20090050327 | Switching Apparatus Between Independent Control Systems for a Subsurface Safety Valve - A system is provided for switching between redundant control systems for a subsurface safety valve (SSV) while being able to isolate the closure spring from hydrostatic pressure in the control line of the system that is not being used. There are two control lines that connect to discrete operating pistons that are both coupled to the flow tube. Each operating piston is connected to a control rod with the control rods terminating near opposed ends of a pivoting member. Pushing down on one rod pushes up on the other rod so that the other rod is held supported and the hydrostatic pressure in its associated control line doesn't affect the force needed by the closure spring to close the SSV. Releasing control line pressure puts the system in neutral to allow either of the systems to be reselected. | 02-26-2009 |

The Control Module receives pressurized fluid medium, internally shifts the fluid medium flow into and out of Canister Modules, and exhausts depressurized fluid medium. The Canister Modules perform the work for each actuator application, and are attached to the Control Module by Canister Adjustment Plates at each end of the Control Module, which allows attachment to different diameter canister modules simultaneously. The Canister Modules may operate at different pressures, different volumes, or perform different applications simultaneously. A modified embodiment includes a Control Module compatible with external switching systems while maintaining central fluid control and modular efficiency. | 09-09-2010 |

20090242384 | Low Pressure Mixing System for Desalting Hydrocarbons - A method and system for reducing the salt content of a crude oil stream includes using a quill to disperse a water stream into the crude oil and then routing the mixed oil/water stream through a plurality of mixing stages. The water stream may include a wash water that has been preconditioned with recycled effluent water. Each mixing stage increases the homogeneity of the mixed oil/water stream. The first and third mixing stages are preferably lower pressure stages relative to the second mixing stage, which provides pressure effective for flowing the mixed oil/water stream through the third and fourth mixing stages. Upon exiting the fourth mixing stage, the mixed oil/water stream is electrostatically treated in a dual frequency separator vessel or a dual polarity separator vessel. | 10-01-2009 |
20140165833 | A Method For Extending Turndown In A Gas-Liquid Separator - A system and process for extending turndown in a gas-liquid separator is presented.
