Enhancing Reservoir Simulation Through Data Visualization and Analysis Software

Oil and gas exploration, and the ever-increasing amount of subsurface data that accompanies exploration, has given rise to the demand for tools with the ability to effectively handle, analyze, and visualize these data in their precise geospatial position. For a long time, reservoir engineers have relied on software from companies such as Landmark (Halliburton), Schlumberger, and CMG for this purpose. In the well planning and asset development process, the main goal of the team has been to create a reservoir simulation model that can accurately perform the following tasks:
  • Depict the structural, petrophysical, and production characteristics within the reservoir.
  • Predict the reservoir performance with multiple iterations and evaluation options.
  • Maximize the recovery with data enhancing the prediction
CoViz® 4D aims to assist oil and gas professionals in the process with its advanced data handling, analysis, and high-resolution modeling capabilities.

Enhancing the Effectiveness of Reservoir Simulation Model

Reservoir simulation deals with the construction of a 3D model that can ideally represent the actual behavior of the reservoir. However, achieving this can be difficult given the dynamic nature of the reservoir. Geologists, geophysicists, drilling and reservoir engineers, and well planners and developers have relied on the static and dynamic reservoir data and their effective integration in order to enhance the accuracy of the simulation model.

Much advanced software, such as CoViz 4D has helped reservoir engineers and geoscientists in the process of using these diverse multi-component data to accurately characterize the reservoir attributes and optimize the model to enhance the reservoir simulation. The improved model can present better production estimates in a fewer number of iterations, providing an economic advantage in the recovery process.

Integrating Diverse Datasets

CoViz 4D makes the combining of diverse static and dynamic data and models easier along with the import and integration of other relevant subsurface information. The static dataset including well logs, seismic surveys, and core data, and dynamic data such as production history, fluid level, pressure, and saturation can be integrated into the data registry, facilitating easy data access for analysis and visualization. The ability to visualize data in a single geospatial volume can help in understanding data interrelationships enhancing the understanding of the reservoir.

Seismic History Matching

In the study of accuracy and consistency, CoViz 4D can ideally compare time-series seismic response against the reservoir simulation model with tools including cross plots and regression analysis. The Sim2Seis module of CoViz 4D also facilitates:

  1. Creation of time-variant petroelastic model using flow model obtained from reservoir simulation
  2. Generation of synthetic seismic volume using the petroelastic model
  3. Qualitative and quantitative comparison of the synthetic seismic volume with the actual seismic input to understand data variations and the changing reservoir conditions

The ability to integrate a wide range of spatial and temporal data, explore correlations, test and compare scenarios can help in creating a refined model that can help in much accurate analysis of reservoir performance.

Leveraging CoViz 4D for Continual Development of Reservoir Simulation Model

Dynamic Graphics,® Inc.’s CoViz 4D is an effective platform for petroleum professionals to gain a detailed understanding of reservoir behavior and potential performance. The capability of the software to collaboratively compare, analyze, and visualize different data and models allow asset teams to easily reduce uncertainty through cross-evaluation of the reservoir simulation model with relevant subsurface data. With the optimized and best version of the reservoir simulation model, it is possible to get much accurate analysis and prediction for asset development and reservoir management.
