EVALUATION OF REPRESENTATIVITY OF SEISMIC EVENTS CATALOGUE OF ORENBURG REGION

Abstract

The paper describes the analytical processing of catalogues of seismic events instrumentally registered in hydrocarbon deposits of Orenburg region by Neftegaz-seismic network. The representativity of seismic data catalogues is evaluated using the commonly accepted method of allocation of a linear segment in dependence of the logarithm of the
number of seismic events having the prescribed magnitude to the magnitude or the angle of inclination of the recurrence graph. As a result, the refined and preliminary indicator of the magnitude of tectonic stresses respectively for Orenburgskoe and Baituganskoe hydrocarbon deposits has been obtained.
