UPPER SAND, TIME 2003.

Integrating time-lapse seismic, reservoir simulation, well completion and production data in the same geo-located space can greatly enhance the understanding of reservoir conditions and performance. Data used by permission of the owner.

Reservoir characterization can be challenging. Oil and gas exploration and production companies are increasingly looking for technologies with scope to enhance their data interpretation and characterization abilities of conventional and unconventional reservoirs. Accurate integration of vast amounts of data is crucial for proper reservoir characterization. The integrated data allows teams to optimize their process during the development, design, and recovery phase. The ability to visualize a wide array of integrated data further enhances this ability for cost-efficient production design. 

Data for Enhancing Reservoir Characterization

An efficient reservoir characterization provides a detailed analysis of the subsurface in the potential hydrocarbon production field. The exploration phase seeks to minimize the uncertainty related to the reservoir properties through the collection of a wide range of subsurface data. During the drilling of an initial well, various techniques including seismic surveys and well logging, provide essential data on geological, lithological, and petrophysical properties of the reservoir. The subsequent analysis of this data may include information regarding:

  • Hydrocarbon and water saturation
  • Resistivity
  • Subsurface lithology
  • Porosity and permeability
  • Rock density
  • Temperature and pressure

These properties identified through core data, open hole data, geological models, and seismic interpretation, help in the initial characterization of the reservoir. This is key to well planning, placement, and completion.

Data collected and used for the initial and subsequent characterization of an asset’s reservoir are complex, geospatially oriented, geoscientific, and engineering data and models. Efficient analysis of these differing data sets is challenging due to disparate data formats and interpretation software used to create each characterization model.

Visualizing the Data for Efficient Interpretation

The challenges of developing correlations from diverse data formats can be reduced with the help of software like CoViz 4D. With effective data integration technology, it is easier to combine and interpret the different data formats for developing subsurface geological correlations and analyzing reservoir characteristics. Reservoir engineers can refer to this analysis to make an informed decision on well placement, completions, and production strategies.

Enhanced reservoir characterization can be simplified with the addition of 3D modeling and visualization. The characterization process can benefit from data visualization in the following ways:

  • Temporal and geospatial data can be integrated and cross-correlated.
  • The early reservoir characterization and interpretation can be re-evaluated with the addition of new data. The re-evaluated data can be used for developing an accurate and enhanced reservoir model and make plans for further field development.
  • Integrate differing data to determine comprehensive characteristics of reservoirs across the oil field.
  • Identify data inaccuracies through visualization and effective collaboration across teams.

CoViz 4D for Enhanced Reservoir Characterization

Dynamic Graphics Inc.’s CoViz 4D is particularly well suited for the visualization of relevant asset data and the creation of successive re-evaluations of a reservoir’s characterization. The software provides a unique single platform for integrating disparate datasets for identifying the nature of the reservoir and its changes over time. With the integration and visualization of the new and existing data, re-evaluation can be done which can be especially beneficial in understanding the reason for underperformance. This also allows teams to develop ways to reduce risk and improve the future production process.

CoViz 4D, a data visualization software from Dynamic Graphics, Inc., gives oil and gas producers the ability to easily access, integrate, and visualize all the relevant data for enhanced reservoir characterization and 3D modeling. To learn more about CoViz 4D contact our team.
