  • Measurement cell and associated measurement method
    Patent number: 11092588
    Abstract: A measurement cell includes: an enclosure; a flexible membrane disposed in the enclosure so as to contain a hardenable material; and means for stiffening the membrane configured to assume two alternative states: a stiffness state, in which the stiffening means resist the expansion of the hardenable material during solidification; and a flexible state, in which the stiffening means exert a stress that is less than that exerted in the stiffness state allowing at least one physical, chemical or mechanical property of the hardenable material to be measured and the hardenable material to be extracted from the enclosure; the stiffening means being produced by a set of metal wires connected to a clasp configured to modify the stiffness exerted by the metal wires.
    Type: Grant

  • Method for characterising the mechanical behaviour of cements
    Patent number: 9664648
    Abstract: The present invention relates to a method for determining mechanical parameters of a cementitious system, on the basis of time, and on the basis of the fineness of the cementitious system, pressure and/or temperature, representative of the in situ conditions found in wellbores. The initial composition of the cementitious system, the fineness ? thereof and the speed of the compression waves on the basis of time Vp(t) are the only input data of the method.
