15 09 | 23

Rock Flow Dynamics (RFD) is pleased to announce the release of the latest version of our flagship product, tNavigator. Version 23.3 is now available to users.

Key new features in 23.3

In the Simulator kernel:

  • It is now possible to model dimethyl ether (a solvent partially miscible with water) using the CPA-SRK equation of state.
  • It is now possible to use the GERG-2008 equation of state together with the option of multiple components’ solubility in water and the CO2 solubility option.
  • Geomechanical modeling is supported for compositional and thermal models whose primary variable is temperature.

In Geology Designer and Model Designer:

  • A version control system has been implemented in Geology Designer and Model Designer: Teamwork. This system is designed for several users to work on one project.
  • It is now possible to visualize the grid of geographic coordinates in the 2D tab.
  • An option to display well test info in a Cross-Section tab has been implemented.
  • An option to display 3D grids and their properties in Simbox View mode has been added.

In Geology Designer:

  • An option to work with several sets of markers for the same horizon has been implemented.
  • A new interpolation method has been added: Plurigaussian simulation.
  • A new object has been added: Interval Logs. This object allows work with interval core measurements, well log interpretation results, etc. The main feature of the object is storing information about the sampling interval, i.e., the MD (Measured Depth) of the top and bottom of each sample.

In Seismic:

  • A calculation for seismic horizon autotracking by surveys 2D has been added.
  • It is now possible to take into account seismic faults during autotracking of seismic horizons by survey 3D.
  • It is now possible to thin out the correlation of a seismic horizon with the given step along inlines and crosslines.
  • It is now possible to determine the optimal parameters of frequency channels automatically during Spectral Decomposition calculation.
  • When calculating misties between seismic surveys, it is now possible to create a point set with numerical attributes in which the correction values will be stored.
  • During mistie calculation between 2D seismic surveys, it is now possible to enter variable vertical corrections along a 2D line.

In Model Designer:

  • In the well rules interface, the Apply Script rule can now contain other rules, which then can be accessed from the code.

In Fracture Simulator:

  • For measurement points that are specified in well settings, new graphs have been added: proppant concentration, slurry density, frictional pressure loss, etc.

In PVT Designer:

  • It is now possible to model dimethyl ether (a solvent partially miscible with water) using the CPA-SRK equation of state.
  • It is now possible to set temperature functions for the density shift model.
  • It is now possible to calculate phase properties as temperature-dependent functions in PVT Calculator.

In Network Designer and Well Designer:

  • It is now possible to include the surface equipment specified in a Well Designer project (flowlines, chokes) in network calculations.

In Network Designer:

  • To simulate Heat Exchanger objects, enthalpy calculation for custom (non-library) components of fluid composition (specified in PVT Designer) can now be performed using the equation of state.

In Network Designer:

  • The calculation of hydrate plugs in pipes is now supported. It is now possible to calculate and create a graph of the percentage of the pipe filled with hydrates.
  • A new type of optimization based on the objective function is now supported for integrated and Standalone models for Constraints and Master Constraints objects.
  • A new tab titled “Wells” has been added to visualize graphs of calculated parameters along well trajectories.

In Well Designer:

  • A new well construction object—Labyrinth Inflow Control Device (LICD)—has been added.

In RP Designer:

  • New options to model the effect of miscible displacement and low-salt water injection on the relative permeability and capillary pressure curves are now available.

In Material Balance Analyzer:

  • New graphical analysis methods have been added. For Gas Reservoirs: P/Z over-pressured, Havlena–Odeh over-pressured, and Roach. For Oil Reservoirs: Havlena–Odeh, Havlena–Odeh water-drive, F – We vs Et, and (F – We)/(Eo + Efw) vs Eg/(Eo + Efw).New tabs have been added: Surface Equipment, Nodal Analysis, and Parametric Analysis.

In Dispatcher and License Server:

  • A remote configurator for dispatchers is now available.
  • It is now possible to open another project of Model/Geology/PVT/Network/Well Designer instead of the current project with guaranteed hold of the license (that is, making sure the license will not be snatched by another user).

In License Server and Installer:

  • The license statistics report now contains graphical information.
  • In the tNavigator installer for Linux (like in Windows earlier), two profiles with predefined choice of components have been added: For workstation and For cluster.
