Streamline Analysis

Streamline simulations can be used for dynamic analysis of the reservoir, for validation and ranking of reservoir modeling scenarios, and for quality control of property upscaling. Due to its fast algorithms, streamline simulations work for large models where conventional simulation methods struggle to deal with the large number of grid cells. With RMS™, dynamic simulations can be performed with both geo models and flow models. 

RMS Streamline Analysis Benefits 

  • Simple and fast, streamline analysis can be integrated into all modeling workflows 
  • Designed to be easily accessible and usable for both geologists and reservoir engineers 
  • Complementary to conventional reservoir simulation, but can also be used for large geological models 

RMS Streamline Analysis Features

  • Analysis can be based on streamline visualization, 3D report parameters, drainage functions, and breakthrough times 
  • Can be used to visualize main flow patterns in the model, to rank geo models, design optimal well locations, or validate upscaling results 
  • In addition to the single-phase option, contains a Buckley-Leverett model for two-phase flow 


Dynamic Analysis for Reservoir Modeling

RMS Streamline Analysis provides fast and early assessment of reservoir flow characteristics at various scales of the reservoir model, even on multi-million cell geological models. With a user-friendly interface, the RMS Streamline Analysis tool can be used by both geoscientists and reservoir engineers to quickly validate geological models and/or upscaled simulation models. Integration with RMS and its workflow tools allows easy screening and ranking of multiple realizations and/or scenarios. 

Ranking Geological Scenarios 

Uncertainties within the reservoir may require modeling of multiple geological scenarios in order to quantify their impact on field development planning. With its ability to handle large number of cells, streamlines are an ideal tool for the dynamic ranking of multiple scenarios.   

Validation of Upscaling Results 

Conventional flow simulation grids are often much coarser than fine-scale geological grids. Upscaling of reservoir properties is therefore often employed to reduce the number of cells while attempting to capture the effects of fine-scale heterogeneity. RMS Streamline Analysis provides a quick way to analyze the impact of upscaling on fine-scale reservoir heterogeneity, helping to ensure the accuracy of the results. This is done by comparing the streamline results for both the original geological and upscaled simulation models.  

Gridding Design 

Streamlines can be used to help optimize simulation grid design, ensuring that the level of coarsening and grid orientation captures the fine-scale heterogeneity. Multiple grids can be built and then compared using streamlines, a process which can be automated through the workflow manager in RMS.  

Well Location and Optimization

Streamline simulations can provide a fast and early assessment of the well locations. The sensitivity analysis can be performed by ranking streamline simulations with respect to sand connectivity, drainage volume, breakthrough times and pressure in the wells.
