Method and apparatus and program storage device adapted for visualization of qualitative and quantitative risk assessment based on technical wellbore design and earth properties
First Claim
1. A method of determining and displaying a risk assessment, comprising the steps of:
- receiving a plurality of input data calculation results associated with a wellbore;
comparing each calculation result of said plurality of input data calculation results with each logical expression of a plurality of logical expressions to rank said calculation result; and
calculating a plurality of ranked individual risks extending along a depth of said wellbore in response to the ranking step, each of said plurality of ranked individual risks representing an input data calculation result that has been ranked by said logical expression as having a risk severity selected from a group consisting of a high risk severity, a medium risk severity, and a low risk severity;
generating risk information in response to said plurality of ranked individual risks;
displaying said risk information, the displaying step including displaying said risk information on a risk information display, said risk information display including a simultaneous display of said plurality of ranked individual risks calculated along said depth of said wellbore;
modifying a well design for said wellbore using said plurality of ranked individual risks; and
performing a drilling operation at the wellsite based on the well design.

Abstract
A method is disclosed for determining and displaying risk information in response to a plurality of input data, the input data including a plurality of input data calculation results, comprising the steps of: comparing each calculation result of the plurality of input data calculation results of the input data with each logical expression of a plurality of logical expressions; ranking by the logical expression the calculation result; and generating a plurality of ranked individual risks in response to the ranking step, each of the plurality of ranked individual risks representing an input data calculation result that has been ranked by the logical expression as having either a high risk severity or a medium risk severity or a low risk severity; generating the risk information in response to the plurality of ranked individual risks; and displaying the risk information, the displaying step including displaying the risk information on a risk information display.
