Well Performance Comparison: The Benefits of Integrated Data Visualization & Analysis

Modern seismic, drilling, and production technologies allow petroleum engineers to generate or acquire substantial volumes of data that characterize well performance—from initial exploration up to yesterday’s production metrics. These data can provide valuable insight when reservoir engineers are considering wells to be drilled into offset prospects or wells drilled to extend an existing producing reservoir.

Mitigating Common Risks in Oil and Gas Production

While there’s no way to completely eliminate mishaps and failures that can create potential risks in oil and gas production, operators can implement key monitoring measures that help them find precarious aberrations sooner rather than later.

Residual Analysis of 4D Reservoir Simulation Grids

Predicting reservoir behavior is crucial for avoiding many challenges in the development of a hydrocarbon asset. A reservoir simulation grid is one approach that geoscientists and reservoir engineers take to analyze reservoir models which provide a better understanding of subsurface conditions. Paired with 4D seismic, reservoir simulation grids can yield a standard way of locating subsurface anomalies and generating a 4D understanding of reservoir behavior to make more informed decisions for efficient asset production. With software that allows for integrated quantitative visualization, users can compare data and models and visually analyze the area of interest to make accurate predictions, reduce uncertainty, and increase cost-effectiveness.

An Integrated Approach to Mature Field Production Optimization

Among the many challenges of managing a mature oil field is the need to obtain an accurate understanding of its remaining recovery potential. Greater accuracy in assessing characteristics that influence recovery—geologic variability changes in fluid saturation, water cut, microseismic events, location and viability of aging infrastructure—enables asset teams to make better decisions regarding mature field production optimization.

Predictive Analytics in the Oil and Gas Industry Aids in Refining Estimated Ultimate Recovery Analysis

Predictive analytics in the oil and gas industry is a vital tool that allows analysts to assess the full composition of recoverable reserves. Without a good understanding of the field, analysts can miss lucrative reserve locations and overlook potential hazards that could hamper operations.

Underground Infrastructure Visualization Through Dataset Integration

Developing and monitoring an underground infrastructure can be a challenging task due to the lack of ability to constantly observe below the surface. Determining the ideal infrastructure location, work zones, networks, and grids can be simplified through the visualization of the associated underground data.
