| 121 | Casing valve | US14711993 | 2015-05-14 | US09359859B2 | 2016-06-07 | Shaun Compton Ross; Leslie David Jarvis |
| A safety mechanism (401) comprising: (i) an obstructing member (412,414) moveable between a first position where fluid flow is permitted, and a second position where fluid flow is restricted; (ii) a movement mechanism (416,418); (iii) a wireless receiver (360), optionally a transceiver, adapted to receive a wireless signal such as electromagnetic or acoustic. The movement mechanism (416,418) is operable to move the obstructing member (412,414) from one of the first and second positions to the other of the first and second positions in response to a change in the signal being received by the wireless receiver (360). The safety mechanism also has (iv) a valve (401) in a casing sub; the valve (401) being adapted to move from one of the first and second positions to the other of the first and second positions, and then back to the first of the first and second positions. | ||||||
| 122 | LCM recovery tank | US14534929 | 2014-11-06 | US09222319B1 | 2015-12-29 | Nathan Berg; Josh Bradford |
| An LCM recovery system that relies on gravity and density or specific gravity differences between three of the main components of drilling fluids, i.e., the mud and chemicals, lost circulation material (LCM) or additives, and drill solids or cuttings. Fluid enters the LCM recovery tank from the well via a flow line or mud gas separator return leg. Cuttings, having a greater density than additives, tend to settle and become trapped on the input side of the LCM recovery tank. The less dense fluid and entrained or suspended LCM tends to travel over the baffle near the center of the tank. LCM can then be efficiently returned to the active mud system for reconditioning or pumping downhole again. | ||||||
| 123 | MAGNETIC HOLDING BRAKE AND ACTUATOR WITH A MAGNETIC HOLDING BRAKE | US14427301 | 2012-09-10 | US20150300520A1 | 2015-10-22 | Norbert LENZ |
| A magnetic holding brake (1) having at least one turning brake member (4) allocatable to a rotatable part (2) of an actuator (3) and a fixed brake member (6) allocatable to a torque-proof part (5) of the actuator (3). The turning brake member (4) and the fixed brake member (6) each at least have one permanent magnet (7, 8) of different polarity. The permanent magnets are lying opposite to each other in a pre-defined relative position of the turning brake member (4) and the fixed brake member (6) under exertion of a braking or holding torque. In this manner, the possibility exists that a holding in the so-called “fail as is”-mode is more easily and reliably and at the same time cost-efficiently achievable without wear or further energy demand. | ||||||

A motor is coupled to the transmission so that operation of the motor causes rotation of the sleeve. | ||||||

| A well is drilled and casing installed utilizing a casing drilling technique. A bottom hole assembly having a drill bit and a fluid diverter is secured to a string of drill pipe and installed within a casing string. Drilling fluid is pumped down the drill pipe string to cause the drill bit to rotate and drill the well while the fluid diverter is in a drilling mode position. At the total depth for the casing string, the operator moves the fluid diverter to a cementing position and pumps cement down the drill pipe and up the casing string annulus. After cementing, the operator moves the fluid diverter to a packer set position and again pumps drilling fluid down the drill string to set the packer. | ||||||

| 139 | Safety Mechanism For A Well, A Well Comprising The Safety Mechanism, And Related Methods | US13811151 | 2011-07-20 | US20130175094A1 | 2013-07-11 | Shaun Compton Ross; Leslie David Jarvis |
| A safety mechanism comprising: an obstructing member moveable between a first position where fluid flow is permitted, and a second position where fluid flow is restricted preferably blocked; a movement mechanism; and a wireless receiver, often an acoustic transceiver, adapted to receive a wireless signal; wherein the movement mechanism is operable to move the obstructing member from one of the first and second positions to the other of the first and second positions in response to a change in the signal being received by the wireless receiver. Embodiments of the invention thus provide a safety mechanism for a well such as a valve, packer, plug or sleeve, which can be operated wirelessly and so may allow operation of safety mechanisms in a well even when emergency situations have occurred. | ||||||
| 140 | Completion system for subsurface equipment | US12510978 | 2009-07-28 | US08439105B2 | 2013-05-14 | Gary Allen Ring |
| An apparatus for creating multiple and isolated well flow paths operating at different pressures in the wellbore is described. These multiple flow paths establish a full circulation loop with the surface and a remaining isolated flow channel produces reservoir fluids to the surface. Heat is transferred from the produced reservoir fluid into the circulated loop via a unique down-hole heat exchanger. The flow of reservoir fluid through the isolated annular well channel allows for more efficient and extensive extraction of heat from the reservoir fluid compared with merely heating the circulating loop via the well bore exterior surface. | ||||||
