Title

Abstract
(EN)
Methods, systems, devices, and products for hydrocarbon tubular evaluation. Methods comprise conveying the logging tool in the tubular with a carrier; inducing with a transmitter a horizontal shear (SH) wave; identifying higher order SH mode signals received at a plurality of offset receivers responsive to a higher order SH mode engendered by the horizontal shear (SH) wave; estimating a dominant frequency for higher order SH mode from the higher order SH mode signals; estimating a group velocity for the higher order SH mode from the higher order SH mode signals; and estimating a tubular parameter using the dominant frequency and the group velocity. The tubular parameter may be at least tubular thickness. The method includes estimating the tubular parameter independent of the fundamental horizontal shear wave mode (SHO).

La présente invention concerne des procédés, des systèmes, des dispositifs et des produits pour l'évaluation de tuyaux d'hydrocarbures. Les procédés comprennent les étapes consistant à transporter un outil de diagraphie dans un tuyau avec un support; induire avec un émetteur une onde de cisaillement horizontal (SH); identifier des signaux de mode de SH d'ordre supérieur reçus au niveau d'une pluralité de récepteurs de décalage en réponse à un mode de SH d'ordre supérieur engendré par l'onde de cisaillement horizontal (SH); estimer une fréquence dominante pour un mode de SH d'ordre supérieur à partir des signaux de mode de SH d'ordre supérieur; estimer une vitesse de groupe pour le mode de SH d'ordre supérieur à partir des signaux de mode de SH d'ordre supérieur; et estimer un paramètre de tuyau à l'aide de la fréquence dominante et de la vitesse de groupe. Le paramètre de tuyau peut être au moins une épaisseur de tuyau. Le procédé consiste à estimer le paramètre de tuyau indépendamment du mode d'onde de cisaillement horizontal fondamental (SHO).
