Method for constructing a geological model of a subsoil formation restricted by seismic data

摘要

The method involves generating simulated geological logs through a sequential simulation by indicatrix from the logs acquired at an oilwell. Logs of seismic facies are generated by interpreting the geological logs. A cube for distributing proportions of lithological facies is built by estimating the distributions of proportions in points of the sub soil using the acquired and simulated logs. Average proportion cube of the lithological facies is built from the distribution of the estimated proportions. A geological model is built, where properties are restricted by the proportion cube.
