Nonlinear Dynamics Methods in Passive Seismic Data Interpretation

H-44 NONLINEAR DYNAMICS METHODS IN PASSIVE SEISMIC DATA INTERPRETATION SERGEY TURUNTAEV Abstract Problem of passive seismic monitoring data interpretation was considered. Ideas and methods developed in the theory of dynamical systems and chaos were used for analysis of productionrelated seismicity at Romashkino oil-field (Russia). Phase portraits of the seismic activity and efficiency of water injection were constructed. Attractor dimensionality and phase space dimensionality were estimated with the help of Grassberger & Procaccia method. 1 Institute for Dynamics of Geospheres Russian Academy of Sciences Leninsky prosp. d.38 k.6 117334 Moscow Russia Introduction There are deformation processes in all parts of the
