Abstract
(EN)
Methods and systems are presented in this disclosure for estimation of formation properties and pipe properties using ranging measurements. Embodiments of the present disclosure utilize ranging measurements to first determine a defined slope (e.g., leakage rate) of an electrical current signal flowing along a wellbore. The determined slope (e.g., leakage rate) may be then used to estimate properties of a formation surrounding the wellbore (e.g., formation resistivity) and properties of a conductive material (casing pipe) deployed in the wellbore (e.g., pipe resistance). Based on the estimated properties of the formation and the conductive material, drilling operation in a drilling well can be adjusted, and repair of defects or mechanical deformations on the casing pipe can be initiated.

L'invention concerne des procédés et des systèmes pour l'estimation de propriétés de formation et de propriétés de tuyau à l'aide de mesures de télémétrie. Des modes de réalisation de la présente invention utilisent des mesures de télémétrie pour déterminer d'abord une pente définie (par exemple, un taux de fuite) d'un signal de courant électrique circulant le long d'un puits de forage. La pente déterminée (par exemple, taux de fuite) peut être ensuite utilisée pour estimer les propriétés d'une formation entourant le puits de forage (par exemple, la résistivité de la formation) et des propriétés d'un matériau conducteur (tuyau de tubage) déployé dans le puits de forage (par exemple, résistance de tuyau). Sur la base des propriétés estimées de la formation et du matériau conducteur, une opération de forage dans un puits de forage peut être ajustée, et une réparation de défauts ou de déformations mécaniques sur le tuyau de tubage peut être engagée.
