The robust, high fatigue performance and fast make up of TenarisHydril BlueDock premium connector yielded optimal running times for customers Repsol and YPFB Andina drilling complex wells in Bolivia. The analysis, engineering and field service work carried out by Tenaris for Repsol and YPFB Andina generated a successful running of 30” diameter BlueDock weld-on connectors in Bolivia. In the six gas wells, with a depth near 5.500 meters, the incorporation of the premium connector, which has optimized design characteristics, helped to reduce operating times, increasing the installation speed by 120% compared to technologies previously used.The complex geology of the subsoil and the significant depth of the most productive target formations in Bolivian gas fields require multiple casing sections. For this reason, operators must carry out important investments for the drilling, development, completion and start up of these wells.BlueDock premium connector incorporates design concepts from the extensively tested Blue Series, and provides reliable performance in the most complex ultra-deepwater operations requiring gas sealability and fatigue performance. This Tenaris's integrated solution grounds on experience in pipe manufacturing, premium connection design and welding technology. Pipe and connector are manufactured under the same quality management system, allowing us to supply a full casing and tubing package for offshore wells. Success with major operators is backed by Tenaris's global service network providing technical assistance, product testing, pipe management and technical support in the field.
