Visualizing Big Data: Oil and Gas

To derive a robust analysis, industries require a data platform with capabilities to easily handle this big data. Traditionally, geoscientists and engineers have been using software products from Schlumberger, Landmark Graphics, Paradigm, and ESRI for analyzing and visualizing big data. However, most of these products are discipline-specific which hinders easy data accessibility and collaboration. The solution: CoViz 4D from Dynamic Graphics, Inc.

Reservoir simulation combined with 4D seismic and a wide array of geological and production data all brought together in a collaborative geospatial view. Qualitative and quantitative analysis can be done with all data types. Data used with permission of owner.

CoViz 4D and its modules provide a collaborative geospatial environment where all the data can be brought together, analyzed, and interrogated through qualitative and quantitative analysis to develop a better understanding of the reservoir.

Role of Big Data in Oilfield Evaluation

Efficient decision-making requires a huge data volume that can accurately evaluate the geological features, seismic attributes, production performance, and recovery potential of the reservoir. CoViz 4D provides the ability to import and integrate these data in a single platform where geoscientists and engineers can efficiently collaborate to make the most cost-effective decision.

An important step in this process is the 3D visualization of data. CoViz 4D can combine a wide range of geological and petrophysical data and models to create a 3D representation that can accurately mimic the attributes of the oilfield. Asset teams can utilize this model to visually analyze the complexity and dynamics within the reservoir and understand data correlations. In new or mature oilfields, having a detailed insight into the attributes and their subsequent effects on the performance of the reservoir allows petroleum professionals to make efficient production and design planning while recognizing the economic potential of the project.

Reservoir Monitoring and Production Optimization with Data Visualization

Various temporal and spatial data contribute to the in-depth understanding of reservoir characteristics and performance. Spatio-temporal issues often require the ability to handle a massive amount of data. These data usually include a wide range of incompatibly formatted information which adds to the complexity of data handling and analysis. To efficiently handle and make the best use of this data, it is beneficial to have a software package that has the capabilities of incorporating, integrating, and cross-correlating data from any source or format.
The various features of CoViz 4D including time-step arithmetic analysis, back-interpolation, property averages, and cross-plotting, enables teams to monitor changes and come up with optimization and mitigation plans to enhance the production.

CoViz 4D: Leveraging Software Features to Derive a Comprehensive Solution

Having the ability to quickly load data while drilling or combining well plans with data from actuals help drillers anticipate any potential hazards.

CoViz 4D is ideal for petroleum professionals for importing, integrating, and visualizing big data in a single geospatial environment. A large data volume ensures the development of a highly detailed reservoir simulation model that accurately represents the actual reservoir. Reservoir and drilling engineers, well planners, geologists, and geophysicists can monitor and evaluate the subsurface variations, development in drilling activities, and production performance using the quantitative and qualitative analysis process for improved risk analysis, production optimization, and reservoir management. In doing so, the following features of CoViz 4D play a crucial role:

Real-Time Data Visualization

CoViz 4D can incorporate and display in a 3D model, a wide range of well log data including temperature, pressure, gamma-ray, vibration shock, and rate of penetration to visualize the wellbore at its actual geospatial location within a big data co-visualization environment. With real-time data visualization and analysis, the drilling progress can be monitored and optimized while analyzing the effect of inter-relationship between these various wellbore data. Engineers can avoid potential well collisions and hazards such as over-pressurized zones in drilling by providing safer well deviation options.

Seismic History Matching and Simulation Model Updates

The powerful 4D visualization capability of CoViz 4D supports seismic history matching. By cross-correlating 4D seismic data with the reservoir models and additional relevant datasets, engineers can easily track the fluid migration and production within the reservoir. The provision for synthetic seismic volume enables efficient comparison of models which fosters simulation model updates to ensure uncertainty and discrepancy minimization.

Microseismic Event Analysis

The visualization above illustrates the 3D/4D spatiotemporal integration of geologic structure, fracture stage events, microseismic events, wellbore trajectories, and well logs.

CoViz 4D can easily incorporate microseismic data into a 3D model which enables the visualization of frac status and its efficiency. Users can incorporate a wide range of relevant drilling, geological, and petrophysical data including seismic reflections, acoustic logs, perforations, receiver location, and well trajectories to provide more context to frac. CoViz 4D enables visualization and analysis of these microseismic event data which provides engineers and geoscientists with detailed information on reservoir conditions. This analysis can then be utilized for better well planning and drilling practices for developing safe and optimum recovery strategies.

Through a detailed understanding of the oilfield by visualizing big data, it is possible for asset teams to identify historical and existing field conditions, identify missed opportunities, monitor progress, and determine the ideal recovery options with fewer iterations. The accuracy in planning and design enables avoidance of potential risks, maximization of recovery, and thus, increased returns on investment.
