Abstract
In this contribution we present a methodology for structural analysis of seismically mapped horizons based on the geometrical model of the developable surface. Our method involves treating real geological surfaces as approximations to developable surfaces and determines the generator lines at different points on the surface. At these points we consider strip samples of the surface radiating in different directions and examine the variability of strike and dip within each sample strip. The optimal value of the radial scan-line length can be easily identified by geostatistical analysis of the depth data. The local plunge lines are therefore identified as the direction associated with the most constant strike and dip. The map pattern obtained by analysing the plunges and trends of plunge lines across an area allows the identification of domains where folding accords closely with a developable geometry. According to the model, deviations from these patterns correspond to regions of structural complexity.
