Beschreibung
Zusammenfassung:	FIELD: mining. ^ SUBSTANCE: invention relates to a method and a device for determining the shape of hydraulic fracture cracks in rocks. To this end said method and said device provide for injecting a fluid into one or more wells under a pressure, which allows said fluid to create cracks and to penetrate through them into rock surrounding the wells, whereby electric and magnetic fields are established and then measured inside the well. The shapes of the cracks are determined using values of the measured fields in their functional relationship to the location and time of measuring. ^ EFFECT: providing a method and a device for determining the shapes of cracks in rocks surrounding oil wells. ^ 11 cl, 11 dwg
