In another aspect, the invention provides a monitoring system for determining placement of a well treatment. Yet another aspect of the invention is an instrumented sand screen. Another aspect is a connector for routing control lines. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
摘要:
The present disclosure provides an engine assembly that is installed below the surface of the earth to harvest the thermal energy of the earth, using a working fluid in a closed loop system, and convert it into electricity, which can be commercialized at the surface. The subterranean engine comprises a hot region and a cold region, and a working fluid that moves between the two regions. The movement and efficiency of the working fluid operates the pistons that drive a generator coupled to the pistons, thereby generating electricity. The hot region of the engine is primarily powered by the geothermal energy. The engine can further incorporate renewable energy to improve the movement of the working fluid between the hot and cold regions. The system can further be used to store renewable energy below ground.
摘要:
An embodiment of a method for resolving features on a probe array is described that, comprises acquiring a plurality of micro-shifted images of a region of a probe array; reconstructing an image of the probe array using the micro-shifted images; and deriving intensity values for one or more probe features disposed on the probe array from the reconstructed image.
摘要:
A compensating multi layer material includes two compensating layers adjacent to one another. A multi-layer embodiment of the invention produces sub-wavelength near-field focusing, but mitigates the thickness and loss limitations of the isotropic “perfect lens.” An antenna substrate comprises an indefinite material.
摘要:
An apparatus to modify an incident free space electromagnetic wave includes a block of an artificially structured material having an adjustable spatial distribution of electromagnetic parameters (e.g., ∈, μ, η, σ, and n). A controller applies control signals to dynamically adjust the spatial distribution of electromagnetic parameters in the material to introduce a time-varying path delay d(t) in the modified electromagnetic wave relative to the incident electromagnetic wave.

摘要:
The present invention is directed towards methods and apparatus to release energy into wells using combustion of monopropellants. More specifically, this invention is directed to industrial methods to enhance the extraction of well fluids from wells by using the in-situ energy released from this inventions apparatus, methods, catalyst, and fluids blends for subterranean catalytic combustion of monopropellants.
摘要:
Gradient index lenses with no aberrations and related methods for making such lenses are described. In one aspect, a gradient index lens can be a substantially spherically-shaped lens that has at least one side that is flattened such that a locus of focal points resides on a plane. A method for making a gradient index lens can include forming material layers, each of the material layers defining an effective refractive index, and laminating the material layers together to form a substantially spherically-shaped lens having at least one side that is flattened to a substantially planar surface. The material layers can have a gradient refractive index distribution such that a locus of focal points resides on the substantially planar surface.
摘要:
The present invention comprises a system and methods to actuate downhole tools by transmitting an optical signal through an optical fiber to the downhole tool. The optical signal can comprise a specific optical signal frequency, signal, wavelength or intensity. The downhole tool can comprise packers, perforating guns, flow control valves, such as sleeve valves and ball valves, samplers, sensors, pumps, screens (such as to expand), chemical cutters, plugs, detonators, or nipples.
