The research task presented in the paper covers utilization of computer based method for performance optimization and penetration estimation of shaped charges. The code is used in computer simulations, depicting dynamic non-linear phenomena. This is a perfect tool describing such phenomena as: expansion of detonation products, propagation of shock wave, rapid strains. The LS-DYNA program is used in many scientific and industrial fields, both on an initial stages of product development and on its final stage. The c...

Fracturing using propellant systems is recognized as a cheap alternative to conventional hydraulic fracturing in circumstances where heavy pumping equipment is not available. Usually, fracturing wells with propellants is used as an initial stage, preceding conventional hydraulic fracturing, and to improve the injectivity of the borehole. This method has a number of advantages: the length of the fractures ranges from 1.0 to 5.0 m and it eliminates compatibility problems between the formation fluid and the fracturin...
