Algorithm for determining inclusion parameters in solving inverse problems of geoelectrical exploration using the profiling method

The paper aims to develop an algorithm for recognizing the physical and geometric parameters of inclusion, using indirect methods of boundary, near-boundary, and partially-boundary elements based on the data of the potential field. Methodology. The direct and inverse two-dimensional problems of the potential theory concerning geophysics were solved when modeling the earth's crust with a piecewise-homogeneous half-plane composed of a containing medium and inclusion that are an ideal contact.

The recursive method for the solution of dynamical seismic problems for a domain with irregular surfaces

2-D dynamic problem is considered. The source of seismic waves is modeled by shear dislocation. The medium studied is modeled by the system of plain homogeneous and isotropic layers separated by irregular interfaces. The direct problem solution is obtained and the equation for determining the shape of the interface.

Using the kinematic and dynamic propagators for obtaining the approximate solution of direct dynamic problem of seismic exploration

An effective algorithm is suggested for obtaining the approximate solution of direct dynamic problem of seismic exploration, using a theory of kinematic and dynamic propagators. The developed algorithm has been included as a subsystems in automated system of quantitative complex interpretation of geologic and geophysical data GCIS. The modeling experiment has shown the adequacy and efficiency of the solution as was compared to traditional grid method of solving the direct dynamic problems.
