference "Geomodel-2021" we presented the following reports:
1. "Uncertainty analysis of reservoir geometry by multivariate tomography"
Anisimov Ruslan, Leading Software Developer
Seismic tomography today is one of the main tools for obtaining a velocity-depth model. Its result determines the structural component of the resulting reservoir model. Tomography is a deterministic procedure and does not provide an opportunity to estimate the reliability of the results. But in fact, subsequent economic decisions about production of oil and gas fields directly depends from results obtained on analysis of seismic images. According to this reason, the main objective of the report is to provide a method of multivariate tomography for quantification of the uncertainty of resulting reservoir geometry. Also we demonstrate the results of application at real project.
2. "Wavefield modeling in seismic data processing"
Ovchinnikov Kirill, Geophysicist
Modeling of wave fields belongs to one of the oldest tasks of seismic exploration, so there are quite a few methods of modeling. It is impossible to cover all methods of solving direct problems and their applications within the thesis, so here we will list the main ones and separately dwell on modeling based on the method of inverse migration transformation. In addition, examples will be given of the application of model fields in solving current problems of seismic data processing (and interpretation).
3. "Seismic survey method with vibroseis source"
Finikov Dmitry, the Head of R&D Department
Shalashnikov Andrey, Leading Software Developer
The report describes a seismic survey method with several significantly different sweep signals. This difference may lie in their duration at an identical frequency range. It is argued that under these conditions it is possible to identify the differences between the signals that actually went into the medium and the projected ones. Illustrations of the method on model examples are given.
