Title (EN) SYSTEM AND METHOD FOR PROVIDING A CONTINUOUS WELLBORE SURVEY
(FR) SYSTÈME ET PROCÉDÉ POUR FOURNIR UN RELEVÉ EN CONTINU DE PUITS DE FORAGE
Abstract:
(EN) Systems and methods are provided for producing a continuous survey of a previously drilled portion of a wellbore. The method includes receiving a plurality of stationary survey measurements taken at a corresponding plurality of locations along the portion of the wellbore. The method further includes receiving at least one continuous survey including a plurality of continuous survey measurements taken between a pair of stationary survey measurements of the plurality of stationary survey measurements. The method further includes combining the plurality of stationary survey measurements and the plurality of continuous survey measurements to produce the continuous survey of the portion of the wellbore.
(FR) L'invention concerne des systèmes et des procédés permettant de produire un relevé en continu d'une partie préalablement forée d'un puits de forage. Le procédé consiste à recevoir une pluralité de mesures de relevé fixes prises au niveau d'une pluralité correspondante d'emplacements le long de la partie du puits de forage. Le procédé consiste en outre à recevoir au moins un relevé en continu comprenant une pluralité de mesures de relevé en continu prises entre deux mesures de relevé fixes parmi la pluralité de mesures de relevé fixes. Le procédé consiste également à combiner la pluralité de mesures de relevé fixes et la pluralité de mesures de relevé en continu afin de produire le relevé en continu de la partie du puits de forage.
