AbstractIn order to consider of the need to perform further timely & costly 3D surveys or even to drill a risky exploration well, we have to maximize all information extraction from existing 2D seismic data which is at the early stage of any exploration. For getting information from seismic data I applied 2D AVO/AVA forward modeling, analysis and evaluation steps to the public field dataset. The objective of this study is to predict how the fluids laterally saturate the interested reservoir on the 2D seismic section. For the objective I tried to develop a workflow of 2D AVO/AVA forward modeling and to verify the workflow with a public field dataset for the applicability and effectiveness of the workflow. In this study I applied the workflow to a public dataset from Enfield oil field in Australia, where mainly oil with some gas and water had been produced from the reservoir. From the interpretation of the results, a discussion was made about the potential applicability of this workflow in terms of predicting the possible fluid saturated in the reservoir away from the control well. From these results, the higher confident recommendation for the next well's locations could be made. Since this methodology was aimed to imply for the immature exploration field where limited information is available, results of this research would be only considered as a qualitative interpretation and predictive answer for the explore-or-not consideration and decision. However, based on this meaningful outcome, a lot of further works, such as demanding quantitative reservoir characterization or seismic inversion, would easily attract our attentions as soon as 3D survey becomes available.
