摘要： The disclosed embodiments include systems and methods to evaluate a formation dip of a formation bedding. The system includes memory configured to store a color image indicative of a log of a formation bedding. The system also includes a processor configured to execute instructions to filter colors of the color image to determine one or more cusps of the formation dip, and cross correlate a reference wave with the one or more cusps of the formation dip to match curvatures of the reference wave with the one or more cusps of the formation dip illustrated in the color image, wherein the curvatures of the reference wave are based on one or more parameters of the formation bedding. The processor is further operable to generate a wave that matches the one or more cusps of the formation dip with the reference wave, where the wave is indicative of the formation dip.

摘要： A method for obtaining accuracy gravity coefficients out of three orthogonally oriented accelerometer devices and a thermometer by computing, using a pre-programmed micro-control unit processor, temperature errors, bias error coefficients, sensitivity error coefficients, and orthogonality error coefficients during measurement while drilling operations. Particularly, the method uses voltage data values of the three orthogonally oriented accelerometers to compute said error coefficients which provides for zero-error positioning of the MWD tool during long-term downhole surveying as well as while facing high-shock, vibrations, and high temperatures.

摘要： Systems, apparatus and methods are described for purposes of initiating a response to detection of an adverse operational condition involving a system including a drill rig and an inground tool. The response can be based on an uphole sensed parameter in combination with a downhole sensed parameter. The adverse operational condition can involve cross-bore detection, frac-out detection, excessive downhole pressure, a plugged jet indication and drill string key-holing detection. A communication system includes an inground communication link that allows bidirectional communication between a walkover detector and the drill rig via the inground tool. Monitoring of inground tool depth and/or lateral movement can be performed using techniques that approach integrated values. Bit force based auto-carving is described in the context of an automated procedure.

摘要： A method for geosteering while drilling a well in a subterranean formation using a downhole assembly having a toolface comprises measuring at least one motion-related downhole parameter relative to the toolface angle so as to generate azimuthally-associated data, using the azimuthally-associated data to assess formation anisotropy, and using the anisotropy assessment to manually or automatically steer a well while drilling the well. The motion-related downhole parameter may relate to motion of an asymmetric bit or bent housing or bent housing section. The downhole parameter may be selected from the group consisting of angular velocity, angular acceleration, tangential acceleration, radial acceleration, axial acceleration, cross-axial acceleration, total acceleration, high-frequency torsional oscillation (HFTO) severity, band-pass-filtered root-mean-square (RMS) acceleration, band-pass-filtered peak acceleration and the azimuthally-associated data may comprise azimuthally-associated measurements of any of the motion-related parameters and/or azimuthally-associated calculations of compressive strength, Young's modulus, Poisson's ratio, stress, and fracture measurement.

摘要： System and methods for geosteering inversion are provided. A downhole tool's response along a path of a wellbore to be drilled through a formation is predicted over different stages of a downhole operation, based on each of a plurality of initial models of the formation. Each initial model represents a different number of formation layers over a specified range. The tool's actual response with respect to one or more formation parameters is determined, based on measurements obtained during a current stage of the operation. The actual response is compared with that predicted from each of the initial models. At least one of the models is selected as an inversion model, based on the comparison and a selection criterion. Inversion is performed for subsequent stages of the operation along the wellbore path, based on the selected model. The wellbore path is adjusted for the subsequent stages, based on the inversion results.

摘要： Methods and systems are provided for characterizing a subterranean formation that involve the generation of a 3D geological model of the formation. The 3D geological model can be used in conjunction with a fluid-flow simulator to generate a first 3D resistivity distribution. A second 3D resistivity distribution can be generated based on electromagnetic survey data of the formation. The 3D geological model can be updated based on differences between the first and second 3D resistivity distributions. The simulation and subsequent update to the 3D geological model can be repeated until differences between the first and second 3D resistivity distributions satisfy a stopping criterion. Data characterizing properties of the formation can be extracted from the resulting 3D geological model. The operations can be performed in conjunction with time-lapsed EM measurements before and after subjecting the formation to a production process and the extracted data can be analyzed to identify variations (such as fractures) in the formation that result from the production process.
