摘要： Method to monitor reservoir fracture development and its geometry may find its application at oil and gas fields as well as in coal mining industry. The method provides injection of conductive fracturing fluid into the wellbore under pressure enabling to create a fracture in the formation and penetrate into it. At the stage corresponding to the end of the fracturing fluid charging a series of voltage pulses is applied to the fracturing fluid. In the well parameters of the electromagnetic field and/or acoustic signals resulting from applying the voltage pulses to the fracturing fluid are measured, and the fracture tip coordinates are determined.

摘要： Method for determining geometric characteristics of a hydraulic fracture includes performing a baseline seismic survey for a geological formation. A velocity model is created by combining results of the baseline seismic survey and additional geoscientific information, and seismic properties of the geologic formation are evaluated. At least one strong flat lithological reflector disposed below a planned fracture is identified. A numerical model of elastic wave propagation in the geologic formation with a fracture with given properties is created. Hydraulic fracturing is performed and after fracturing when the fracture is maintained open and pressurized seismic surveys are performed. The fracture's dimensions and shape are determined by comparing the first and the second reflected and refracted seismic signals and solving an inverse problem with the use of the numerical model.

摘要： The invention concerns a method for determining the position, in a formation (1) containing at least one electrolytic liquid, of an interface (6) in relation to a bore hole (2). One stimulates at a first instant the interface (6) with an excitation signal, one detects at a second instant (t2) a response signal converted by electro-osmosis or electrokinetic coupling effect and, if appropriate, the exication signal after reflection at a third instant (t3). With the three instants and the propagation velocity of the signals, one calculates the distance between the interface (6) and the bore hole (2).

摘要： The invention relates to the methods for determining the permeability of a geological formation saturated with a liquid and provides for a method, a system and a logging tool for estimating permeability. The method comprises exciting a formation with acoustic energy pulses propagating into the formation, measuring the acoustic response signals produced by the acoustic exciting and the electromagnetic signals produced by said acoustic energy pulses within the formation and separating components from said measured acoustic response signals and said measured electromagnetic signals representing Stoneley waves propagating through the formation. The acoustic response signals and electromagnetic signals representing Stoneley waves propagating through the formation are synthesized. The separated acoustic response signal and electromagnetic signal components and the synthesized Stoneley wave signals are compared. The permeability is determined from differences between the synthesized Stoneley wave signals and the separated acoustic response signal and electromagnetic signal components.
