The redundant wired pip-in-pipe telemetry system includes an outer pipe and an inner pipe disposed within the outer pipe. Within the outer pipe, two or more conductive elements may be provided as well as a wired path controller that may selectably switch between available conductive paths. The wired path controller may identify conductive paths with good electrical characteristics and select those paths for transmission. If a conductive path develops a fault, the wired path controller may select one of the alternative redundant conductive paths for transmission to avoid the fault. The wireless controller may further transmit information about the location of faults to a drill operator at the surface.

  • Publication number: 20150027694
    Abstract: Embodiments of the present invention relate to heater patterns and related methods of producing hydrocarbon fluids from a subsurface hydrocarbon-containing formation (for example, an oil shale formation) where a heater cell may be divided into nested inner and outer zones. Production wells may be located within one or both zones. In the smaller inner zone, heaters may be arranged at a relatively high spatial density while in the larger surrounding outer zone, a heater spatial density may be significantly lower. Due to the higher heater density, a rate of temperature increase in the smaller inner zone of the subsurface exceeds that of the larger outer zone, and a rate of hydrocarbon fluid production ramps up faster in the inner zone than in the outer zone. In some embodiments, a ratio between a half-maximum sustained production time and a half-maximum rise time of a hydrocarbon fluid production function is relatively large.

  • Publication number: 20150027711
    Abstract: A system for disrupting convective heat flow within a body of hydrocarbonaceous material includes a body of hydrocarbonaceous material which is sufficiently porous that convective currents can form in void spaces of the material. A bulk fluid occupies these void spaces and the bulk fluid is heated by a heat source, causing the bulk fluid to flow through the void spaces in convective currents. A convective barrier is placed in an upper portion of the body of hydrocarbonaceous material. This convective barrier is configured to disrupt convective flow of the bulk fluid.

  • Publication number: 20150021031
    Abstract: Methods and systems relate to steam assisted oil recovery utilizing a fired boiler and an electric boiler, which may be disposed closer to an injection well than the fired boiler. A gas turbine produces electricity supplied to the electric boiler and flue gas exhaust that may input into the fired boiler. The electric boiler may vaporize condensate that forms from the steam generated in the fired boiler prior to being introduced into the injection well.

  • Publication number: 20150000899
    Abstract: Methods, systems, devices, and products for taking a downhole measurement are presented. The method may include cooling a sensor in a borehole intersecting an earth formation using an electrocaloric material associated with the sensor, wherein the sensor is responsive to a downhole parameter. The method may further include applying an electric field to the electrocaloric material to generate a giant electrocaloric effect. The method may include selecting dimensions, composition, and Curie temperature of the electrocaloric material and characteristics of the electric field sufficient to reduce the nominal temperature of the sensor by at least 20 degrees Celsius, which may result in the sensor being proximate to a target temperature within the nominal operational temperature range of the sensor.

  • Patent number: 8899326
    Abstract: An oil recovery process entails recovering an oil-water mixture from an oil bearing formation and separating the oil-water mixture to produce an oil product and produced water. The produced water includes suspended and dissolved solids and is subjected to treatment which removes suspended and dissolved solids therefrom. The treated water is then directed to a forced circulation steam generator that includes a furnace having a burner, water cooled walls and an evaporator unit. The treated water is pumped through the water cooled walls and the evaporator unit. The water passing through the water cooled walls and evaporator unit are heated to produce approximately 10% to approximately 30% quality steam in both the water cooled walls and the evaporator unit. The steam is collected and separated from a water-steam mixture to produce high quality steam, on the order of 95% or greater quality steam.
