Abstract: A method for the identification of operational problems in wells that produce by gas-lift, including allowing the hydrodynamic evaluation of the well/lines set by injection of at least one alcohol in the gas-lift line, collecting samples at the well sampling point, and detecting alcohol passage and return by direct analysis of information about process variables provided by the well instrumentation.

Abstract: The present invention relates to an axial flux electric machine (1) with a stator wound with a plurality of wound cores (8) arranged on a support disk (10), in which the support disk (10) and the plurality of wound cores (8) are encapsulated in a resin (9), in which at least one continuous coiled cooling channel (12) is formed in the resin (9), during or after the encapsulation process, on each side of the support disk (10). Each continuous coiled cooling channel (12) passes close to at least one of the surfaces of each portion of the wound core (9) without touching said at least one surface.

Abstract: A method and system for indexing design elements. The method, when performed by a special purpose computer executing a design repository application, comprises creating one or more metadata entries, linking the metadata entries to one or more design elements, and providing an interface to access the design elements. The metadata entries comprise data describing the design elements located within a design repository. The interface displays the design elements in accordance with their associated metadata.
