An apparatus for generating signals and energy for transmission to a large mass (17). The apparatus incorporates a pulsed generator (10) such as a compensated pulsed alternator for storing and for discharging large amounts of energy in a controlled manner for transmission through a vibrator or similar electromechanical device. In the field of seismic exploration, the apparatus discharges seismic source energy into a land mass or water to generate seismic waves which are reflected from the interface between subsurface geologic formations. The pulsed generator (10) permits the seismic source energy to be discharged in a controlled manner to shape the energy signal, and permits large quantities of energy to be discharged to increase the penetration depth and strength of the reflected signals.

The invention relates to the oil-gas production industry and can be used for stimulating wells by increasing the permeability thereof. The inventive method consists in supplying an acid in an inactive form to a formation. Said invention is characterised in that titanium chloride hydrates having the general formula TiCl4 nH2O, wherein n=1.5-2.5, are used as an acid in an inactive form. Said hydrates have a crystalline structure with bulk density of 1.1 g/cm3 and the content of active chlorine hydrate ranging from 56 to 60 %. Said invention makes it possible to extend the radius of the zone of penetration of the acid into the formation matrix, thereby increasing the penetration of the formation and the efficiency of the treatment of a bottom-hole formation zone.
