Geophysical model construction of fractured reservoir by means of seismic data

Over several decades the meaning of fractured reservoirs in exploration geophysics is increasing steadily. Detection of fractured zones and estimation of its parameters became necessary stages of seismic interpretation. Essential difficulties during the determination of the model are associated with uncertainty of seismic interpretation and low resistance of estimated parameters. The approach, concerned with model selection and methodology of seismic interpretation, plays the key role, taking into account the facts, mentioned above. The main purpose of the article is to detect diagnostic features and physical proprieties of fractured reservoirs; it can help to construct effective model of reservoir and to avoid wrong alternative methods of seismic interpretation.
Materials and methods
Effective-medium theory, seismic inversion.
Results
The algorithmic basis of INPRES software complex is described in the article. The interpretational complex INPRES is intended for the detection of fractured zones and estimation of its physical parameters, according to azimuthal variations of seismic characteristics. Results of seismic interpretation are demonstrated.
Сonclusions
The most relevant variation of interpretation among the three afore-mentioned (failure of fracturing forecast; interpretation, based only on seismic data; forecast, controlled with mathematical modeling of seismic effis the third variation, when there is enough geological and geophysical information for the forecast.
