Visualizing spatio-temporal data on evolving entities or processes requires the definition of a 3D space within which change occurs over time. Understanding the temporal evolution, at varying positions within a defined 3D space, requires robust visualization of any 3D data with the ability to view the data at specific times (4D) as changes occur to the entity or process. Complex 4D visualization and analysis can only be achieved through sophisticated computer solutions which enable flexibility in animating through time regardless of varying times in the required data.

Spatio-temporal problems often require the ability to handle a massive amount of data. These data usually come from multiple sources and include various data formats, 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.

DGI’s CoViz 4D has the unique capability to produce flexible and sophisticated 3D and 4D visualizations of many types of spatio-temporal data. It has the ability to conduct user defined mathematical analyses and extract analytic information from input data. Additionally, CoViz 4D through its data registry and data plugins, has robust data import capability which can make entry of massive datasets possible with minimal duplication and minimal effort.

Data Visualization in the Oil and Gas industry: Accuracy with Spatio-Temporal Data

A comprehensive understanding of the subsurface is needed for geoscientists and engineers to make sound economic decisions in oil and gas projects. Traditionally, the process of analyzing and visualizing spatio-temporal data has relied on 2D maps, spreadsheets, and plots which requires an extensive effort to cross-correlate and interpret disparate data types to discover subtle but economically important characteristics and anomalies in the geoscience and engineering data. Now, with advanced visualization technologies, it is possible to import, integrate and present many types of data as various 3D representations or 3D models along with the corresponding temporal variations for advanced 4D analysis. The correlation and patterns derived through comprehensive modeling can accurately mimic the static and dynamic attributes of a reservoir and, in turn, improve  the accuracy in estimation and planning asset development.

4D Seismic Data Visualization

4D seismic is by its nature spatio-temporal and is one of the oil and gas industry’s most economically successful spatio-temporal technologies. The primary objective of 4D seismic data is to help document, by the acquisition of successive 3D seismic surveys, the production of hydrocarbons from a major reservoir. The variation of seismic attributes throughout the productive life of the reservoir can help determine fluid flow within the reservoir and production efficiency.

Spatio-Temporal Analysis of Oil and Gas Production Data

Oil and gas production data is collected by association with a specific well(s) and recorded on a regular basis. This gives the information a location and a time of occurrence and it is by definition, spatio-temporal. This information is typically recorded as purely digital and its spatial attribute is largely underutilized.
