摘要： 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.

摘要： A positioning member (11) for a tubular (10) is formed using a prefabricated fiber-reinforced resin shell (1) positioned upon a surface of the tubular and bonded to provide a protrusion upon the surface of the tubular. In a disclosed method a fiber-reinforced resin shell (1) is secured to an external surface of a tubular (10) thereby enclosing a cavity between the shell (1) and the surface of the tubular (10); a bonding agent is introduced through inlet ports (5) in a surface of the fiber-reinforced resin shell (1) to fill a cavity between the shell (1) and the surface of the tubular (10), and the bonding agent is cured.

摘要： A constant force device has at least a first non-constant axial force driving the first set of arms and a second non-constant axial force driving the second set of arms, where the two sets of arms are offset from one another by 90°. Each of the non-constant axial forces is converted to a radially extending force by the interaction of a force guide and actuator. The force guide is attached to the inner mandrel of the constant force device and is shaped to produce an essentially constant radially extending force through the entire range of motion of the arms. Typically each arm of the pair of arms has a pivoting arm and a telescoping arm where the joint between the pivoting arm and telescoping arm has one or more wheels to reduce friction as the constant force device moves through the tubular. Generally the first pair of arms is opposed to and overlaps by some distance the second pair of arms where the second pair of arms is 90° offset from the first pair of arms. Additional features may include friction reducing members at the joint between the telescoping arm and the pivoting arm, an extension lock, extension limiters, and rotating force guides.

摘要： A drill string stabilizer has an elongated cavity formed in an exterior surface of the body. An elongated blade is generally disposed to extend from the cavity. The blade is extended or retracted by rotating a stud threaded on opposite ends with left and right handed threads. Rotation of the stud causes axial movement of slide blocks threadingly engaged to the stud. A follower and track between the body and the slide blocks causes the slide blocks to slidingly engage the body. The blade track is inclined relative to the body track so that the blade radially retracts or extends relative to the body as blocks are moved along their respective tracks by rotation of the stud. The position of each stabilizer blade is independent of the other blades.

摘要： A downhole tool for use in wellbores comprises a layer of hydrophobic material over a body, wherein the layer of hydrophobic material comprises a transition metal boride having a higher hydrophobicity than the body. The downhole tool may comprise a body having a composition and the layer of hydrophobic material comprising a discontinuous phase of the transition metal binder dispersed within a first continuous phase comprising a metal binder. The layer of material may be chemically bonded to the body. An interface between the body and the layer of material may comprise the transition metal boride dispersed within a second continuous phase comprising the metal binder and the composition of the body. Methods of forming downhole tools include forming such a layer of material at a surface of a body of a downhole tool.
