This is a theoretical seismology paper which implements known algorithms for surface wave propagation across single, vertical discontinuities in 2-D media. Seismic surface waves undergo mode conversion at lateral discontinuities and this paper describes a Python software package for accurate computation of these conversion effects, a novel feature not available in the existing seismological literature. This work was done during my PhD research in order to validate a finite-difference wave solver.

Institute of Geophysics and Problems of the Earth Ltd. (Kiev, Ukraine) has developed, patented and been applying in practice for more than 10 years the innovative NMR technology of direct detection of hydrocarbon reservoirs at a depth of up to 5 km without interpretation. Absolute data of deep magтenic resonance sounding are especially in demand during sharp plummeting of oil prices since it significantly reduces exploration risks while saving the exploration budgets of companies.
