摘要:
Method for generating a three-dimensional resistivity data volume for a subsurface region from an initial resistivity model and measured electromagnetic field data from an electromagnetic survey of the region, where the initial resistivity model is preferably obtained by performing multiple ID inversions of the measured data [100]. The resulting resistivity depth profiles are then registered at proper 3D positions [102]. The 3D electromagnetic response is simulated [106] assuming the resistivity structure is given by the initial resistivity model. The measured electromagnetic field data volume is scaled by the simulated results [108] and the ratios are registered at proper 3D positions [110] producing a ratio data volume [112]. A 3D resistivity volume is then generated by multiplying the initial resistivity volume by the ratio data volume (or some function of it), location-by location [114]. A related method emphasizes deeper resistive anomalies over masking effects of shallow anomalies.

摘要:
A method for designing a controlled-source electromagnetic survey that will discriminate between a defined deep marginal-interest reservoir (2) and specified false positive resistivity structures of concern (3, 4, 5). A reservoir model and a false positive model are constructed for each false positive scenario. The resistivity of the false positive model may be tuned to give electromagnetic data similar enough to the reservoir model when forward modeled that any differences fall in the model null space. A null-space discriminating ratio (“NSDR”) is defined, for example as the peak normalized difference of the two related modeled electromagnetic field data sets. An area coverage display of NSDR values (6) allows determination of such additional data as may be needed to distinguish the false positive body, and a survey design is developed accordingly (7). Reduction of the number of variables affecting the area coverage displays is a key feature of the method.

A portable assembly comprising a nylon flame retardant support rope, an adjustable size waist band and crotch harness and a lever controlled brake rope friction device. The user securely fastens the rope at the point of departure, threads the rope through the friction device and fastens the device to the harness. The lever on the friction device regulates the rate of descent from a full stop to the limiting rate prescribed by the friction ring assembly. Alternately, the user may hand hold the friction device for lowering a load fastened to the harness.

A thermal coupler assembly mounted to the coldfinger of a cryogenic cooler which provides improved thermal transfer between the coldfinger and the detector assembly mounted on the dewar endwell. The thermal coupler design comprises a stud and spring-loaded cap mounted on the coldfinger assembly. Thermal transfer is made primarily through the air space between the cap and coldwell walls along the radial surfaces. The cap is spring loaded to provide thermal contact between the cap and endwell end surfaces.

Systems and methods which provide electromagnetic subsurface mapping to derive information with respect to subsurface features whose sizes are near to or below the resolution of electromagnetic data characterizing the subsurface are shown. Embodiments operate to identify a region of interest (203) in a resistivity image generated (202) using electromagnetic data (201). One or more scenarios may be identified for the areas of interest, wherein the various scenarios comprise representations of features whose sizes are near to or below the resolution of the electromagnetic data (204). According to embodiments, the scenarios are evaluated (205), such as using forward or inverse modeling, to determine each scenarios' fit to the available data and further to determine their geologic reasonableness (206). Resulting scenarios may be utilized in a number of ways, such as to be substituted in a resistivity image for a corresponding region of anomalous resistivity for enhancing the resistivity image (207).
摘要:
The present invention relates to a washer fluid heater for operative connection to a coolant line of the engine cooling system of a vehicle, having a housing formed of a material of low to medium thermal conductivity, which together with end walls positioned in sealing relation thereto, at longitudinally opposite ends thereof, form a washer fluid chamber. Each of the end walls has a central opening of circular cross section. A central heating conduit, formed from a material of high thermal conductivity passes through the washer fluid chamber and through each of the central openings and is adapted for connection into the coolant line of a water cooled automobile engine. A first and a second annular grommets, each formed from a resilient material, are in sealing contact with a respective one of the central openings of the respective end walls. Each grommet has an inner opening dimmensioned to sealingly receive the heating conduit in throughpassing relation. There are additionally provided an inlet and an outlet, each positioned on the housing, adjacent a respective end wall, and in fluid communication with the washer fluid chamber. The inlet and outlet are adapted for connection, respectively, to the washer fluid supply line and the washer spray supply line.
