| 20120111566 | APPARATUS AND METHOD FOR STIMULATING SUBTERRANEAN FORMATIONS - A method of stimulating a subterranean formation using a tubular member with one or more burst disks therein. | 05-10-2012 |
| 20120071371 | AQUEOUS PARTICULATE SLURRY COMPOSITIONS AND METHODS OF MAKING SAME - A sand slurry composition and a method for making sand slurries are disclosed. The sand slurry composition is comprised of sand, an aqueous liquid and a chemical compound that renders the surface sand of hydrophobic. The method is comprised of rendering sand surface hydrophobic during or before making the slurry. This method and composition can find many applications in different industries, especially in various oil field applications. | 03-22-2012 |
| 20120037366 | BURST DISK-ACTUATED SHAPED CHARGES, SYSTEMS AND METHODS OF USE - One or more burst disks, for isolating downhole communication between a tubular and a hydrocarbon-bearing formation, are fit with a shaped explosive charge. Detonation of the shaped charge is initiated by the rupture of the burst disk. In a system for stimulating the formation, one or more sets of two or more shaped charge, enhanced burst disks are located at a location along the tubular corresponding to a selected interval for stimulation. The enhanced burst disks can be fit with a chamber of known pressure for establishing a known and significant pressure differential across the burst disk for enabling substantially simultaneous rupture at the selected interval. | 02-16-2012 |
| 20110315380 | SYSTEM FOR CEMENTING TUBULARS COMPRISING A MUD MOTOR - A method and system for cementing a tubular and mud motor in a wellbore utilizing burst disks above the mud motor. The burst disks rupture to permit the cement to flow through the burst disks and bypass the mud motor. All of the burst disks reliably rupture at a predetermined and known threshold pressure so as to permit cement to be pumped at a desired rate through all of the ruptured burst disks. Each burst disk is provided with a cover for maintaining a chamber of a known pressure between the cap and the burst disk. All of the burst disks predictably and reliably rupture at the rated pressure. | 12-29-2011 |
| 20110186297 | APPLICATIONS OF SMART FLUIDS IN WELL SERVICE OPERATIONS - Smart fluid compositions and methods of use in the well service operations. | 08-04-2011 |
| 20110100715 | CENTER DISCHARGE GAS TURBODRILL - A compact gas turbine motor and a speed reduction transmission capable of providing the speed and torque required for drilling with center discharge bits. The transmission includes two sun gears of different pitch diameters, keyed to the turbine shaft. Upper planet gears, whose carrier is fixed in place, drive an outer ring gear, which engages lower planet gears having a different pitch diameter. The lower planet gears engage the lower sun gear. Due to the different pitch diameters of the sun gears and planet gears, the gear carrier for the lower planet gears rotates in the same direction as the turbine shaft, but at a much slower rate. Exhaust gas from the turbine can be directed through one or more flow restriction elements to increase gas density in the turbine, further reducing turbine speed. The flow restriction element can comprise a venturi, to provide a vacuum assist to remove cuttings. | 05-05-2011 |
| 20110011589 | Well Service Compositions for Consolidation of Particulates in Subterranean Coal Seams - A method of agglomerating coal particles in a subterranean formation having a coal seam, comprising the steps of providing (a) a fluid having an aqueous medium and a first collector and/or a frother; (b) pumping the fluid into the formation and (c) contacting coal particles in the formation thereby agglomerating the contacted coal particles. | 01-20-2011 |
| 20100267593 | CONTROL OF PARTICULATE ENTRAINMENT BY FLUIDS - An aqueous slurry composition for use in industries such as petroleum and pipeline industries that includes: a particulate, an aqueous carrier fluid, a chemical compound that renders the particulate surface hydrophobic, and a small amount of an oil. The slurry is produced by rendering the surface of the particulate hydrophobic during or before the making of the slurry. The addition of the oil greatly enhances the aggregation potential of the hydrophobically modified particulates once placed in the well bore. | 10-21-2010 |

The sand slurry composition is comprised of sand, an aqueous liquid and a chemical compound that renders the surface sand of hydrophobic. The method is comprised of rendering sand surface hydrophobic during or before making the slurry. This method and composition can find many applications in different industries, especially in various oil field applications. | 08-12-2010 |
| 20100084134 | FRACTURING METHOD AND APPARATUS UTILIZING GELLED ISOLATION FLUID - A method and apparatus for fracturing a formation containing a wellbore comprising the steps of (a) injecting a gel into the wellbore; (b) permitting the gel to increase in viscosity and (c) fracturing the formation in the vicinity of the gel. | 04-08-2010 |
| 20080210424 | Apparatus and Method of Fracturing - A method and apparatus for fracturing a formation containing a wellbore comprising the steps of (a) injecting a gel into the wellbore; (b) permitting for the gel to increase viscosity and (c) fracturing the formation in the vicinity of the gel. | 09-04-2008 |
