| Abstract | ||
| In this research, a qualitative seismic processing and interpretation is made up through using 3D-seismic reflection data of East-Baghdad oil field in the central part of Iraq. We used the new technique, this technique is used for the direct hydrocarbons indicators (DHI) called Amplitude Versus Offset or Angle (AVO or AVA) technique. For this purposes a cube of 3D seismic data (Pre-stack) was chosen in addition to the available data of wells Z-2 and Z-24. These data were processed and interpreted by utilizing the programs of the HRS-9* software where we have studied and analyzed the AVO within Zubair Formation. Many AVO processing operations were carried out which include AVO processing (Pre-conditioning for gathers), AVO modeling and AVO analysis. Analyzing these variations in amplitude within offset or with angle (AVA), reveals the identification of one type of reservoir which is related to the fluid contents and lithology. | ||
