| 20110284027 | METHODS FOR GRANULAR SCAVENGER MATERIAL TRANSFER - A method for cleaning a reactor, the method including circulating a fluid inside the reactor, pumping the fluid from the reactor into an inlet of a tank cleaner, and removing solids from the fluid to produce a clean fluid. The method further includes transferring the clean fluid to the reactor and transferring pneumatically the removed solids to a pressurized vessel. Also, a method for transferring spent granular material, the method including providing a vacuum system disposed at a hydrocarbon production site to remove spent material from a reactor, transferring the spent material through the vacuum system into a pressurized vessel, and conveying pneumatically the spent material from the pressurized vessel to a second pressurized vessel. | 11-24-2011 |
| 20110220354 | POLYMER GELS AS FLOW IMPROVERS IN WATER INJECTION SYSTEMS - A water injection system that includes a primary water injection line; an injection fluid supply tank; a high pressure injection pump in fluid communication with the injection fluid supply and primary water injection line for pumping injection fluid in injection fluid supply tank through the primary water injection line; a polymer gel supply tank; and a high pressure chemical injection pump in fluid communication with the polymer gel supply tank and the water injection line configured to pump polymer gel having a viscosity of at least about 50,000 cP (at 20° C. measured using a Bohlin Rheometer CSR 50, cone and plate measuring system CP 4°/40 mm, single shear rate 1/s) in the polymer gel supply tank into the water injection line for mixture with injection fluid is disclosed. | 09-15-2011 |
| 20110192595 | METHOD AND APPARATUS FOR MEASURING PARTICLE SIZE DISTRIBUTION IN DRILLING FLUID - A method for measuring particle size distribution in a fluid material, involving inserting a laser beam instrument directly in the fluid flow line, wherein the laser beam instrument focuses a laser beam on a window directly coupled with the fluid flow line, wherein the fluid flow line comprises a fluid having a plurality of particles of different sizes, measuring a diameter of at least one particle in the fluid flow line by reflectance of the at least one particle as the at least one particle passes through the focused laser beam, and determining a duration of reflection of the at least one particle, and obtaining a count of particles in each of a pre-set range group of particle sizes, wherein the count of particles is used to determine particle size distribution in the fluid flow line. | 08-11-2011 |
| 20110190438 | METHOD OF IMPROVING THE COLD FLOW PROPERTIES OF A PARAFFIN-CONTAINING FLUID - A method of improving the cold flow properties of a paraffin-containing fluid that includes admixing an effective amount of a polymer comprising cyclic amide and long chain alkyl functionality is disclosed. | 08-04-2011 |
| 20110162838 | SYSTEM AND METHOD FOR PROPPANT TRANSFER - A method of transferring proppant materials, wherein the method includes providing a first pressurized container ( | 07-07-2011 |
