摘要：A method and apparatus for the exploration of hydrocarbons comprising thesteps of: obtaining a set of seismic signal traces distributed over a predetermined three-dimensional volume of the earth; dividing the three- dimensional volume into a pluralityof analysis cells having portions of at least two seismic traces located therein; computingouter products of the seismic traces within each cell; forming the covariance matrix foreach cell from these outer products; computing the dominant eigenvalue and the sum ofthe eigenvalues of the covariance matrix of each cell and computing a seismic attributefrom the ratio of the dominant eigenvalue to the sum of the eigenvalues of thecovariance matrix of each cell; and forming map of the seismic attributes of selectedgroups of cells.
