One of the most urgent problems of oil and gas reservoir monitoring is the assessment of fractured reservoir infill type — with fluid-filled, gas-filled, or closed (no-reservoir situation) fractures, which is of significant value for time-lapse sei

The Arctic shelf zone is a very important region in our country due to the huge amounts of hydrocarbons, located there. The exploration of this region is difficult because of the presence of lots of various ice constructions, in particular, ice field

The Grid-Characteristic numerical Method (GCM) that is quite common in solving aero and hydrodynamic problems can also be applied for mechanics of solids. It allows to implement complex border and contact conditions, including the non-reflecting bord

An advantage of the discontinuous Galerkin method is the ability to describe complex contact surfaces by using unstructured computational grids. However, the use of the discontinuous Galerkin method requires significant computational resources, inclu

Schoenberg’s mathematical model of fractured geological media has been widely used in studies related to seismic exploration of oil fields. This paper proposes to use this model for computing wave processes in geological media by the grid-character
