Abstract: A compensating of the sensor module occurs with the implementing of the transfer function in the measuring circuit of the sensor module. The transfer function generates sensor measured values as a function of primary signal. In a later sensor calibration, sensor measured values provided on the sensor module interface are registered as a function of supplied pressure values and stored in a calibration database. In a later electronics module calibration, measured value signals provided on the signaling interface are registered as a function of sensor measured values supplied by means of a calibration signal source and stored in a calibration database, wherein the supplied sensor measured values correspond to the sensor measured values of the sensor calibration. Finally, there follows the calibration protocol creation, in which the measured value signals ascertained in the electronics module calibration are associated with the pressure values supplied in the sensor calibration.

Abstract: The disclosure presents processes to generate look ahead data to guide borehole operations, such as drilling operations. The processes can array collected resistivity data around a representation of an active borehole. The array can be in various patterns, such as an interleaved helix pattern. Each slice of data from the collected resistivity data can be positioned and oriented corresponding to the central point depth parameter for each slice of data. A selection of one or more card views can be enabled to display details of the collected resistivity data corresponding to the selected slice of data. An analysis of the resistivity data can generate an identification of a boundary, such as an object or a subterranean formation change, in the subterranean formation look ahead portion of the active borehole. The boundary identification can be used as inputs to a borehole operation plan or to a geo-steering system.

Abstract: Described herein is a method and system for classifying rock types in a rock body. The method comprises the steps of obtaining spectral data from a spectral measurement (202) of a surface region of the rock body and then determining a first spectral ratio between two wavelength bands of the spectral data. From the first spectral ratio it can be assessed (204) whether the measurement is a high-angle measurement, and if the measurement is not a high-angle measurement then a further spectral ratio between two further wavelength bands of the spectral data is determined (208). The further spectral ratio is then compared (210) with a corresponding diagnostic criterion to assess whether the surface region comprises a first rock type associated with the further spectral ratio and diagnostic criterion.
