Proposed is a technology of Seismic Location of Emission Centers (SLEC) – a new modification of passive seismic monitoring of processes taking place in reservoirs in course of production. SLEC technology features the use of standard seismic equipment for the surface acquisition of seismic wavefield and application of “Slionkin Focusing Transform” (SFT) which provides high spatial selection (focusing), noise immunity, and prompt interactive processing of results of seismic observations. Presented are results of industrial testing of the SLEC technology for monitoring hydrofracturing operations, fluid injection performed to maintain the formation pressure and natural fluid dynamics in reservoir during production.
