Title: Method for seismic monitoring of hydraulic fracturing processes in development of hydrocarbon deposits and heat impact processes in development of high-viscosity hydrocarbons

Abstract: FIELD: measuring. 
     SUBSTANCE: invention relates to a method applied for ground seismic monitoring of hydraulic fracturing of a hydrocarbon layer. In the monitoring mode of the survey, the seismic wave field is continuously recorded from several hours to several days, thereby providing a possibility of estimating the change in the level of microseismic emission. The result of microseismic monitoring is localisation of hypocentres of microseismic events. The claimed method provides a possibility of obtaining a catalogue of located events upon completion of processing. The catalogue comprises the recording time, the coordinates of the located event, the accuracy of selecting the solution in the form of a dimensionless coefficient, and the attributes of the microseismic signal. Further, at the post-processing stage, the obtained catalogues can be imaged in a video format in order to track the changes in the microseismic emission anomalies over time, the observation system is segmented, thus providing a possibility of placing seismometers in areas with a reduced noise load, thereby providing a possibility of increasing the signal-to-noise ratio. 3-component seismic equipment is used in the claimed technique, registering the signal in three directions. The basis of interpretation of the problem consists of the physical process of seismic diffusion (microtremor) caused by changes in the pore pressure. The process occurs both in the petroleum and gas saturated strata development objects and as a result of heat impact on the formation in the process of changing the temperature mode during the development of high-viscosity hydrocarbons. Anomalies reflect the hydrodynamic changes of local and areal nature, therefore the intensity of the anomaly is an integral density value of the recorded events. The method has been tested and has practical application in areas of hydrocarbon layer deposits. 
     EFFECT: increase in the accuracy and informational value of the received data.

Abstract: FIELD: multi-position scanning surveillance systems. 
     SUBSTANCE: invention relates to multi-position scanning systems for observing objects in semi-active and passive modes.

Disclosed method consists in arrangement of several receivers, their mutual orientation in a single coordinate system, receiving signals from objects in them, calculating conjugation indicators of direction vectors to objects and comparing them with a detection threshold, determining estimates of vectors of spatial coordinates and velocities of detected objects. Objects in each scanning period are ranked according to the degree of importance depending on the range and direction of the velocity vector, and the extrapolated position of each object is found in the order of ranking. After that, n receivers antenna lines of sight are switched in direction of extrapolated position, indices of conjugation of vectors of directions to objects located in the zone of visibility of all receivers are calculated, the indices are compared with a detection threshold and estimates of vectors of spatial coordinates and velocities of detected objects are determined. Found estimates are matched with the previously obtained estimates and groups thereof are formed. Likelihood index is calculated for each group, compared with a likelihood threshold, and false groups are discarded. Further, said operations are repeated in a sequence of several survey periods, after which, at the last period, non-overlapping groups are selected from all obtained groups of estimates in order of the likelihood index, number of selected groups is taken as the number of finally detected objects and estimates of these groups – as estimates of trajectory parameters of objects.
