摘要： A wellbore inspection device includes a radiation generation source operable to emit neutrons, and a radiation detector fixed relative to the radiation generation source and operable to detect backscattered neutron radiation from a surrounding environment. The radiation detector includes a plurality of individually addressable detector elements arranged in one or more concentric rings. Respective amounts of backscattered neutron radiation detected by the individually addressable detector elements within a ring is indicative of the azimuthal direction of the detected backscattered neutron radiation, and the respective amount of backscattered neutron radiation detected by the individually addressable detector elements of two or more concentric rings is indicative of an energy level of the backscattered neutron radiation. The inspection device determines whether a potential anomaly is present in or around the wellbore, based at least in part on the respective amounts of backscattered radiation detected by the individually addressable detector elements.

摘要： Hydrocarbons are exploited within a sedimentary basin using a stratigraphic simulation coupled with a hydrologic model and a terrestrial organic matter accumulation model. The inorganic sediment distribution within the basin is determined with a stratigraphic simulator for at least one time step. Then, at least one unsaturated zone is delimited within the basin using a hydrologic model. At least one zone of terrestrial organic matter accumulation within the basin and an amount of terrestrial organic matter accumulated in this accumulation zone are determined by a model of the terrestrial organic matter accumulation as a function of the unsaturated zone thickness, of the unsaturated zone thickness stability and of the surface water flux defined for the time step considered.

摘要： Systems and methods for simulating an effect of multiple seismic sources concurrently on a geologic formation are provided. Data is read from a seismic source file that describes at least two seismic source types. The concurrent propagation of acoustic energy from the at least two seismic sources types through the geologic formation is modeled. A seismic output file is then generated.

摘要： Systems and methods for detecting a sitting duck scenario of a vehicle on or near a road are disclosed. The current location and speed of the vehicle are used for different comparisons and/or determinations, including a comparison to road-specific information to determine whether the vehicle is in a particular proximity of a highway, and a determination whether the vehicle has been stationary continuously for at least a specified duration. Additional comparisons and/or determinations may be used. If such an occurrence has been detected, one or more notifications are generated, and provided to one or more of the vehicle operator and/or a remote computing server.

摘要： In an embodiment, a computer-implemented method of selecting locations in a field for treatment sampling is disclosed. The method comprises receiving, by a processor, input data including a number T of treatments applied to a field, a number L of treatment locations for each treatment, a list of treatment polygons within the field, and a map for the field indicating one or more values of a set of design parameters corresponding to environment factors for each of a plurality of locations in the field. The method also comprises computing, by the processor, an environment class index for each of a group of locations in the list of treatment polygons based on the map; distributing the list of treatment polygons to the T treatments based on the computed indices; and selecting, for each of the T of treatments, L treatment locations from the group of locations in the treatment polygons distributed to the treatment. In addition, the method comprises causing display of information regarding the selected treatment locations.
