| 20100243242 | METHOD FOR COMPLETING TIGHT OIL AND GAS RESERVOIRS - A method and apparatus for processing a subterranean formation comprising stimulating and fracturing a subterranean formation, and drilling the subterranean formation wherein the drilling and fracturing occurs without removing equipment for drilling from the formation. A method and apparatus for drilling and fracturing a subterranean formation, comprising a drill string assembly and a hydraulic fracturing system, wherein the drill string and fracturing system are in communication with a wellbore and wherein the drill string and a fracture formed by the hydraulic fracturing system are less than about 1000 feet apart. A method and apparatus for processing a subterranean formation comprising fracturing a subterranean formation using a hydraulic fracturing system and drilling the subterranean formation using a drill string assembly wherein the drilling and fracturing occurs without removing the drill string from the formation, and wherein the fracturing occurs via ports in the drill string assembly. | 09-30-2010 |
| 20100300688 | HIGH SOLIDS CONTENT METHODS AND SLURRIES - A composition and method are disclosed. The composition includes a carrier fluid and a solids mixture combined to form a slurry, wherein the solids mixture comprises a plurality of volume-averaged particle size distribution (PSD) modes, wherein a first PSD mode comprises solids having a volume-average median size at least three times larger than the volume-average median size of a second PSD mode such that a packed volume fraction of the solids mixture exceeds 0.75, and wherein the solids mixture comprises a degradable material and includes a reactive solid. The method includes circulating the slurry through a wellbore to form a pack in a fracture and/or a screen-wellbore annulus; degrading the degradable material to increase porosity and permeability of the pack; and producing a reservoir fluid through the permeable pack. | 12-02-2010 |
| 20100307750 | SQUEEZE COMPOSITION FOR RESTORING ISOLATION - The invention discloses a method of treating a wellbore, comprising the step mixing an alkali swellable polymer and a first material, wherein said first material does not cause said alkali swellable polymer to swell significantly; and placing said alkali swellable polymer and said first material in the wellbore. | 12-09-2010 |
| 20110005760 | SYSTEM AND METHOD FOR LOW DAMAGE FRACTURING - A method of fracturing a subterranean formation comprising at least in part shale formation, comprises providing a carrier fluid; providing a particulate blend including a first amount of particulates having a first average particle size between about 100 and 2000 microns and a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size, such that a packed volume fraction of the particulate blend exceeds 0.75; combining the carrier fluid and the particulate blend into a fracturing slurry; fracturing the formation with the fracturing slurry to create at least a fracture; and removing the second amount of particulates from the fracture. | 01-13-2011 |
| 20110024113 | VISCO-ELASTIC SURFACTANT SPACERS - A spacer for use in an oil well cementing operation comprises an aqueous solution of a visco-elastic surfactant.

| 20110042086 | ADDITIVE FOR CONTROLLING CEMENT SLURRY RHEOLOGY - A cement composition for use in a wellbore comprising a cement blend and at least two polyvinylalcohols wherein the polyvinylalcohols have different degrees of hydrolysis such that the rheology of the cement slurry capable of being formed from the composition is stable during temperatures changes. | 02-24-2011 |
| 20110098202 | SWELLABLE COMPOSITIONS FOR BOREHOLE APPLICATIONS - This invention relates to compositions which swell on contact with water. In particular, the invention is suitable for use in subterranean wells such as those used in the oil and gas industry. | 04-28-2011 |
| 20110155371 | HIGH SOLIDS CONTENT SLURRIES AND METHODS - A slurry and method are disclosed for low damage gravel packing. The slurry comprises a solids mixture comprising a plurality of volume-averaged particle size distribution (PSD) modes such that a packed volume fraction (PVF) exceeds 0.75; a carrier fluid in an amount to provide a solids volume fraction (SVF) less than the PVF of the solids mixture; and a stability additive to inhibit settling of the solids mixture. The method comprises circulating the slurry into a wellbore to deposit the slurry downhole; terminating the slurry circulation for a period of time, wherein the stability additive inhibits settling of the solids mixture; and thereafter circulating the deposited slurry in contact with a surface of a screen. Stability additives disclosed include colloidal particles, hydratable polymer particles, and particles having an aspect ratio above | 06-30-2011 |
| 20110155372 | HIGH SOLIDS CONTENT SLURRY METHODS - A method and system are disclosed for low damage gravel packing. The method comprises: combining a carrier fluid and a solids mixture into a slurry, wherein the solids mixture comprises a plurality of particle size distribution modes such that a packed volume fraction exceeds 0.75; contacting a screen with leak-off control agent to form a bridge; positioning the screen and circulating the slurry through the wellbore in any order such that the solids mixture is deposited between the screen and the wellbore; degrading the degradable material to increase porosity and permeability of the pack; removing the bridge; and producing a reservoir fluid from the formation. The system comprises the slurry, a tubing string and slurry pump to position the screen and circulate the slurry to form the bridge on the screen. | 06-30-2011 |
