Title (EN) SYSTEM AND METHOD FOR GEOPHYSICAL PROSPECTING BY MEASUREMENT OF EARTH TIDES
(FR) SYSTEME ET PROCEDE DE PROSPECTION GEOPHYSIQUE PAR LA MESURE DES MAREES TERRESTRES
Abstract: front page image
(EN)To locate potentially hydrocarbon-bearing subsurface formations, tilt-meters (T1, T2, T3, T4, T5) measure the time of arrival and the apparent direction of a lunar/solar induced earth tide (24) at an array of points on the earth"s surface. The measurements are combined in a plotter (104) to determine the shape of the tidal wave in a region of interest. The shape is indicative of subsurface viscosity in the region. Subsurface formations having an abnormally low viscosity are considered potentially hydrocarbon bearing.
(FR)Pour deceler des formations sous la surface susceptibles de receler des hydrocarbures des dispositifs de mesure de l"inclinaison (T1, T2, T3, T4, T5), mesurent le temps d"arrivee et la direction apparente d"une maree terrestre induite par la lune/le soleil (24) suivant une rangee de points situes a la surface de la terre. Les mesures sont combinees dans un abaque (104) pour determiner la forme de la vague de maree dans une region d"interet. La forme indique la viscosite sous la surface de la region. Des formations sous la surface ayant une viscosite anormalement faible sont considerees comme susceptibles de receler des hydrocarbures.
