3D Basin Modeling - A New Tool for Petroleum SystemAnalysis

摘要

2.5 D basin modeling, pseudo 3D modeling or Map View modeling is today usedextensively in the oil industry for prospect evaluation and appraisal. Most of these tools are strictlydetermininstic, while the uncertainties in many of the input parameters require stochastic modelingtechniques. These pseudo 3D models are frequently linked with simplified fluid flow simulators basedon ray tracing or percolation. The use of 3D basin simulators as an exploration tool has been limited bythe trade off between computing times and geologically realistic grid sizes. The paper outlines some ofthe ways around this and our experience in this field. With increasing use of 3D seismic in anexploration phase it is important to develop 3D basin modeling tools that can utilize these data in a costeffective way.
