Research Geophysicist with more than twenty years of domestic and international experience. Deep understanding and practical knowledge in geophysics, including working with geological structures, paleochannels and with VSP and HFM data. Also have experience in development and usage of the different processing tools for REVEAL, integrated “Illumination” solution for Repsol, and “Wavefront” solution for Paradigm (part of GeoDepth). Experienced in developing wave separation, semblance deconvolution and noise resistant first brake picking algorithms for VSP. Good working knowledge of Linux, and programming languages C, C++, and Fortran.
- Developed structurally sharpened method extracts and visualizes geological structures, geological objects as paleochannels and highlights structural lineaments from seismic data. - Аnalyze and test the quality and realism of model data and RTM results from 2D and 3D models for machine learning purposes in order to recognize tectonic faults. - Analyze the data processing functionality of "Geoplat Seismic Processing" software. Development of prototypes most needed algorithms required for correct and efficient execution of the seismic data processing steps. - Analyze the data processing functionality of "Geoplat Seismic Processing" software. Development of prototypes that most needed algorithms provided more correct and realistic results of seismic data processing.
Developed geophysical applications for REVEAL: - Picking horizons on the gathers - Resampling seismic data from any float to any float in range 0.001ms – 16 ms - Variable trim static - Surface multiple subtraction in curvelet domain
Design and development of algorithmic and mathematical solutions of “Illumination” based on 3D ray tracing. This product based on 'seismic visibility' approach. Integrated Illumination Solution was developed for Acquisition, Imaging and Exploration Divisions of Repsol and was presented at the Repsol E&P Technical Congress in Madrid on December 2013, EAGE 2015

Fixed and improved Semblance Weighted Deconvolution (Fortran, "QBoreSeis" application, UNIX). Development of algorithmic and mathematical solutions for “WAVE” Work Bench (C#, Windows) of VSP processing: -Adaptive notch filter; -Stacking of VSP raw data with shots and traces quality evaluation by semblances and static shifts adjustment; -Robust 3C transit times picking to noises spikes as spectral as time domain; -Iterative wave separation adjusted for residuals static shifts (using CCF); -Semblance deconvolution with extra options: automatic output BPF, automatic white noise coefficient (all output traces have the same output spectral loading), auto reduction of output harmonic noise; -2D and 3D polarization, relative bearing computation; -Implemented both HFM Orientation shot and DBSeis processing algorithms (BlockFrost ported from Matlab); -Lookup table (P, Sv, Sh) for HFM HORIZON based on 1D VTI model.
Development and design of a travel time calculation algorithm based on ray propagation using the “Wavefront Reconstruction” method for 3D prestack depth migration for anisotropic media. • The “Wavefront” was presented at the annual SEG meeting in San Antonio on September 2001 • Active participated in development and design of travel time calculation algorithms for 3D prestack migration using Fermat techniques in spherical coordinates and Eykonal method in spherical coordinates.
