20130206184 | MITIGATING SOLID ACCUMULATION ON A SUBMERGED SCREEN - Mitigating solid accumulation on a screen includes jetting water upstream through a portion of the screen while water simultaneously flows downstream through another portion of the screen. The water is jetted via at least one submerged nozzle. Several submerged nozzles may be present in an array on a moveable trolley. The submerged nozzles may be configured to provide warm or hot water or cold water having temperatures of less than 1° C. | 08-15-2013 |
20130206748 | MINERAL INSULATED SKIN EFFECT HEATING CABLE - Certain embodiments provide a heater. A heater device includes a skin effect component having at least one insulated electrical core conductor in electrical communication with an adjacent and substantially parallel, elongated ferromagnetic shape having a reduction and localization of the depth and width of the effective conductor path in the cross-section of the ferromagnetic wall; and, an inorganic ceramic insulation component. | 08-15-2013 |
20130220887 | TITANIA-BOUND ZEOLITE EU-2 COMPOSITION AND METHOD OF MAKING AND USING SUCH COMPOSITION - Catalyst composition useful in the catalytic dewaxing of a waxy hydrocarbon feedstock which catalyst composition includes a mixture of zeolite EU-2 and titania and may further include a noble metal. The zeolite EU-2 has a molar bulk ratio of silica-to-alumina (SAR) of greater than 100:1. The zeolite or mixture may have been dealuminated such as by acid leaching using a fluorosilicate salt or by steam treating. | 08-29-2013 |
20130224818 | METHOD FOR PREPARING A HYDROCARBON - A method for preparing a hydrocarbon comprising contacting a fatty acid substrate with at least one fatty acid reductase and at least one fatty aldehyde synthetase and at least one fatty acyl transferase, wherein the fatty acid substrate is a fatty acid, a fatty acyl-ACP, or a fatty acyl-CoA or a mixture of any of these, to obtain a fatty aldehyde; and contacting the fatty aldehyde with at least one aldehyde decarbonylase enzyme. | 08-29-2013 |
20130277111 | METHODS AND SYSTEMS FOR DRILLING - A method of automatically placing a drill bit used to form an opening in a subsurface formation on a bottom of the opening being formed comprises a) increasing a flow rate in a drill string to a target flow; b) controlling a flow rate of fluid into the drill string to be substantially the same as a flowrate of fluid out of the opening; c) allowing a fluid pressure to reach a relatively steady state; and d) automatically moving the drill bit toward the bottom of the opening at a selected rate of advance until an increase in measured differential pressure indicates that the drill bit is at the bottom of the opening. | 10-24-2013 |
20130277112 | METHODS AND SYSTEMS FOR DRILLING - A method of automatically picking up a drill bit off the bottom of an opening in a subsurface formation, comprises a) setting a predetermined level of differential pressure across a mud motor at which pickup of the drill bit is to be initiated; b) monitoring the differential pressure across the mud motor; c) allowing differential pressure across the mud motor to decrease to the predetermined level; and d) when the predetermined level is reached, automatically picking up the drill bit. | 10-24-2013 |
20130310621 | METHOD AND APPARATUS FOR REDUCING ADDITIVES IN A HYDROCARBON STREAM - A method for reducing one or more additives in a gaseous hydrocarbon stream ( | 11-21-2013 |
20140014375 | ENHANCED OIL RECOVERY METHODS FOR PRODUCING OIL FROM HEAVY OIL FIELDS - The present disclosure relates to enhanced oil recovery methods for highly viscous oil reservoirs containing large amounts of mobile water. One method includes injecting a carbon disulfide formulation or fluid into the formation via a first well and displacing the mobile water from the formation with the carbon disulfide fluid. The highly viscous oil is then solubilized using the carbon disulfide fluid, thereby generating a mixture of mobilized oil. The mixture of mobilized oil is then forced towards a second well and subsequently produced from the second well. | 01-16-2014 |
