|For Standard||WITSML v2.0|
Figure 7.6.1-1 is the UML diagram of the risk data object. Certain elements are required for the risk object to be both valid and of practical use. Other elements represent a “best practice” that is helpful for the risk to be properly interpreted. The risk data object:
- Must reference its parent wellbore.
- Must include these elements:
- Type: the type of risk, e.g. gas kick.
- Category: the category of risk, e.g. hydraulics or equipment failure”
- DTimStart and DTimEnd: if applicable, date and time that the risk started and ended.
- MdHoleStart and MdHoleEnd: if applicable, the measured depth at the start and end of the risk.
- TvdHoleStart and TvdHoldEnd: if the risk is associated with a depth range and MdHoleStart/MdHoleEnd have not been provided, then these should be provided.
- SeverityLevel: severity level of the risk, values 1 through 5, with 1 being the lowest.
- ProbabilityLevel: probability level of the risk, values 1 through 5, with 1 being the lowest.
- Summary: a summary description of the risk. If needed, provide more information in Details.
- Contingency: the plan of action if the risk materializes.
- Mitigation: plan of action to ensure the risk does not materialize.
