ABSTRACT
The new oil and gas reservoirs require very demand-
ing conditions to be produced and therefore special
technologies and tubular products are needed. This
situation leads to a huge grow on the market of pro-
prietary premium connections designed to work un-
der such extreme conditions. After years of devel-
opment of “ad-hoc” testing procedures it is
necessary to perform some full scale testing proce-
dures to assure a minimum level of performance in
proprietary connections.
