The symmetry of the expressions for the geometrical spreading and the reflection/transmission loss factor of acoustic waves is investigated for the earth model with smooth reflectors. It is demonstrated that the seismic reciprocity principle holds true for layered earth model.......

Presented are results of laboratory and field study of behavior of mechanically complicated stressed oil-gas-water saturated rocks subject to external physical disturbances. Experimentally established and physically substantiated is a new property of oil-saturated rocks exhibited in the synergetic response of rocks to a static mechanical stress in combination with the elastic wave stimulation.......

On example of the Astrakhan arch fundamental questions of a structure andformation of salt diapirs are considered.......

This paper discusses the problems of detailed thin-layered reservoir studies using estimated pseudo-parameters diagrams obtained -with well logging and seismic data. Detailed reservoir characteristics are accessed using MD fdtering method.......

This paper discusses one of the possible computer simulations of reservoir rocks resistivity using induction logging and several BKZ downhole tools. This technique could be implemented either by generating reservoir models using apparent resistivity curves of the tools (which are free from rock mass resistivity influence), and the assessment of reservoir rock resistivity by excluding the invaded zone influence.......
