Autor: Marina G. Persova, Yuri G. Soloveichik, Denis V. Vagin, Anastasia P. Sivenkova, Anna S. Kiseleva, Dmitry S. Kiselev, Marina G. Tokareva

Publikováno v: Journal of Environmental and Engineering Geophysics. 27:23-32

We present two approaches to solving the airborne electromagnetic (AEM) problems given the induced polarization (IP) effect: with calculating the field in a polarizable medium directly in the time domain (TD) and with calculating the EM+IP field in t

Autor: Dmitry S. Kiselev, Marina G. Persova, Alexander M. Grif, Anastasia P. Sivenkova, Yuri G. Soloveichik, Denis V. Vagin

Publikováno v: Computational Geosciences. 25:1957-1981

We consider aspects that can significantly increase the computational efficiency of solving multisource 3-D problems of airborne electromagnetic prospecting in complex geological media. An approach to fully automatic construction of non-conforming he

Three‐dimensional inversion of airborne data with applications for detecting elongated subvertical bodies overlapped by an inhomogeneous conductive layer with topography

Autor: Dmitry S. Kiselev, Yuri G. Soloveichik, Denis V. Vagin, Marina G. Persova, Alexander M. Grif, Yulia I. Koshkina, Anastasia P. Sivenkova

Publikováno v: Geophysical Prospecting. 68:2217-2253

We propose the approach to 3D inversion of airborne electromagnetic data, which is intended for discovering subvertical bodies overlapped by essentially inhomogeneous conductive layers. The approach is based on the geometric inversion in which a geoe

Analysis of the polymer flooding efficiency in one of the high-viscosity oil fields based on mathematical modeling

Autor: Dmitry S. Kiselev, A.S. Ovchinnikova, Yu.G. Soloveichik, Marina G. Persova, Ilya I. Patrushev

Publikováno v: Geomodel 2021.

Summary The paper presents the results of modeling polymer flooding in a high-viscosity oil field in various modes. For modeling, a multilayer laterally heterogeneous reservoir model was used. This model was obtained as a result of automatic history
