Method of oil reservoir exploitation employing a facies chart construction which is representative for the reservoir

摘要

The method involves defining a visiting order for cells of a grid by determining facies discrimination degree in each cell of the grid, and defining the visiting order in an increasing order of the degree. A defined likelihood is calculated by a probability of obtaining petrophysical property values of maps in the cell according to the visiting order in the cell and for facies values such that a facies (FAC) in the cell is facies. Each cell of the grid is associated with the facies values to maximize the likelihood in the cell. An independent claim is also included for a method for developing a petroleum reservoir according to a development scheme.
