摘要： Systems and methods for automated security inspection and routing of in-transit objects are described. In one embodiment, a plurality of security screening devices are provided, each operable to output screening data of an in-transit object, including a first screening device located in a sealed environment of a vehicle for transporting the object towards a conveying system, including one or more measuring devices operable to measure screening parameters of the object when located in the sealed environment, and a second screening device in combination with conveying and routing components of the conveying system used to transport said objects from an ingress point through a conveyor junction to reach the second screening device. A control unit is assigned to the conveyor junction, wherein the control unit is configured to receive security data assigned on the basis of the screening data from the first screening device to the object upstream of the conveyor junction, and in response, to determine and set a routing direction on the basis of the assigned security data, whereby the object is directed downstream to a screening route for further screening by the second screening device, or to a loading route for objects cleared for loading. Other embodiments are also described and claimed.

摘要： An x-ray based litho-density tool for measurement of simultaneous invaded and non-invaded formation surrounding a borehole is provided, the tool including at least an internal length comprising a sonde section, wherein sonde section further includes an x-ray source; at least one radiation measuring detector; at least one source monitoring detector; and a plurality of sonde-dependent electronics. In various embodiments, the tool uses x-rays to illuminate the formation surrounding a borehole, and a plurality of detectors are used to directly measure both invaded and non-invaded formation bulk densities. Detectors used to measure borehole standoff such that other detector responses may be compensated for tool standoff; long and ultra-long space detectors disposed in electromagnetic communication with a source located within a collimated tungsten radiation shield; and wear-pads disposed such that the source and detector assembly may be pressed against the side of the borehole to reduce borehole effects are also provided.

摘要： Systems and methods for determining the composition of an earth formation are disclosed. One or more spectra that correspond to gamma radiation that is detected at each of multiple depths in a wellbore are generated, the contributions of each of multiple detection elements to the one or more spectra are determined, and the weight fractions of each of multiple compounds that are associated with the detection elements are calculated. The weight fraction calculations are based on a number density ratio value for the compound's associated detection element, which allows the weight fraction to be calculated directly from the contribution of the compound's associated detection element without a normalization factor.

摘要： A downhole segmented radiation detector tool measuring formations surrounding a borehole is provided, the tool including at least a plurality of segments capable of detecting radiation, wherein the segments return to the tool after interacting with material surrounding the tool; and radiation shielding configured to allow radiation directly from a radiation source to pass internally through the downhole tool to a reference segment. A method of measuring formations surrounding a borehole is also provided, the method including at least: lowering a downhole tool into a borehole surrounded by a subterranean formation; detecting a first plurality of X-rays or gamma-rays that return to the downhole tool after interacting with materials surrounding the downhole tool using a first segment of an array segmented radiation detector; and configuring associated radiation shielding to allow radiation directly from a radiation source to pass internally through the downhole tool to the reference segment.

摘要： A system for generating eccentering corrected response includes a logging tool configured to examine a material filled in an annular space to generate a tool response. The material is filled in an annular space formed by an outer conduit and an inner conduit disposed in the outer conduit. The logging tool is disposed in an inner conduit. The tool response includes scattered gamma ray photon counts distorted by a radial shift of the logging tool. The system includes a data transmission device coupled to a plurality of detectors and configured to transmit data detected by the plurality of detectors. The system also includes a computer processor linked to the data transmission device and configured to receive the tool response. The computer processor is configured to process the tool response and generate an eccentered corrected response by correcting effects of the radial shift in the tool response using eccentering correction technique.

摘要： A radiation logging tool is provided that includes a scintillator detector for use on a wellbore tool string to characterize earth formations. The scintillator detector has a shutter to allow for the collection of data differentiating between incident radiation, such as backscatter signal, and system noise, such as dark current, vibration noise, electronics thermal noise, and electrostatic noise. The radiation logging tool provides for a method of calibrating and measuring incident radiation by the removal of system noise. The shutter is positioned between the photosensor and scintillation member of the scintillator detector, and is able to switch between open and closed states while the scintillation detector is deployed. Measurements of signal noise can be used to calibrate the sampling signal of incident radiation on the scintillator detector.
