METHOD OF ESTIMATION OF RUPTURE GEOMETRY; COMPOSITIONS AND ITEMS USED FOR THIS PURPOSE Russian patent published in 2010 - IPC E21B49/00 G01V3/08 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to hydraulic break of underground reservoirs required, for example for stimulation of oil or gas inflow into well. The method consists in the below described operations: a particle-target and/or propping agent are introduced into a rupture; further, electromagnetic radiation of from approximately 300 MHz to approximately 100 MHz frequency is emitted into the rupture; a reflected signal from the particle-target is analysed for estimation of rupture geometry. Here is also disclosed the method of estimation of underground rupture geometry including operations, where: the target and/or propping agent are introduced into the rupture; also the particle-target and/or propping agent contain high dielectric ceramic with dielectric constant more or equal approximately to 2; electromagnetic radiation of frequency less or equal to approximately 3 GHz is emitted into the rupture; signal reflected from the particle-target and/or propping agent is analysed for estimation of rupture geometry.

EFFECT: ensuring increased reliability and safety of estimation of rupture geometry of hydraulic break, decreased expenditures for this operation.
