Patent application number | Description | Published |
20080210438 | Downhole Safety Valve Apparatus and Method - The application discloses a safety valve including a flapper valve and a packer assembly to be installed in a bore to isolate a first zone from a second zone. Preferably, the safety valve includes a hydraulic conduit bypassing the flapper valve to allow communication therethrough when the valve is closed. Furthermore, the safety valve preferably allows unobstructed passage of tools and fluids therethrough when the flapper valve is open. The application discloses a method to install a safety valve in an existing string of tubing by deploying a packer assembly having an integral safety valve. | 09-04-2008 |

20090205821 | Method and apparatus to treat well stimulation fluids In-Situ - A method and apparatus for the management of injection and production of well fluids in a subterranean well is described to optimize the use of stimulation fluids to enhance their compatibility with subterranean reservoirs and the surface environment and thereby reducing the damage said fluids induce in subterranean reservoirs and upon flow back to the surface reduce their damage to the environment is described. More specifically, this method is directed to the subterranean treatment of injection fluids. | 08-20-2009 |
20090308613 | METHOD AND APPARATUS TO TREAT A WELL WITH HIGH ENERGY DENSITY FLUID - The invention relates to methods and apparatuses for the subterranean injection of reactive substances like propellants into wellbores and subterranean reservoirs. These methods and apparatuses controls the temperature of a reactive substance for safe handling at surface and controls the decomposition rate of the substances in the subterranean environment. In addition, these methods and apparatuses provide a means for safe dilution of reactive fluids in the event of a leak or spillage of the reactive substance. | 12-17-2009 |
20100025032 | METHODS AND SYSTEMS TO ACTIVATE DOWNHOLE TOOLS WITH LIGHT - The present invention comprises a system and methods to actuate downhole tools by transmitting an optical signal through an optical fiber to the downhole tool. The optical signal can comprise a specific optical signal frequency, signal, wavelength or intensity. The downhole tool can comprise packers, perforating guns, flow control valves, such as sleeve valves and ball valves, samplers, sensors, pumps, screens (such as to expand), chemical cutters, plugs, detonators, or nipples. | 02-04-2010 |
20100193186 | METHOD AND APPARATUS TO CONSTRUCT AND LOG A WELL - The present invention is directed a method of constructing a well and then production logging the unique well construction. More specifically, this invention is directed to a method of logging subterranean reservoirs though a unique well construction apparatus wherein the well fluid is flowed to surface via a separate conduit from the conduit where the logging operation is performed. | 08-05-2010 |
20110033355 | METHOD AND APPARATUS TO SEQUESTER CO2 GAS - The present invention is directed to methods to sequester oxides of carbon to prevent them from entering the atmosphere as gases. More specifically, this invention is directed to methods of chemical reactions and process to decompose carbon oxides by combustion of a metal fuel with carbon oxides using a regeneration process to recover the metal fuel. The process can optionally and beneficially be coupled to other useful chemical processes for the industrial purpose of sequestering carbon oxides into useful commercial chemicals and elements like carbon, chlorine, and sodium bicarbonate. | 02-10-2011 |
