    摘要: A method for use in improving marine seismic data quality includes: designing a filter for suppressing the effect of a ghost reflection in a set of stacked, marine seismic data representative of a subterranean formation, the filter compensating for amplitude due to the presence of the ghost reflection separately from the phase due to the presence of the ghost reflection; and applying the filter to the seismic data to suppress the effect of ghost reflection. The designing includes: iteratively defining at least one parameter of the filter and applying the defined filter to the seismic data; evaluating each iteration of the filters application to at least a subset of the seismic data; and selecting a defined filter from one of the evaluated iterations.

    摘要: A method for detecting hydrocarbons is described. The method includes obtaining seismic data associated with a body of water in a survey region. Then, a filter is applied to at least a portion of the seismic data to enhance diffraction anomaly signals with respect to horizontal or nearly horizontal signals associated with the water-column to form filtered seismic data. Once filtered, seepage locations are identified from the filtered seismic data

    摘要: Seismic data processing using one or more non-linear stacking enabling detection of weak signals relative to noise levels. The non-linear stacking includes a double phase, a double phase-weighted, a real phasor, a squared real phasor, a phase and an N-th root stack. Microseismic signals as recorded by one or more seismic detectors and transformed by transforming the signal to enhance detection of arrivals. The transforms enable the generation of an image, or map, representative of the likelihood that there was a source of seismic energy occurring at a given point in time at a particular point in space, which may be used, for example, in monitoring operations such as hydraulic fracturing, fluid production, water flooding, steam flooding, gas flooding, and formation compaction,.

    摘要: - Méthode d'exploitation d'un gisement pétrolier selon un schéma d'exploitation donné, à partir d'une carte de faciès représentative du gisement.
    - On réalise de nouvelles mesures au sein du gisement permettant de mieux le caractériser. On choisit un simulateur géostatistique. Puis, on identifie un jeu de nombres aléatoires qui, donné à ce simulateur géostatistique, fournit une représentation en faciès identique à la carte initiale, en inversant l'algorithme de génération de nombre aléatoire de ce simulateur géostatistique. On modifie alors la carte pour prendre en compte les nouvelles mesures, en réalisant une simulation géostatistique contrainte par ces mesures, au moyen du simulateur géostatistique et du jeu de nombres aléatoires. Enfin, on modifie le schéma d'exploitation du gisement en tenant compte de la carte ainsi modifiée, et on exploite le gisement en mettant en oeuvre le schéma d'exploitation modifié.
    - Application notamment à l'exploitation de gisements pétroliers.
