Abstract
A method associated with the selection of tubulars for hydrocarbon production is described based upon evaluating the performance limits of threaded connections. Constituents of an evaluation group of threaded connections are determined and then a first group of the connections is evaluated via model analysis over a range of conditions. Then, physical testing on a first group of threaded connections in the evaluation group is conducted over that range of conditions. Once modeled, the results from the physical testing and the modeling analysis of the first group are compared to assess a characteristic performance factor for the first group. A second group of threaded connections are determined and the assessed performance factor from the first group is applied to a second group, and the performance limits of the second group are defined over the range of conditions based on this characteristic performance factor, without requiring testing the second group.
