Abstract

Distinguishable amplitude phenomena on surface seismic data often resulted from contrasts in the elastic parameters of subsurface layers. Various techniques have been involved to analyze and highlight such phenomena for their potential use as "Direct Hydrocarbon Indicator (DHI)". More recently, other techniques have been developed based on the variation of reflection coefficient with angle of incidence, conventionally called Amplitude-Versus-Offset (AVO).During the last twenty years the significance of AVO analysis for studying seismic reflection in oil exploration has been considered more importantly. In this work, first, a seismic line from a gas field and also a well are selected to indicate the results of the application of AVO analysis for detection of hydrocarbon reservoir in this field.In this project, using well logs and information obtained by core analysis, a SYNTHETIC SEISMOGRAM has been built applying Zoeppritz equation. And Using Hampson-Russell software, AVO ATTRIBUTEs have been extracted from SYNTHETIC SEISMOGRAM. Then anomalies of these ATTRIBUTEs have been investigated and compared with the anomalies from AVO ATTRIBUTEs which were extracted from real seismic data to characterize the reservoir.It has been seen that the extracted ATTRIBUTEs of the SYNTHETIC SEISMOGRAM confirm the anomalies from real seismic data. Finally according to the obtained result, observed anomalies can be interpreted as a Gas Cap for this reservoir. This study is useful to identify reservoir and nonreservoirs and the results of this study are considered as input for detailed reservoir studies. In particular, knowing the reservoir physical and saturating fluid properties is of great importance in making plans for developing the reservoir.
