Abstract: A process for constructing a well (1) for exploiting an oil or gas reservoir, comprising the following operations: (A) drilling a formation submerged by a water head, at least 3, 600 meters deep or more, reaching the formation from the surface of the water with a drilling riser (7), and a drilling tool which passes internally through the drilling riser; and evacuating through the drilling riser (7) at least one of the circulating drilling fluid, the oil or natural gas coming from the formations and the resulting drilling materials. The drilling riser (7) has an external diameter equal to or smaller than 17 inches and reaches a wellhead (3) having an internal diameter equal to or smaller than 18.75 inches, and positioned in correspondence with or close to the seabed submerged which covers the formation.

Abstract: A safety valve assembly for extradition of hydrocarbons includes a valve body including a passage duct, configured to be traversed by a production and/or drilling line. The valve body includes housings for a punch and counter-punch, arranged diametrically opposite to one another with a common longitudinal axis substantially perpendicular to the longitudinal axis of the valve. The punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe, and the counter-punch slides linearly in a controlled manner in the housing along the axis which intersects the longitudinal axis of the pipe. The punch and counter-punch are configured to allow the counter-punch to slidingly receive the punch in its interior to create two different shearing planes. The counter-punch includes a hollow part to slidingly receive the section of tubular material and the punch, in the linear movement during the shearing operation.

Abstract: A pipe for cableless bidirectional data transmission and continuous circulation of a stabilizing fluid in a well for the extraction of formation fluids includes a hollow tubular body which couples with respective drill or completion pipes; a radial valve associated with the tubular body, the radial valve connectable to a pumping system outside the tubular body; an axial valve associated with the tubular body; a communication module associated with the tubular body that includes at least one metal plate selected from a transmitting metal plate, a receiving metal plate, and a transceiver metal plate; an electronic processing and control unit that processes signals to be transmitted by means of the at least one metal plate or signals received by means of the at least one metal plate; and one or more supply batteries for feeding the metal plates and the electronic processing and control unit.
