INSTANTANEOUS ISOCHRON ATTRIBUTE-BASED GEOBODY IDENTIFICATION FOR RESERVOIR MODELING |
摘要 |
Automated systems and methods that provide robust identification of regions of interest for reservoir modeling are disclosed herein. One embodiment includes: obtaining a seismic image of a subsurface region; performing full-volume horizon picking and deriving an instantaneous isochron attribute (IIA) value for each point in the seismic image; identifying one or more geobodies within the seismic image based at least in part on the IIA values; and representing the one or more geobodies in a geocellular model. The identifying of geobodies may include: applying IIA value filtering to isolate intervals of rapid or slow deposition in the seismic image; determining a reservoir-non-reservoir indicator attribute value for each point in the seismic image; applying reservoir-non-reservoir indicator value filtering to isolate subintervals of presumed reservoirs or non-reservoirs in said isolated intervals; determining a pay indicator attribute value for each point in the seismic image; and applying pay indicator value filtering to isolate presumed pay zones in said isolated subintervals. |
