A method having application for the development of oil reservoirs for automatically extracting from a seismic image pertinent information for sedimentologic interpretation in order to reconstruct the depositional conditions under which sedimentary
layers have formed, by means of estimations of realistic chronological scenarios of sedimentary
layers deposition. The method comprises iterative
estimation of a first and of a second chronological
scenario of the deposition of sedimentary
layers, assuming that each reflector settles at the earliest, respectively at the latest possible moment during the sedimentary depositional process. A chronological
level number is assigned to a group of initial reflectors. Then a chronological
level number incremented by one, respectively decremented by one, is assigned to the reflectors made up from pixels located above, respectively below the initial reflectors and above, respectively below no other reflector. An interpretation of these two chronological scenarios is eventually carried out so as to reconstruct the depositional conditions of the sedimentary layers.
