    Abstract: A tubular string for a subterranean well comprises a first string that is located in the well and that can access or traverse horizons of interest, such as during drilling, completion, or workover. A second tubular string is assembled above this first tubular string and is selected so that only this second tubular string normally traverses a blow out preventer during periods when there is an elevated risk that the blow out preventer will be actuated. The second tubular string is made of a more easily shearable material than the first tubular string, such as a titanium alloy, an aluminum alloy, or a composite material. A third or further tubular strings may be assembled above the second tubular string, such as in subsea applications.

  • Patent number: 8863784
    Abstract: A system, in certain embodiments, includes a multi-layer composite strip of pipe dampening materials, comprising a first layer of a first material, a second layer of a second material disposed adjacent to the first layer of material, and a third layer of a third material disposed adjacent to the second layer of material, wherein the second material comprises a viscoelastic material, and wherein the multi-layer composite strip of pipe dampening materials is configured to be affixed to an outer surface of a section of pipe. In certain embodiments, the first layer and the third layer may have stiffness values that are substantially different from each other. The difference in stiffness values may enable relative motion in the first layer and the third layer to be generated during vibration of the section of pipe, and the energy may be dissipated by the viscoelastic material, thereby dampening vibration of the section of pipe. In certain embodiments, multiple strips of pipe dampening materials may be used.

  • Publication number: 20140291032
    Abstract: A process for the production of a pipe comprising: an interior surface having a shape; and a thermoplastic inliner is provided. The process comprises: introducing the thermoplastic inliner into the interior of the pipe; heating the pipe from the outside to a temperature higher than a crystallite melting point (Tm) of a moulding composition of an exterior surface of the inliner; expanding the inliner radially in the pipe so that an exterior surface of the inliner assumes the shape of the interior surface of the pipe; and cooling the inliner; wherein a cross section of the inliner is optionally reduced through exposure to an exterior force prior to being introduced into the pipe. Relative movements between carrier pipe and inliner are thus prevented; the risk of collapse of the inliner is moreover low. The pipe is used for the production of a laid pipeline.
