Abstract: The subject fluid gauges measure actual position of a workpiece relative to a target position. A gauge body that is positionable relative to the workpiece and that includes multiple differential-pressure (DP) sensors has a measurement channel and respective reference channels. Each DP sensor measures, over a respective individual dynamic pressure range, a differential pressure established by a respective fluid flow in the measurement channel relative to a fluid flow in a respective reference channel. The dynamic pressure ranges of the DP sensors substantially overlap each other. A controller is connected to and monitors the DP sensors. The controller is configured to select, for obtaining a differential pressure indicative of the position of the workpiece, a DP sensor sensing the smallest magnitude of DP.

Abstract: A system and method are provided for automatically correlating geologic tops. The system receives well logs from different well bores and one or more user seed picks identifying a well top to be correlated. Each of the seed picks is added to a priority queue ordered by each pick's confidence. User selected picks are assigned the highest level of confidence. The system performs correlation by selecting a window of well log data about a user's manual pick, selected from the top of the priority queue, and then finding the best optimal match with a corresponding window in a neighboring wellbore. That new pick is then estimated in the target well using a correlation function. A quality value and a confidence value may then be calculated for each pick using some correlation function, for example dynamic time warping, and added to the priority queue according to the confidence value.

Abstract: The objective of the present invention is to obtain an MS2 spectrum for each of a plurality of different ion species even when their m/z values are extremely close to each other and prevent separate setting of each ion species as the precursor ion. In the vicinity of the target m/z, a precursor-ion selection window covering a predetermined m/z range (2×?M) is gradually shifted in predetermined steps (?m) to define a plurality of windows as the condition of the precursor-ion selection. When an MS2 analysis is performed on the same sample for each window, the intensities of the product-ion peaks which appear on the MS2 spectrum change with the change in the central m/z value of the window. From this intensity change, which of the plurality of ion species selected as the precursor ion is the origin of each product ion is determined. Based on the result of this determination, the product ions are sorted out and an MS2 spectrum is reconstructed for each ion species.

Abstract: A modified direct search Neighborhood Algorithm (NA), similar to genetic or evolutionary algorithms, is used for automatic calibration of Stratigraphic Forward Models (SFM) to data constraints. The modified NA comprises explicit escape clauses from local minima and admissible solutions, thereby preventing a natural tendency of conventional NAs to converge and oversample a single minimum. The density of models in parameter space is used to define local minima. Admissible solutions are defined by considering error thresholds taking into account that SFM may be imperfect and that calibration constraints may be uncertain. The modified NA algorithm obtains a plurality of geological scenarios that agree with the data, and which can be used for further analysis and prediction.
