The viscous dissolving fluids used according to the invention are acid-fracturing treatment fluids containing a dissolving agent viscosified with a material such as a viscoelastic ... 08/30/07 - 20070199706 - Enhanced hydrocarbon recovery by convective heating of oil sand formations The present invention involves a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by convective heating of the oil sand formation and the heavy oil and bitumen in situ by a downhole electric heater. Multiple propped vertical hydraulic fractures are constructed from the well bore into ... 08/30/07 - 20070199705 - Enhanced hydrocarbon recovery by vaporizing solvents in oil sand formations The present invention involves a method and apparatus for enhanced recovery of petroleum fluids from the subsurface by injecting a hydrocarbon solvent vapor in contact with the oil sand formation and the heavy oil and bitumen in situ. Multiple propped vertical hydraulic fractures are constructed from the well bore into ... 08/16/07 - 20070187096 - Organic acid compositions and methods of use in subterranean operations Subterranean treatment fluids comprising one or more organic acids and methods of use in subterranean operations are provided. In one embodiment, the methods comprise: providing a treatment fluid that comprises an aqueous base fluid, a gelling agent, and one or more organic acids; and contacting a subterranean formation with the ... 06/14/07 - 20070131423 - Method of extracting hydrocarbons A mixture of liquefied carbon dioxide (above about 20 percent) and methanol (less than about 80 percent) is injected into an oil and gas well to fracture the oil bearing formation at suitable pressures. In a second and other following stages, a proppant mixed with a polymer is injected to ... 06/14/07 - 20070131422 - Sand aggregating reagents, modified sands, and methods for making and using same A method for treating solid materials is disclosed, where the treating compositions coats surfaces or portions of surfaces of the solid materials changing an aggregation or agglomeration propensity of the materials. Treated solid materials are also disclosed. The methods and treated materials are ideally suited for oil field applications. ... 05/24/07 - 20070114028 - Fracturing of subterranean formations Fracturing of a subterranean formation may be achieved using a hydrogel. A preferred gel is formed from a gel precursor formulation which comprises an aqueous formulation of poly(1,4-di(4-(N-methylpyridinyl))-2,3-di(4-(1-formylphenyl)butylidene), poly (vinyl alcohol) and a suitable proppant, in the presence of an acid catalyst. The gel may be prepared at the surface ... 05/10/07 - 20070102155 - Propped fracture with high effective surface area Propped fractures in formations from which fluids are produced are described that have wormholes extending out into the formations from the faces of the fractures at locations distant from boreholes. Methods are given for creating such propped fractures having wormholes in which either a closed propped fracture is formed and ... 12/21/06 - 20060283591 - Degradable fiber systems for stimulation A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given. The method includes using fibers to aid in transporting, suspending and placing proppant or gravel in viscous carrier fluids otherwise having insufficient viscosity to prevent particulate settling. Fibers are ... 06/15/06 - 20060124303 - Low-quality particulates and methods of making and using improved low-quality particulates A method of treating a subterranean formation, comprising: at least partially coating particulates with a first layer of a first curable resin and allowing the first curable resin to substantially cure; and then, at least partially coating the particulates with a second layer of a second curable resin; and allowing ... 06/01/06 - 20060113077 - Degradable material assisted diversion or isolation A method for well treatment by forming a temporary plug in a fracture, a perforation, a wellbore, or more than one of these locations, in a well penetrating a subterranean formation is provided, in which the method of well treatment includes: injecting a slurry comprising a degradable material, allowing the ... 03/30/06 - 20060065397 - Methods and compositions for inducing tip screenouts in frac-packing operations A method of inducing tip screenout during a frac-packing treatment comprising injecting a proppant slurry into a subterranean formation, wherein the proppant slurry comprises a proppant material, a fracturing fluid, and degradable particulates and wherein the degradable particulates physically interact with themselves and with the proppant material to aid in ... 01/19/06 - 20060011342 - Fluid loss control additives for use in fracturing subterranean formations The present invention relates to subterranean fracturing operations, and more particularly to fracturing fluids that include an improved fluid loss control additive, and methods of using such fracturing fluids in fracturing subterranean formations. An example of a method of the present invention is a method of fracturing a subterranean formation. ... 01/05/06 - 20060000609 - Matrix acidizing high permeability contrast formations A method for stimulating thick or multilayered heterogeneous or homogeneous formations in a single trip without packers involves perforating with tubing conveyed perforation, then injecting a self-diverting acid, then moving the tubing string and perforating at a new location, and then injecting additional self-diverting acid. The sequence may be repeated. ... 11/17/05 - 20050252659 - Degradable additive for viscoelastic surfactant based fluid systems A method is given for treating a subterranean formation penetrated by a wellbore with a viscosified fluid. The fluid contains a solid hydrolysable polyacid that upon dissolution and hydrolysis releases an acid that is a breaker for the viscosifying system. Suitable solid hydrolysable polyacids include polylactic acid and polyglycolic acid. ... ### FreshPatents.com Support |
