Palaeo-Previous HitFaultNext Hit Analysis: Defining the Evolution and Impact of Faults Through Time


Quantitative Previous HitfaultNext Hit analysis is based on the principle that faults develop in three-dimensional space in a predictable way. Evaluating the results of this analysis can rapidly highlight interpretation errors and complexities related to Previous HitfaultNext Hit evolution; both of which can have important implications when considering the economic significance of a Previous HitfaultNext Hit (e.g. sealing capacity). The techniques and theories associated with Previous HitfaultNext Hit analysis are primarily derived from detailed coal-mine mapping in the mid-1980s (e.g. Watterson, 1986) but today are most frequently applied to geological models built from high-resolution 3D seismic reflection data. Despite the prevalence of detailed structural models, previous work has focused on static models with limited integration of established restoration techniques and displacement-based Previous HitfaultNext Hit analysis. While enabling definition of present-day geometries and across-Previous HitfaultNext Hit relationships, static analysis provides minimal insight into the characteristics of a Previous HitfaultNext Hit during its evolution. Here, we demonstrate how sequential backstripping and Previous HitfaultNext Hit restoration using industry standard compaction curves, allows realistic implementation of palaeo-Previous HitfaultNext Hit and seal analysis. By accounting for compaction and displacement, the true development of faults can be quantified allowing across-Previous HitfaultTop relationships and geometries to be defined at key time-steps, for instance at the time of hydrocarbon migration and trapping. The integration of these workflows is illustrated with examples of faults from areas under active hydrocarbon exploration.
