68	Intermittently rotating drilling tool	EP84300227.0	1984-01-13	EP0149290A2	1985-07-24	WALTER, Bruno H.
In an intermittently rotating down-hole drilling tool a closed valve (17) is operatively moved downwards by pressurised drilling mud pumped down the drill string (11), the valve when it attains its lower position being opened and being returned under the influence of a spring (40) or other upward urging means acting on the valve to its upper position at which the valve is closed, thereby completing the cycle of operations. The valve is continuously coupled to a torque member (71) such that the downward movement of the valve causes the torque member to turn in one direction, and the upward movement of the valve causes the torque member to turn in the opposite direction. A drill bit (103) mounted on the lower end of a rotor (75) is connected, by means of a one-way clutch (76). to the torque member so that during the downward movement of the valve the rotor and drill bit are rotatably driven by the torque member but are stationary during the upward movement of the valve the drill bit thus being operatively intermittently rotated. During the upward movement of the valve the pressurised drilling mud flows through the open valve and issues from the drill bit as high pressure and volume flushing jets while the drill bit is stationary, thereby providing a more effective cleaning of cuttings and chips from the bottom of the bore hole being formed by the drill bit. Aligned annular grooves (87, 88) are provided in the rotor and in the housing in which the rotor is mounted, ball bearings (89) being partially disposed in each of these grooves, thereby to provide an axial thrust bearing (86) capable of transmitting high axial thrust from the housing to the rotor and hence to the drill bit. Lipped pockets (90) are also provided in the rotor in communication with the grooves therein, with the ball bearings being disposed within these pockets during assembly and disassembly of the rotor and housing.

71	DIRECTIONAL DRILLING WHILE CONVEYING A LINING MEMBER, WITH LATCHING PARKING CAPABILITIES FOR MULTIPLE TRIPS	EP15857712	2015-10-26	EP3186466A4	2018-03-14	JEREZ HERNANDO; HAY RICHARD T; EVANS JOHN G
A method and system for directional drilling while conveying a liner, with latching parking capabilities for multiple trips, is disclosed. As the wellbore is drilled, each casing and liner is installed having upper and lower interior latch couplings. A liner to be installed below a parent casing includes an exterior latch assembly dimensioned for connection to the interior latch couplings of the parent casing. A bottom hole assembly may include upper and lower exterior inner string latch assemblies for connection to the upper and lower interior latch couplings of the liner to be installed. Such arrangement allows the liner to be conveyed and installed with the bottom hole assembly while directional drilling and for the liner to be temporarily hung from the parent casing for bottom hole assembly change-out while drilling. Float plugs dimensioned to be landed at lower liner interior latch couplings may be provided for cementing operations.
72	INITIATOR NANOCONSTITUENTS FOR ELASTOMER CROSSLINKING AND RELATED METHODS AND ARTICLES	EP15857345.1	2015-11-02	EP3215708A1	2017-09-13	KHABASHESKU, Valery, N.; GOODSON, James, Edward
An initiator nanoconstituent comprises a nanoparticle covalently bonded to a group having a free radical. The nanoparticle may be bonded to the group via an ether group or an amide group. The initiator nanoconstituent may be formed in situ, in a mixture comprising an elastomer material to be crosslinked. The initiator nanoconstituent is formed from an organic nanoconstituent compound that includes the nanoparticle and an organic group that does not include a free radical at the time the mixture is formed. At least one chemical bond of the organic nanoconstituent compound may be ruptured, in situ, to form the initiator nanoconstituent, which may then bond with polymer molecules of the elastomer material and form a crosslinked elastomer material. Downhole tools or components thereof may include such crosslinked elastomer material.
73	Rotatable wireline tool of enhanced hydraulic drive consistency	EP11250926.0	2011-12-13	EP2466056A3	2016-01-06	Jensen, Michael
A rotatable downhole cutting tool configured for enhanced drive consistency in low power circumstances. The tool is equipped with a hydraulic axial drive actuator suitable for use in wireline deployment. The actuator itself includes a reciprocating piston with a ball screw that threadably interfaces a ball nut for dampening the axial drive imparted by the piston. As such, even though hydraulically driven at generally well under about 10 horsepower, bounce in the axial drive is substantially eliminated. This is particularly advantageous where cutting is to be applied to downhole metal based obstructions.
