    Abstract: Méthode d'évaluation quantitative de la tortuosité fluide dans réservoir hétérogène à partir de mesures diagraphique (Gamma Ray, densité globale et les lenteurs des ondes longitudinales et transversales) qui permet l'estimation de la perméabilité et de la taille des pores. Elle apporte une amélioration dans estimation du facteur de résistivité de formation. On procède à l'évaluation de la porosité (phi) à partir de la lenteur des ondes longitudinales, du volume d'argile (Vsh) à partir du Gamma ray et de la porosité effective à partir de phi et Vsh calculés précédemment. On détermine la tortuosité (tau) fluide en utilisant plusieurs paramètres petrophysiques. A la fin, on détermine le module d'incompressibilité de structure (Ks), le facteur de résistivité de formation (F), la saturation en eau de formation (Sw), la fréquence adimensionnelle (X), la perméabilité (KO) et la taille des pores (d).

    Abstract: A method for seismic exploration using nonlinear conversions (e.g., item 6, Fig. 10) between electromagnetic and seismic energy. Seismic returns from a source waveform (e.g., item 180, Fig. 7A) are correlated with a reference waveform (item 150, Fig. 5B), with both waveforms designed to minimize both correlation side lobes and interference from linear electroseismic effects. A waveform element (e.g., item 10, Fig 1A) is selected to be sequenced by a binary or similar digital code designed to generate an input sweep with the needed depth penetration and noise suppression. Correlation of the seismic response with the reference waveform in a data processing step mathematically aggregates the seismic response from the input sweep into a single wavelet (e.g., item 160, Fig. 6A). Preferred binary digital codes include prescribed Britains of maximal length shift-register sequences (e.g., item 100, Fig. 3A). Also, an apparatus (items 152-157, Fig. 15) for generating the desired waveforms.

    Abstract: Systems and methods are provided for a magneto- seismic exploration of a subsurface region. An electromagnetic source may transmit time-varying electromagnetic field into the subsurface region, in the presence of a static or time-varying magnetic field, such that a component of the electric field associated with the time-varying electromagnetic field is substantially parallel to an interface between two subsurface formations in the subsurface region, wherein the electric field interacts with the static or time-varying magnetic field and creates a Lorentz force in each of the subsurface formations. One or more seismic receivers may detect a seismic signal generated by a Lorentz force change at the interface between the two subsurface formations. A computer system may be programmed to process and present the detected seismic signal.
