Interactive salt and sediment evolution: self-consistent quantitative models

摘要: Abstract Assessment of the combined evolution salt and surrounding sediments is one major problems in salt-dominated basins. A quantitative approach, guided by observations from seismic and/or well data, presented. The modeled present-day shape a structure constrained an inverse non-linear procedure which determines parameters controlling shape. guarantees to be close correspondence with observed By introducing time dependence each shape, permits assessment evolving time. letting sedimentary beds move around developing structure, influence uprising on bed geometries above depicted. As predicted must also accord rim syncline geometries, additional constraints are put dynamic structure. automatically determines, self-consistent way, resolution sensitivity all model, both formations. handles symmetric asymmetric two-dimensional structures as three-dimensional structures. Applications given two North Louisiana basin. first tall diapir clearly defined synclines. varying procedure, consistent reproduction data obtained sides diapir. In addition, regions where absence greatest, model provides measure degree, extent location allowed overhang order that shapes accord. Therefore, produces quantified stock stem width locations both. second consists pillows. Here picture shaping mound relation their common syncline. synthetic case exemplifies capability modeling salt-sediment constraint depositional surfaces through horizontal. dynamical then better understanding stress-strain, thermal focusing hydrocarbon entrapment realized.
