摘要： Fractures are initiated or extended within an earth formation from a well which includes a tubing string extending to a wellbore space adjacent the fracture zone from a conventional wellhead. Carbon dioxide, nitrogen or a similar highly expansible fluid is pumped into the wellbore space and/or at least a portion of the tubing string at a pressure greater than the fluid critical pressure and greater than the fracture initiation or extension pressure required in the formation zone. A perforating gun is fired or a shear disk is actuated to release the expansible fluid to flow into the formation at an initial velocity and kinetic energy which substantially exceeds that which is obtained with water or similar conventional fracturing fluids so as to initiate or extend hydraulic fractures with a minimum radius of curvature with respect to the wellbore.

摘要： A method of initiating fractures in preselected zones by precooling the zones of interest. A cooling fluid is either circulated in a wellbore at the selected zone or injected into the selected zone. After cooling, conventional fracturing techniques are used, but fractures are more easily controlled by reduction of required pressures in the cooled zones.

摘要： In processes using electrical power to apply heat to a subsurface formation through a transmission well, power losses are reduced by installing in flowlines leading to the well one or more devices that electrically disrupts the flowline and that creates a tortuous flow path for liquids flowing through the device. The parts of the device contacting liquids are either fabricated of metal which is electrically insulated from the liquids or are fabricated of electrically nonconductive material. The device may be a free-wheeling hydraulic pump or motor, for example, a free-wheeling gear pump.

摘要： A borehole cementing process in which a quantity of water-like fluid is pumped into a borehole above drilling mud and the cement slurry is pumped into the borehole above at least a portion of the water-like fluid. Turbulent mixing of cement slurry and water at the interface creates an isolation zone preventing degradation of the bulk of the cement slug.

摘要： A stress gauge comprising a pair of substantially circular metal sheets welded together along their circumference, a metal tube in communication with the space between metal sheets, a pressure transducer attached to the metal tube and a slightly pressurized fluid filling the tubing and the space between the metal sheets. Liquid pressure is selected to provide a desired volume between the two plates, thereby providing a proper aspect ratio and preferably reducing the sensitivity of the gauge to temperature changes. When positioned in a solid ice sheet, pressure output indications from the pressure transducer are directly correlated to stress in the ice normal to the plane of the metal sheets.

摘要： Liquid wastes and slurries of ground solids wastes are injected into earth formation zones which have a fluid content of fluid similar to the liquid wastes or slurry which is below the irreducible saturation level for the liquid wastes or slurry to be injected. The formation may be non-hydrocarbon bearing or a depleted hydrocarbon bearing reservoir which has been depleted by enhanced fluid recovery techniques below its ambient irreducible fluid saturation value.

摘要： Slurried solid waste materials are injected into subterranean earth formations in a zone of interest which has a relatively low in situ compressive stress bounded by zones of higher in situ compressive stress and wherein the zone of interest has alternate layers of material of relatively high and low permeability to fluid flow, respectively. The solid waste slurry is conducted through an injection well penetrating the zone of interest to form a conventional two-winged hydraulic fracture. The fracture is extended by reducing the tendency to form filtercake in the fracture adjacent to the layers of material of relatively low permeability while depositing particle filtercake adjacent the earth layers of high permeability so as to provide clear fluid flowpaths through the fracture while allowing the filtercake layers disposed in the fracture to assist in propping the fracture open until adequate lateral extension of the fracture and disposal of the waste material is accomplished.

摘要： A relatively closely spaced injection well and production well pair is used as a single electrode and is used in a way that significantly increases the effective radius of an electrode production location. This is achieved by appropriately spacing of the wells and flowing aqueous fluid between wells at a pressure below the pressure driving oil toward the production well. The controlled pressure flowing aqueous fluid forms a highly conductivity flow path for oil flowing toward the production well. The effectiveness of the increased well pair drainage radius is achieved or augmented by injecting aqueous fluid, preferably steam or hot water, into the formation at a pressure great enough to drive oil toward the well pair and using the formation injection well as an electrode for electrically heating the oil. More than one well pair may be used either as a separate or the same electrode. One injection well or one production well may be used to form two or more well pairs. Several well pairs may be used in a suitable producing and injection pattern.

摘要： There is provided a well completion for electrical alternating current power transmission that minimizes power losses and related corrosion problems. Casing is used both as the electrode and conductor. Most of the conductor portion is made of nonmagnetic metal, for example aluminum, and is electrically insulated both exteriorly and interiorly. The insulation extends below the point where the nonmagnetic metal ends. Tubing is used to produce or inject fluids. The upper end of the conductor-electrode may be surrounded by a nonmagnetic surface string which is also electrically insulated.
