Geophysical Modeling of Subsurface Volumes Based on Horizon Extraction

摘要

Method and system is described for modeling one or more geophysical properties of a subsurface volume. The method includes extracting locations from the data volume and combining them into an object, for example a horizon. The extraction may begin with selecting one or more initial traces, assigning labels to each sample of each trace, selecting a propagation pattern, and propagating the labels from the initial traces along a vector volume. Then, locations with the same label are extracted (1106). As an alternative to label propagation, a specific type of labeled volume (1102) may be obtained, such as a stack of surfaces (1132). The object may then be further modified or utilized to enhance the process of producing hydrocarbons.
