CoViz 4D: A Guide to Oil and Gas Risk Management

The many economical, geological, and operational aspects make the oil and gas industry a volatile and risk-prone sector. From planning and decision-making to actual implementation, there are many variables that increase the opens in a new windowlevel of uncertainty for the asset team to manage.

Visualizing drilling target uncertainty in the geologic context can assist in understanding drilling risk.
The many geological, and operational aspects make the oil and gas industry a volatile and risk-prone sector. From planning and decision-making to actual production, there are many variables that increase the level of uncertainty for the asset team to manage.
Oil and gas risk management attempts to minimize this uncertainty to ensure productive and cost-efficient operations. One of the ways this can be achieved is through the complete and accurate input and analysis of related information. This can be achieved with technology that can ideally handle, visualize, and analyze multi-disciplinary data. Software platforms such as CoViz® 4D can accurately examine the wide range of data to make an informed and reliable decision through each phase of a hydrocarbon asset development project.

Enhancing the Reliability of Risk Assessment

In the oil and gas industry, risk is inherent during the exploration, planning, development, and recovery phases of a project. . The dynamic nature of the reservoir and varying subsurface geology  make the decision-making process difficult due to incompletely defined geologic and engineering complexities. The uncertainties can be related to:
  • Geologic variability within the producing reservoir
  • Estimation of the hydrocarbon volume in place using depth-converted horizons
  • Complex subsurface geology comprising the reservoir’s trap.
  • Wellbore positioning and depth assessment
  • Inter-well spacing
  • Well trajectory design and optimization

The qualitative and quantitative analysis of these uncertainties is required to gain a better insight into the subsurface environment. For geologists, geophysicists, reservoir and drilling engineers, and project managers, CoViz 4D can prove to be an ideal oil and gas risk management tool.

Using Data to Visualize Uncertainty

As shown above, viewing subsurface data in two domains, time and depth, at the same time can greatly assist in understanding risk factors related to depth conversion. Data used by permission of owner.
A key element of  oil and gas risk management is access to as much related technical data as possible—which can be available from seismic surveys, geological studies, well logs, and production performance. These data from a wide range of disciplines allow engineers and geoscientists the ability to analyze the interrelationship between different spatial and temporal subsurface conditions, features and  attributes in a wide range of scenarios. The ability to visualize these uncertainties in a 3D/4D environment further supports the team in making a well-informed risk weighted decision at every phase of asset development.
CoViz 4D provides an interactive platform where a wide range of data can be imported from various sources and analyzed collaboratively. This data can be used to enhance the development of a 3D reservoir simulation model which can closely  reflect the actual behavior and characteristics of the reservoir. The visual analysis can provide a more comprehensive insight into the subsurface engineering conditions and their related geological complexities. The data can be cross-correlated and maps overlapped to validate the result from the individual analysis helping to  reduce uncertainty and increase reliability of economic predictions for the asset.

For uncertainty and risk analysis, CoViz 4D enables:

  • Visual analysis of geological, geophysical, petrophysical and engineering subsurface characteristics
  • Enhanced identification of geologic complexities  (faults, fractures, lithology and stratigraphy) that may hinder drilling and recovery
  • Spatial definition of  producing and depleted zones for ideal well path planning
  • Design of the trajectory of a well to avoid collision and improve target accuracy
