Rock Flow Dynamics releases tNavigator 21.2

Rock Flow Dynamics released the second update in 2021 of the tNavigator software package. Version 21.2 is now available to users. Updates and improvements affected the simulator kernel, AHM and Uncertainty module, Geology and Model Designer, PVT Designer, Well and Network Designer.

The key new features are:

  1. In simulation kernel:
    • The basic support of new formats — NE and IN — has been introduced in Simulator and Model Designer.
    • For isothermal models, the RP hysteresis option can now be used together with the miscible displacement option (MISCIBLE, for compositional models), salt dependent RP (LOWSALT), and the surfactant option (SURFACT).
    • A new full-GPU calculation mode has been added with lowered GPU memory requirements (the option GPU_MODE=5).
    • A new linear system scaling algorithm has been added which allows a decrease in the number of linear iterations (TNAVCTRL SCALE_MATRIX 2).
  2. In graphical interface:
    • Graphs of rates for lumped connections may be visualized
  3. In the Assisted History Matching and Uncertainty module:
    • An easy way to generate an initial population of porosity and permeability properties for the Ensemble algorithm is now supported; a set of variables to launch the algorithm may now be created as well.
    • Matching to RST data (test data of saturation along the wellbore) and PLT data is now supported.
  4. In Geology and Model Designers:
    • Creation and storing of several trajectory versions for one well with an option to choose between them and set the default one is now available.
    • A library of ready-made scripts has been added to the Workflow window.
    • Quick Workflow calculation runs on the cluster are now supported, as well as the transfer of the results of the project Workflow calculation from the cluster to the local computer.
    • Several types of objects can now be displayed in the Crossplot tab. This feature helps compare created properties with the source data or several implementations of a property with the source data during quality control.
  5. In Geology Designer:
    • Different seismic surveys can be tied together.
    • Geosteering data may be received in real-time through the WITSML protocol.
  6. In Model Designer:
    • A calculator has been introduced that can be used to compute a conductivity map. The custom formula of a conductivity calculation may contain different grid properties, other calculation results of Fracture Simulator, etc.
    • Calculated Drainage Tables and Graphs can be displayed in the Graphs tab.
  7. In Well Designer:
    • Logs and markers may be visualized in the Well construction tab.
  8. In Network Designer:
    • The corrosion of pipe material may now be modeled using the deWaard (1995) model.
  9. In PVT Designer:
    • The CO2 solubility in water by Henry’s Law for the CCE experiment has been implemented.
