Title (EN) DETECTION OF TOOL IN PIPE
(FR) DÉTECTION D'UN OUTIL DANS UN TUYAU
Abstract: front page image
(EN)Methods and systems for determining whether a tool has been deployed below a drill pipe are provided. A downhole tool can measure various characteristics, which then can be analyzed to determine the likelihood of a tool having been deployed below the drill pipe. For example, density and porosity measurements can be affected by the presence of casing or drill pipe, and thus such measurements can provide an indication of whether the tool has been deployed below the drill pipe.
(FR)La présente invention se rapporte à des procédés et à des systèmes permettant de déterminer si un outil a été déployé en dessous d'un tuyau de forage. Un outil de fond peut mesurer diverses caractéristiques qui peuvent ensuite être analysées pour déterminer la probabilité qu'un outil a été déployé en dessous du tuyau de forage. Par exemple, Les mesures de densité et de porosité peuvent être affectées par la présence d'un boîtier ou d'un tuyau de forage et, donc, de telles mesures peuvent donner une indication du déploiement, ou non, de l'outil en dessous du tuyau de forage.
