tNavigator 22.2


tNavigator is a powerful software for dynamic simulation of oil and gas tanks. This program is a collective effort of RFD researchers and development team. It can be installed on personal systems, laptops, servers and even HPC clusters. The program is written in C ++ and uses the latest parallel processing technologies and hardware accelerators. The processing speed and performance of this program is commensurate with the hardware capacity of the host system.

Definitely, if you run the program on cluster systems with multiple processing cores, you will see a significant increase in the speed of simulation and processing operations. No technology has been spared to maximize the processing speed of complex models, NUMA, Hyperthreading, MPI / SMP hybrid computing and have been used well where necessary. All of these technologies have been used to ensure that the program serves the professionals with maximum efficiency and outperforms other competitors by a significant margin.

In the product introduction page, interactive simulation is one of the main features of this product. In fact, unlike other simulation tools, this product not only allows monitoring at the moment of reservoir simulation operations, but also allows users to change their desires and parameters during the simulation with a few mouse clicks. See results. This will facilitate the simulation and parametric study of oil and gas reservoirs and will definitely save a lot of time. We recommend that you use tNavigator as one of the best tools in this field if you are involved in reservoir simulation processes in the field of oil and gas engineering or even need research for this final dissertation.

The key new features in tNavigator 22.2 are:

• In the Simulator kernel:
◦ For compositional models in E3 format, the option of rock wettability dependence
on the adsorbed solid concentration is now supported.
◦ For thermal models in E3 format, calculation of the heat transfer between a segment
of a multisegment well and a grid block (through the corresponding perforation
interval), between a segment and another segment or a surface with a constant
temperature is now supported.
◦ For compositional models, the simulation of acid-base reactions by setting equilibrium
constants in the water phase is now supported.
◦ The option of blockwise specification of the power parameter for the Corey/LET
RP correlations is now supported.
◦ It is now possible to modify endpoint scaling properties in blocks with fractures.
◦ Results upscaling for further export in binary format (GRID, EGRID, INIT,
UNRST, and UNSMRY files) is now available. Grid scaling is performed in accordance
with the algorithm of the COARSEN keyword.

• In the Simulator GUI:

Production calculation and display of results by branches of
multilateral wells are now supported.

• In the Assisted History Matching and Uncertainty module: It is now possible to display
an initial distribution of variables and quantiles on a histogram.

• In Geology and Model Designers:
◦ The following new attributes have been added for series objects in the Crossplot
tab: symbol size, symbol type and transparency.

• In Geology Designer:
◦ A 3D-Grid may be created based on a source one, which will be cut by the specified
faults (the Create Grid by Faults Cutting calculation).
◦ Object visualization may be managed in the Object tree via tags in the Stratigraphic
◦ It is now possible to calculate areas of adjacency for various discrete classes by
grid faults (the Calculate Areas of Adjacency calculation).
◦ The amplitude between fault lines may be set using a pre-created fault attribute
(Correct Fault Lines Amplitude by Attribute calculation).

• In Model Designer:

◦ The interface to set the parameters of chemical reactions is now available.
◦ A multicomponent model can now be used to calculate the flow when injecting
fluids and proppants of several types.
◦ It is now possible to calculate simultaneous propagation of fractures from several
perforations located at a small distance from one another in a specified wellbore
◦ The liquid and proppant flows, the liquid composition and the well diameter are
now used to calculate the pressure losses in injection.

• In Well Designer:

It is now possible to calculate IPR correlation parameters as a function
of bottom hole and reservoir pressure.

 In Network Designer:
◦ It is now possible to set temperature zones for pipes.
◦ A new Valve object has been added to allow/prohibit fluid backflow.
◦ It is now possible to set a maximum flow limitation for an automatic choke. To
calculate the diameter of the automatic choke, simultaneous setting of a flow limitation
and a control type for inlet/outlet pressure is now supported.

 In PVT Designer:
◦ An option for slow outflowing (bleeding) at the last stage of a DLE experiment is
now available.
◦ It is now possible to create and import a custom database of fluid components.
