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.

Abstract: 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.

Abstract: A safety guard apparatus for use on a pitched roof includes two or more units having a first member attached to a roof member and second and third members serving as an upright guard rail support. A distal end of the first member has fixed thereto a tubular collar having an axis at a right angle to the first member, and a fourth rigid elongate member is adjustably slidably fitted through the collar so that a lower end thereof may abut a vertical wall below the roof to support the apparatus above the roof.
