Title (EN) ACTIVE RANGING-WHILE-DRILLING WITH MAGNETIC GRADIOMETRY
(FR) TÉLÉMÉTRIE ACTIVE PENDANT LE FORAGE AVEC UNE GRADIOMÉTRIE MAGNÉTIQUE
Abstract:
(EN) Systems and methods for active ranging-while-drilling (ARWD) for collision avoidance and/or well interception. A method for ranging while drilling may comprise employing a rotating magnet assembly to induce a changing magnetization and/or electric current in a conductive member disposed in a target wellbore, wherein the rotating magnet assembly may be employed in a second wellbore; measuring at least one component of a magnetic gradient tensor using receivers; and calculating a relative location of the conductive member based at least in part on the measurements of the at least one component of the magnetic gradient tensor.
(FR) La présente invention concerne des systèmes et des procédés permettant une télémétrie active pendant le forage (ARWD pour Active Ranging While Drilling) pour un évitement de collisions et/ou une interception de puits. Un procédé permettant une télémétrie pendant le forage peut consister à utiliser un ensemble aimant rotatif pour induire une magnétisation changeante et/ou un courant électrique dans un élément conducteur disposé dans un puits de forage cible, l'ensemble aimant rotatif pouvant être utilisé dans un second puits de forage ; à mesurer au moins une composante d'un tenseur de gradient magnétique à l'aide de récepteurs ; et à calculer une position relative de l'élément conducteur en se basant, au moins en partie, sur les mesures de la ou des composantes du tenseur de gradient magnétique.
