摘要： A system and method for predicting the front arrival time in seismic monitoring is disclosed The method includes measuring or computing a physical property reference signature at a calibration point, the physical property reference signature based on a change in a physical property over time due to a well injection; computing a seismic attribute reference signature at the calibration point based on the physical property reference signature; identifying a reference marker, the reference marker corresponding to a change in the seismic attribute reference signature at the calibration point over time; detecting a measured marker, the measured marker corresponding to a change in a seismic attribute of a recorded dataset over time; calibrating the measured marker; and calculating a marker arrival time for a location other than the calibration point.

摘要： Global inversion of multi-vintage seismic data uses simulated annealing to minimize a cost function simultaneously for all vintages and all angle stacks to yield values of geophysical properties. Each vintage is generated from an independent seismic survey of a subsurface structure conducted over a distinct period of time and includes seismic traces and angle stacks. An initial model of the subsurface structure is used and includes values for geophysical properties and time shift maps between vintages. The time shift map contains shifts in the seismic trace between vintages. The cost function includes a time shift map term for the difference between the time shift map and a calculated time shift of the seismic trace between vintages and is based on a proposed perturbation to at least one of the geophysical properties. The time shift map is also used as a global constraint on proposed perturbations of subsurface properties.
摘要翻译：多老式地震数据的全局反演使用模拟退火，为使所有老式同时最小化的成本函数和所有角度叠层，得到的地球物理属性的值。每个老式从在传导在一段不同周期的地下结构的独立地震勘测中产生，并包括地震记录道和角度叠加。地下结构的初始模型被使用并且包括用于老式之间地球物理性质和时移映射值。时移映射包含在老式之间的地震道的变化。成本函数包括用于所述时间变速图和复古和基于一个建议的扰动的地球物理性质中的至少一个之间的地震道的计算的时间偏移之间的差的时间变速图的术语。因此，时移图被用作地下特性的建议扰动的全局约束。
