... anomalies and errors in the horizon picking or isochrone mapping. These problems determine relatively high structural uncertainty, in comparison with the anticline size. This uncertainty was systematically underestimated before drilling. In archival seismic interpretation reports the estimated accuracy was often too high, and prognostic standard error was too low. Moreover, the geometrical size of prospects was often overestimated, that was the reason for evaluated hydrocarbon resources beingtoo ...

... геолого-геофизической скважинной информации. 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 ...
