摘要： An method of constructing a geological model of a subsoil formation constrained by seismic data having application to petroleum reservoir development is disclosed. Logs relative to geological properties are acquired and a seismic facies cube is constructed. Logs relative to geological properties and logs relative to seismic facies are then simulated. Then distribution of proportions is estimated at any point on the subsoil by means of the acquired logs in the well and of the simulated logs. A seismic constraint is then defined by constructing a lithologic facies average proportion cube from these estimated proportion distributions. Finally, a geological model wherein the geological properties are constrained by this lithologic facies average proportion cube is constructed.

摘要： A method for facilitating monitoring, in the course of time, of the evolution of the physical states of a zone of an underground formation such as a reservoir by using and interpreting 4D seismic data. The method uses seismic pattern recognition, more particularly a fuzzy discriminant analysis technique allowing to integrate the uncertainties on the seismic measurements in the interpretation. The uncertainties taken into account are evaluated on parts of seismic traces obtained during successive seismic surveys, corresponding to zones of the underground formation (outside the reservoir) where the physical states monitored have undergone no significant change. The invention is useful for monitoring of the evolution of a hydrocarbon reservoir during production.
摘要翻译：通过使用和解释4D地震数据，便于在时间上监测诸如储层的地下地层的区域的物理状态的演变的方法。该方法使用地震模式识别，更具体地说，一种模糊判别分析技术，可以将解释中的地震测量的不确定性整合起来。考虑到的不确定性是对连续地震勘测期间获得的地震迹线部分进行评估的，对应于受监测的物理状态没有发生重大变化的地下地层（储层外）。本发明可用于监测生产过程中碳氢化合物储层的演化。

摘要： The invention is a method for facilitating recognition of objects, using a discriminant analysis technique to classify the objects into predetermined categories. A learning base comprising objects that have already been recognized and classified into predetermined categories is formed with each category being defined by variables of known statistical characteristics. A classification function using a discriminant analysis technique, which allows distribution among the categories the various objects to be classified from measurements available on a number of parameters, is constructed by reference to the learning base. This function is formed by determining the probabilities of the objects belonging to the various categories by taking account of uncertainties about the parameters as intervals of variable width. Each object is then assigned, if possible, to one or more predetermined categories according to the relative value of the probability intervals.
