20130319653 | WEDGE DEFLECTING DEVICE FOR SIDETRACKING - A wedge deflecting device useful in drilling and workover operations on oil and gas wells. The device includes a cutting tool connected to the upper portion of the wedge by means of the shear element provided with an external circular groove, located below the wedge deflecting surface, and with a transverse slot in its upper part, the cutting tool having a longitudinal cylinder and a downwards spring-biased piston, inserted into the cylinder; above lower seal elements and below the spring the piston has a wedge nose which corresponds to a transverse slot of the shear element. Below the piston, the cylinder communicates with the drill string and the supply tube, and above-the-piston space communicates with the borehole interior. The cutting tool is provided with a radial inward spring-biased locking element, arranged to be able to fix the piston in its top position, where the piston is located above the shear element. | 12-05-2013 |
20130327526 | EXPANDABLE SAND SCREEN AND METHOD FOR WELL CASING FOR THERMAL OIL RECOVERY - A method of well casing permitting thermal oil recovery includes drilling a wellbore to the top of productive formation, casing the wellbore with a casing string, drilling through the productive with a smaller diameter bit, running in a sand screen to the productive formation and subsequent drainage or heat carrier injection into the formation. The sand screen contains longitudinally-corrugated pipes with slots, mutually connected by the end cylindrical portions with a limited longitudinal shift possibility. Besides, the sand screen slots are internally hermetically sealed with a thermoplastic material. Running-in of the screen down to the target depth, include creating an internal excess pressure to expand the sand screen along its entire length except for cylindrical sections, fixing and hermetical anchoring to the casing. Pumping-in of a heat-carrier, under influence of which the thermoplastic material melts up, unseals the slots. | 12-12-2013 |

20130280725 | FLUIDIC DEVICES FOR BIOSPECIMEN PRESERVATION - The present invention relates to fluidic devices for preparing, processing, storing, preserving, and/or analyzing samples. In particular, the devices and related systems and methods allow for preservation or storage of samples (e.g., biospecimen samples) by using one or more of a bridge, a membrane, and/or a desiccant. | 10-24-2013 |
20130281316 | SLIP-INDUCED COMPARTMENTALIZATION - The present invention relates to fluidic devices for compartmentalizing samples. In particular, the devices and related systems and methods allow for compartmentalization by using one or more first chambers connect by a first channel (e.g., where the cross-sectional dimension of the first channel is less than the cross-sectional dimension of at least one first chamber). | 10-24-2013 |
20130309679 | FLUIDIC DEVICES AND SYSTEMS FOR SAMPLE PREPARATION OR AUTONOMOUS ANALYSIS - The present invention relates to fluidic devices for preparing, processing, storing, preserving, and/or analyzing samples. In particular, the devices and related systems and methods allow for preparing and/or analyzing samples (e.g., biospecimen samples) by using one or more of capture regions and/or automated analysis. | 11-21-2013 |

20130199968 | MILD HYDRODESULFURIZATION INTEGRATING GAS PHASE CATALYTIC OXIDATION TO PRODUCE FUELS HAVING AN ULTRA-LOW LEVEL OF ORGANOSULFUR COMPOUNDS - Desulfurization of hydrocarbon feeds is achieved by first contacting the entire feed with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions; a flashing column downstream of the hydrodesulfurization reaction zone fractionates the effluent to obtain a first fraction which contains refractory organosulfur compounds and a second fraction that is substantially free of organosulfur compounds, since the organosulfur compounds boiling in the range of this fraction were the labile organosulfur compounds which were initially removed by mild hydrodesulfurization. The first fraction is contacted with a gaseous oxidizing agent over an oxidation catalyst having a formula Cu | 08-08-2013 |
20140197074 | TARGETED DESULFURIZATION PROCESS AND APPARATUS INTEGRATING GAS PHASE OXIDATIVE DESULFURIZATION AND HYDRODESULFURIZATION TO PRODUCE DIESEL FUEL HAVING AN ULTRA-LOW LEVEL OF ORGANOSULFUR COMPOUNDS - Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula Cu | 07-17-2014 |
