One seismic cube out of a time-lapse series shown with the velocity cube, different geologic models, reservoir simulation grid, production data, and well paths, completions and logs. Putting all this 3D and 4D data into a single environment provides a coherent history of a reservoir leading to better insights than viewed in different groups.
Visualization of subsurface data associated with hydrocarbon assets has evolved from the acquisition of millions of seismic data points (1D) that create two-dimensional (2D) images showing subsurface geology, to three-dimensional (3D) seismic data visualizations. The level of detail continually improves with more precise data acquisition capabilities, ever-greater data volumes, and sophisticated processing algorithms.
The Value of 4D Seismic Data Visualization and Analysis
Visualizing Time-Variant Seismic Data
Understanding the changing response of a reservoir over time is critical for making development decisions that optimize production. Quantitative visualization of evolving time-variant seismic data gives asset teams the ability to:
- visualize well trajectories, perforations, treatment curves, and induced fracture locations as new well events and seismic data are added
- analyze microseismic event geometry over time, including geological, petrophysical, and reservoir data, captured during hydraulic fracturing to present the microseismic data in their true geologic context
- compare the 4D seismic response with the dynamic model and the well/production data for better history matches and a more accurate understanding of the 4D seismic response
- understand the evolution of fluid and gas movement and saturations within the reservoir
- calculate displacement, overburden strain, and seismic time-shifts due to reservoir compaction to prevent formation damage that could degrade the ability to economically extract recoverable hydrocarbons
- monitor injection water replacing oil to confirm the effective performance of the water injection along the completed intervals
