“…In a plan view at reservoir depth, this cloud is elongated in shape in a direction close to that of the maximum horizontal stress component [9]. Seismic surveys are routinely used to delineate reservoir structure and evaluate cap-rock integrity in the field of petroleum engineering [10][11][12]. Much specific work in hard rocks can be found for a quantitative interpretation of the spatial structure of the seismic cloud, for mapping fault zones [13][14][15] and for discussing stress perturbation along sheared areas [16].…”

“…The accuracy of the travel time between the two geophones on both sides of the reservoir was in the range of 0.05 millisecond, about ten times the accuracy of time measurements in surface seismic surveys (Deflandre et al, 1995).…”

Résumé -Suivi sismique des stockages de gaz naturel -IFP Energies nouvelles, la CGGVeritas et GDF Suez ont mené ensemble, depuis 1980, de nombreuses expériences de monitoring sismique afin de détecter et de suivre les mouvements du gaz dans des stockages géologiques de gaz naturel. Des acquisitions ont été réalisées à différents stades de la vie du stockage tant en sismique de surface qu'en sismique de puits. Des antennes de récepteurs permanentes ont été construites et implantées dans des puits. Des sources permanentes ont été conçues et utilisées de façon continue pendant plusieurs années pour suivre le cycle remplissage/extraction du stockage. Les dispositifs permanents ont permis d'améliorer la précision des mesures de temps d'arrivée jusqu'au dixième de milliseconde. L'arrivée de gaz dans un aquifère se traduit par une rapide variation de vitesse, qui a un impact à la fois sur les temps d'arrivée des réflexions sous les réservoirs et sur les amplitudes aux limites du réservoir. Les mouvements ultérieurs du contact gaz/eau avec le cycle de remplissage/soutirage sont plus difficiles à suivre et nécessitent une excellente précision des mesures de temps d'arrivée des réflexions. L'inversion de ces mesures pour l'estimation des saturations en gaz et en eau est délicate. Cette inversion a été tentée, avec un certain succès, dans le cas de Céré-la-Ronde. Du fait de la densité du dioxyde de carbone, au-delà d'une profondeur de 800 mètres environ, cette inversion risque d'être encore plus délicate pour les stockages de CO 2 que pour les stockages de gaz naturel.

“…The use of permanent sensors is better adapted to long-term monitoring allowing to perform time lapse seismic acquisitions (such as Vertical Seismic Profiles) in optimal conditions, as they were initially designed for [3]. The technology has been improved overtime with the development of downhole digital telemetries that strongly reduce ambient-noise effect by comparison with analogical options.…”

This paper aims at presenting what induced microseismicity is and how it is useful to produce source rock and tight formations. We use our 30-year experience in the field to discuss on data acquisition, processing and interpretation issues. In particular, we establish the difference between hydraulic fracture mapping and long-term monitoring of reservoir mechanical behavior. We comment on advantages and drawbacks of the different monitoring scenarios -from surface acquisition to the use of downhole sensors- while discussing location issues. We illustrate the interest of working on the raw data in order to benefit from valuable information contained into the signal signature. We also refer to examples from the literature to discuss induced seismicity associated with shale play production showing solicitation of conjugate fracture networks or re-activation of faults. Using the north American experience, we introduce the recent debate on anthropogenic seismicity referring to what is currently observed in Oklahoma (US) and western Canada.
