Summary:
Seismic data has long been successfully used in building of reservoir models. Building of a structural framework, sequence- and seismic stratigraphy interpretation as well as reservoir properties characterization in the interwell space are common seismic "specialties". In recent years, a new direction in the use of seismic data is actively developing – that is, in geomechanical model building. Geomechanical factors play an important role at all stages of the life of a field. As a result, there is a need to assess and manage them, starting with a forecast of drilling risks and ending with a maximization of production. Geomechanical models are vital in well planning in the sense of forecasting possible drilling problems. Wellbore stability, combined with the pore pressure determines restrictions on mud weight required for secure drilling. Reliable geomechanical model is ultimately needed while planning hydraulic fracturing in order to intensify production of hydrocarbons. Exploration for hydrocarbons in complex reservoirs and difficult conditions, as well as their further development requires improved and innovative approaches. In this regard, efficient use of seismic data in building of geomechanical models is very important.
