A fluid for controlling the permeability of a subterranean formation having an aqueous solution of at least one thermo-responsive polymer with block structure A-B-A', wherein At least one of the repeat units has a solubility of the corresponding monomer, in water at 20° C., equal to or greater than 120 g/l, and n is a whole number within the range 30-1000. The fluid is also used in a method for controlling the permeability of a subterranean formation.

A turbine current generator includes a hollow bearing cylinder to be engaged inside a pipe or a duct for the transit of a fluid, in particular a fluid transit duct deriving from the drilling or exploration of an oil field; a hollow rotating cylinder rotatably and coaxially engaged inside the bearing cylinder and defining a respective transit cylindrical chamber for a fluid. The bearing and rotating cylinders defining at least a cylindrical gap; one or more magnetic or electromagnetic components operatively engaged to the bearing cylinder and/or to the rotating cylinder to generate at least one electric current during the rotation of the rotating cylinder inside the bearing cylinder; an impeller or impellers arranged in the chamber of the rotating cylinder according to positions aligned along a longitudinal axis of the latter, the impellers engaged inside the rotating cylinder to rotate integrally with the latter upon the action of a fluid.

A process and system for applying a liner to an inner surface of a pipeline uses an 'inversion' technique to apply the liner. This involves arranging the liner into everted and non-everted portions and driving the non-everted portion through the pipeline such that it everts and is applied to the inner surface of the pipeline. At least first and second pipeline vehicles are used to drive the non-everted portion of the liner through the pipeline.

Composite tubular element and relevant manufacturing method

An electro-acoustic transducer includes a tubular body extending a longitudinal direction and having two end portions, opposing each other longitudinally, and internally having a first chamber, sending with the first end portion and a second chamber, on one side adjacent to and in fluidic communication with the first chamber and on the other side ending with the second end portion. The first end portion is closed towards the outside by a membrane applied to the tubular body. The second end portion has openings that put it in fluidic communication to the outside of the tubular body. The first chamber containing electrical windings arranged in succession to each other in the longitudinal direction. The second chamber is filled with a liquid. A movable element is housed in the first chamber and has a permanent magnets packaged and arranged one above the other, with the magnetization alternating and separated.
