I. Basic Software Introduction

tNavigator-setup-Win-64-25.1 is the installation package for the 25.1 version of the reservoir numerical simulation software, exclusively developed by RFD for the Windows 64-bit platform.

• ‌Core Positioning‌: A new-generation high-efficiency reservoir numerical simulation system that supports reservoir model operations with 10 million to 1 billion grid nodes, eliminating the need to upscale fine geological models.

• ‌Hardware Adaptation‌: It only supports 64-bit Windows operating systems, and can fully leverage multi-core CPU and GPU resources to achieve hybrid parallel acceleration,

• greatly improving the efficiency of reservoir simulation operations.

• ‌Industry Applications‌: It has been widely adopted by major oil companies worldwide, serving as the core component of the Coresine integrated solution, and is compatible with various development scenarios

• such as conventional oil and gas, tight oil, and CO₂ storage.

II. Core Feature Highlights

• ‌Full Parallel Computing Capability‌: It supports full-GPU parallel mode and cluster MPI parallel algorithms, realizing maximum parallel computing on multi-core CPU+GPU workstations with high memory utilization

• and balanced load distribution.

• ‌Multi-scenario Simulation Support‌: It can simulate complex development processes such as fractures of any shape, refracturing, CO₂ huff and puff, and fracturing-flooding development, meeting the special simulation

• requirements of unconventional oil and gas development.

• ‌Real-time Visual Monitoring‌: It can output 2D/3D streamline results in real time during the operation, without the need for separate streamline simulation. It can directly generate the fluid distribution table of injection-production wel

• l groups to quantify the injection-production relationship.

• ‌Intelligent Optimization Module‌: It is built with intelligent optimization algorithms including Monte Carlo and Particle Swarm Optimization, supports custom objective functions, and can automatically complete the

• optimization of history matching parameters, well pattern schemes and production systems.

III. Basic Installation and Usage Instructions

• ‌Pre-installation Preparation‌: Confirm that your Windows system is a 64-bit version, the hardware configuration meets the minimum operation requirements of version 25.1, and obtain the software license file in advance.

• ‌Installation Operation Process‌: Double-click to run the tNavigator-setup-Win-64-25.1 installer, select the installation path according to the wizard prompts, complete the component deployment, import the license file,

• and finish activation to launch the software.

• ‌Basic Project Operations‌: After creating a new project, import the fine geological model, set basic parameters such as PVT properties, fluid components, well trajectories, and configure the development mode

• (conventional development, CO₂ huff and puff, fracturing-flooding, etc.) as needed.

• ‌Simulation Operation Settings‌: Allocate parallel computing resources, set the simulation time step and output frequency, start the operation, and view the simulation progress and intermediate results in real time to adjust parameters

• timely.

• ‌Post-processing of Results‌: After the operation is completed, directly export outputs such as production data, pressure field distribution, and streamline distribution, and generate injection-production optimization schemes

• and development effect evaluation reports.
