  • Patent number: 10670563
    Abstract: A calibration system for an electromagnetic (EM) tool includes a processor. The processor employs the EM tool to measure responses at each of a plurality of channels. The processor records the measured responses at each of the channels in an EM data log for the channel. The processor determines a nominal value of each of the channels, as being equal to a histogram peak of the EM data log. The processor selects one or more calibration points from the EM data log for a particular channel, based on a difference between the nominal value of the particular channel and the measured response at the calibration point being greater than a particular threshold. The processor determines a plurality of parameters by reducing a misfit between synthetic data and both the nominal values of the channels and the measured responses of the channels at the selected one or more calibration points.

  • Patent number: 10352161
    Abstract: A downhole tool operable to pump a volume of contaminated fluid from a subterranean formation during an elapsed pumping time while obtaining in-situ, real-time data associated with the contaminated fluid. The contaminated fluid includes native formation fluid and oil-based mud (OBM) filtrate. A shrinkage factor of the contaminated fluid is determined based on the in-situ, real-time data. The contaminated fluid shrinkage factor is fit relative to pumped volume or pumping time to obtain a function relating the shrinkage factor with pumped volume or elapsed pumping time. A shrinkage factor of the native formation fluid is determined based on the function. A shrinkage factor of the OBM filtrate is also determined. OBM filtrate volume percentage is determined based on the shrinkage factor of the native formation fluid and the shrinkage factor of the OBM filtrate.

  • Patent number: 10345465
    Abstract: Techniques involve obtaining acoustic data (including waves reflected from the casing, the annular fill material, the formation, and/or interfaces between any of the mud, the casing, and the annular fill material) from an acoustic logging tool. Techniques include normalizing the acoustic wave to result in a normalized wave having a comparable spectral shape with a reference wave, and comparing the normalized wave with the reference wave. The reference wave may be generated or modeled or produced from a look-up table or database, and may be estimated based on initial estimates of wellbore parameters. Based on the comparison of the normalized wave with the reference wave, a best-fit reference wave substantially matching the normalized wave may be identified. The best-fit reference wave may correspond with a thickness of the casing, an acoustic impedance of the annular fill material, and an acoustic impedance of mud.

  • Patent number: 10337313
    Abstract: In one example, an integrated well survey management and planning tool is implemented by a computer system. The tool can receive survey data describing a well being drilled from a surface to a subterranean geological target to be reached by drilling the well. The well is associated with a target trajectory on which the well is to be drilled from the surface to the subterranean geological target. Based, at least in part, on the survey data and the target trajectory, the tool determines an uncertainty indicator indicating an uncertainty in drilling the well on the target trajectory, and displays the uncertainty indicator in a user interface.

  • Patent number: 10330818
    Abstract: Various resistivity logging tools, systems, and methods are disclosed. At least some system embodiments include a logging tool and at least one processor. The logging tool provides transmitter-receiver coupling measurements that include at least direct coupling along the longitudinal tool axis (Czz), direct coupling along the perpendicular axis (Cxx or Cyy), and cross coupling along the longitudinal and perpendicular axes (Cxz, Cyz, Czx, or Czy). The processor combines a plurality of the coupling measurements to obtain inversion parameters. Based at least in part on the inversion parameter, the processor performs an inversion process to determine a vertical conductivity and, based in part on the vertical conductivity, determines borehole corrected values for said transmitter-receiver coupling measurements. One or more of the borehole corrected values can be provided as a function of borehole position.

  • Patent number: 10317204
    Abstract: A near-bit dynamic well deviation angle measurement apparatus includes a circuit board and 2n+1 accelerometers. One accelerometer is installed in an axial direction of a drilling tool and forms n sets of three-axis orthogonal installation together with other 2n accelerometers. The accelerometer installed in the axial direction measures Az?, and the remaining accelerometers respectively measure n X-axis radial components and n Y-axis radial components corresponding to the n X-axis radial components. A filter and a data processing unit are integrated on the circuit board. The circuit board acquires signals in which the components are eliminated by the accelerators in real time, and further high-frequency vibration and impact interference in the signals are filtered out by using the filter to obtain non-interference gravitational acceleration components Ax, Ay and Az, and further a well deviation angle is calculated.

  • Patent number: 10288766
    Abstract: A computer-based method of conditioning reservoir model data includes performing a modeling process within a 3D stratigraphic grid to generate an initial model including one or more facies objects within the model volume, the modeling process including parametric distributions, initial and boundary conditions as well as depositional and erosional events to define the facies objects within the model volume. The mismatch between this initial model and the conditioning well data and potential input trend model is applied to compute a locally variable constraint model. The method further includes executing a multiple point statistics simulation with this constraint model that varies between completely constrained by the initial model at locations where the initial model is consistent with known well data and potential input trend models, and unconstrained by the initial model at locations where the initial model does not match known well data or potential input trend models to allow conformance to the known data.

  • Patent number: 10287878
    Abstract: In some aspects, injection fluid is flowed into a closed wellbore in a subterranean region. Wellbore pressure in response to flowing the injection fluid into the closed wellbore is measured. A plot representing a wellbore pressure in response to cumulative injection fluid volumes is substantially linear is determined. After determining the plot is linear, a first injection fluid pressure measured in response to flowing the injection fluid deviates from the substantially linear plot by a first variance greater than a threshold variance is determined. A second injection fluid pressure measured in response to flowing the injection fluid deviates from the substantially linear plot by a second variance greater than the threshold variance is determined. In response to the above two determinations, flow of injection fluid into the closed wellbore is stopped.

  • Patent number: 10277248
    Abstract: Systems and method provide for consistent throughput of one or more compression engines. Data received from an input stream is stored in a buffer. Data is read from the buffer and distributed to the compression engines. Latency of the compression engines is monitored. If latency exceeds a threshold, data is read from the buffer and written to an output stream simultaneously with reading of data and inputting it to the compression engines. Data from the input stream may be evaluated for likely compressibility and non-compressible data may be written to the output stream bypassing both the buffer and the compression engines.

  • Patent number: 10260317
    Abstract: A computer system and method of automatically generating a Local Grid Refinement (LGR) gridded model of a gas reservoir. A geologic file includes information identifying the locations of one or more wells according to root grid cells within a volume of the earth to be modeled. User inputs specify the number of hydraulic fractures from each well, and such parameters as the fracture length, etc. User inputs also specify the number of “splits” of the root grid cells containing hydraulic fractures; those root grid cells are then split into finer resolution grid cells of increasing width within the root grid cells containing the fractures. For horizontal wells, user inputs indicate the number of splits of root grid cells containing the lateral portions of the wellbore. Non-orthogonal and complex fractures are processed by a “nested” LGR approach.
