Title (EN) DETERMINING DIRECTIONAL DATA FOR DEVICE WITHIN WELLBORE USING CONTACT POINTS
(FR) DÉTERMINATION DE DONNÉES DIRECTIONNELLES POUR UN DISPOSITIF À L'INTÉRIEUR D'UN PUITS DE FORAGE À L'AIDE DE POINTS DE CONTACT
Abstract:
(EN) A system and method for providing information regarding the tortuosity of a wellbore path is provided. The method includes receiving data from a plurality of survey stations of a wellbore survey. The method further includes determining a plurality of tortuosity parameter values for the wellbore path within a corresponding plurality of analysis windows, wherein each analysis window has at least one tortuosity parameter value.
(FR) L'invention concerne un système et un procédé destinés à fournir des informations concernant la tortuosité du trajet d'un puits de forage. Le procédé consiste à recevoir des données provenant d'une pluralité de stations de sondage d'un sondage de puits de forage. Le procédé consiste en outre à déterminer une pluralité de valeurs de paramètre de tortuosité pour le trajet de puits de forage dans une pluralité correspondante de fenêtres d'analyse, chaque fenêtre d'analyse ayant au moins une valeur de paramètre de tortuosité.
