A method associated with the selection of tubulars for hydrocarbon production is described. In particular, the method is associated with the evaluation of performance limits of threaded connections. In this method, constituents of an evaluation group of threaded connections are determined via model analysis. Then, physical testing on a first group of threaded connections in the evaluation group is conducted. Modeling analysis on the first group and a second group of threaded connections is performed, wherein the second group are not physically tested. Once modeled, the results from the physical testing and the modeling analysis are compared to assess a characteristic performance factor for the first group. Then, the characteristic performance factor is applied to the second group, and the performance limits are defined based on this characteristic performance factor.

La présente invention concerne un procédé lié au choix de tubulures pour la production d'hydrocarbure. En particulier, le procédé est lié à l'évaluation des limites de performance de raccords filetés. Dans ce procédé, on détermine les constituants d'un groupe d'évaluation de raccords filetés par l'intermédiaire d~une étude sur modèle. Puis, on effectue un essai physique sur un premier groupe de raccords filetés dans le groupe d~évaluation. On effectue une étude de modelage sur le premier groupe et un second groupe de raccords filetés, le second groupe ne subissant pas d~essai physique. Une fois le modelage effectué, les résultats de l'essai physique et de l'étude de modelage sont comparés de façon à évaluer un facteur de performance caractéristique pour le premier groupe. Puis, le facteur de performance caractéristique est appliqué au second groupe, et les limites de performance sont définies sur la base de ce facteur de performance caractéristique.
