  • Method for predicting quantitative values of a rock or fluid property in a reservoir using seismic data
    Patent number: 7373251
    Abstract: A method is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume. A first predicted value of the designated rock or fluid property is also assigned to a volume of a multi-dimensional, multi-scale model. A first predicted value of seismic response for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. A synthetic trace is generated and iteratively compared to the corresponding trace obtained from one or more sets of actual seismic data to determine a difference while consistency is maintained between the types, scales and dimensions of values and data.

  • Method for predicting quantitative values of a rock or fluid property in a reservoir using seismic data
    Patent number: 6302221
    Abstract: A method is provided for predicting a value of a designated rock or fluid property in a subterranean geologic volume. An experimentally determined seismic value of acoustic impedance is assigned to a model volume correlated to the subterranean geologic volume. A first predicted value of the designated rock or fluid property is also assigned to the model volume. A first predicted value of acoustic impedance for the model volume is calculated from a response model using the first predicted value of the designated rock or fluid property, wherein the response model is responsive to changes in predicted values of the designated rock or fluid property. The first predicted value of acoustic impedance is compared to the seismic value of acoustic impedance to determine a difference between the predicted and seismic values of acoustic impedance.
