| 321 | DOWNHOLE MAGNETIC PARTICLE DELIVERY SYSTEM FOR OIL AND GAS WELLS | US12790151 | 2010-05-28 | US20110290506A1 | 2011-12-01 | Murat Ocalan; Manuel Marya |
| The subject disclosure discloses an apparatus and method of conveying magnetic particles into a wellbore. A plurality of particles which are magnetically attracted to one another in response to exposure to a magnetic field are delivered downhole via a degradable material. The degradable material confines the particles and conveys the particles to a desired location downhole. The structure comprising the degradable material and the confined particles can be lowered into a subterranean well by a cable or wire, or alternatively released into the well under the influence of gravity and flow induced forces. The material degrades in response to conditions encountered in a subterranean environment thus releasing the particles. | ||||||

| 324 | COMPLETION SYSTEM FOR SUBSURFACE EQUIPMENT | US12510978 | 2009-07-28 | US20110024102A1 | 2011-02-03 | Gary Allen Ring |
| A concentric tubing well completion method and a subsurface annular flow crossover system are provided. The well completion method creates at least three separate, pressure isolated annular flow channels in a wellbore. The subsurface crossover provides for switching fluid flow between the annular flow channels within the completed well. The crossover system can be used in conjunction with other subsurface equipment to more efficiently manage fluid flows in the completed well. For example, fluid from any subsurface reservoir or separate reservoirs can be delivered to the surface. In addition, flow paths can be provided for a fluid circulation loop from the surface, a subsurface fluid lifted to the surface or a fluid moved to a different depth in the well for reinjection. The subsurface crossover also provides a method to shift the fluids from one annular fluid channel to another. The subsurface annular flow crossover system also allows the installation of a device at any intermediate depth in the well while allowing fluid flow past the device thus eliminating the disruption or blocking of the flow for the purposes of heat and produced fluid extraction. For example, the crossover can be used to maintain separation between a working fluid and produced fluids in a subsurface heat exchanger used in a geothermal well or a subsurface turbomachinery such as a subsurface pump. | ||||||

| 328 | PRESSURE COMPENSATION/CONTROL FOR FAIL-SAFE GATE VALVE | US10036997 | 2001-12-21 | US20030116733A1 | 2003-06-26 | Loc G Hoang; Jim E. Kilmoyer |
| A fail-safe gate valve for sub-sea use features a floating, pressure biased compensating piston whose movement prevents internal pressure buildup from opening movement of the gate. A pre-charged fluid chamber provides the bias on the balancing piston. Using unequal piston diameters reduces the charge pressure. The balancing piston is not connected to the gate so that internal pressures can be employed to act on a net area, which biases the gate toward its fail-safe position. | ||||||
