Abstract: A method for controlling a state of a first tube, said first tube being intended to be integrated in an extraction structure, a first server managing a digital descriptor of the first tube, said digital descriptor having a first set of data stored on at least a first memory, said first set of data comprising at least: one identification number of the first tube and; a completion status and a planification status, the method includes generating a first request to a first server from a computer located near the first tube acquiring the identification number in order to generate an inventory status of the first tube, acquiring a first value of a completion status of the first tube, acquiring a second value of a planification status of the first tube, and generating at least one alert when the first or the second value is equal to a predefined state value.

Abstract: A threaded connection including first and second tubular components, each including a respective male and female end, the male end includes at least one threaded zone on its external peripheral surface and ending in a terminal surface, the female end includes at least one threaded zone on its internal peripheral surface and ending in a terminal surface, the threaded zones including, over at least a portion of their length, threads each including, viewed in longitudinal section passing through the axis of the tubular component, a thread crest, a thread root, a load flank, and a stabbing flank. Profiles of the male and female load flanks, viewed in longitudinal section passing through the axis of revolution of the connection, are a continuous curve with a convex or concave form, the profile of the male flanks being complementary to that of the female flanks over at least 70% of the continuous curve.

Abstract: A component used for drilling and operating hydrocarbon wells which is substantially tubular in form, and including a first end configured to be connected to a second end of another component also used for drilling and operating hydrocarbon wells. The first end includes a terminal portion including a first abutment surface configured to cooperate by interference with a corresponding abutment surface on the second end, and including a sealing surface configured to cooperate by interference with a corresponding sealing surface on the second end, the terminal portion being preceded by a threaded zone configured to be made up into a corresponding threaded zone of the second end. A compressible volume is provided in the thickness of the first terminal portion and partially beneath the sealing surface, to reduce radial stiffness of the terminal portion by at least 20%, while conserving at least 60% of axial stiffness.
