摘要

Method for predicting quantitative values of a rock or property of fluid in a reservatu00e0rio using data su00cdsmicos. It is provided a method for predicting a volume of a property of the fluid or rock designated in a geological volume underground.A first value predicted from the property of fluid or rock also designated is assigned to a volume of a multidimensional model of multiple scales.A first value predicted from seismic response for the volume of the model is calculated from a model answer by using the first value predicted from the property of fluid or rock called, in which the model answer is responsive to changes in the values predicted from the fluid property Or rock designated.A synthetic trace is generated and iteratively compared with the corresponding trace obtained from one or more sets of seismic data effective to determine a difference while consistency is maintained between the types, scales and dimensions of data and values.The first value predicted from the property of fluid or rock designated is adjusted in response to the difference to create a second value predicted from the property of fluid or rock called, in which the second value predicted generally reduces the difference.
