In the past few decades it has been evident that various human activities can induce local seismic activity. One of the important factors of human induced seismicity is hydrocarbon fields? development [6], [12]. One of the regions with probable induced seismicity is Tatarstan Republic where a giant Romashkino oilfield has been produced for a several decades. The link between seismicity and hydrocarbon production for this area was previously studied [1]. In this study the attempt has been made to find possible refl...

As a rule, well-log porosity is used as a reference information in the process of reservoir porosity model construction. At the same time, the regions of the model, where the porosity values are obtained by interpolating the well data, are characterized by a decrease in detail with distance from the wells, as well as by uncertainty in the interwell space. The uncertainty arising from interpolation can be significantly reduced as a result of the integrated use of well logging and 3D seismic data, and the usefulness...

Seismic sources location is one of the main tasks of seismology (determination of earthquake hypocenters) and this is the main task in microseismic monitoring of hydraulic fracturing. When choosing a method for microseismic monitoring, noise immunity is one of the main parameters, which should be considered in order to obtain reliable results. The article is referred to the location of a point seismic source by the Diffraction Stacking method applied to synthetic signals obtained using 2D numerical simulation of s...
