Method and apparatus and program storage device adapted for automatic qualitative and quantitative risk assessment based on technical wellbore design and earth properties
First Claim
1. A program storage device readable by a machine tangibly embodying a program of instructions executable by the machine to perform method steps for determining and displaying risk information based on a technical wellbore design and Earth properties, the method steps comprising:
- generating a drillstring design for a wellbore in each hole section of the wellbore in response to a required wellbore geometry and a required wellbore trajectory of the wellbore;
receiving input data, the input data including input data calculation results associated with the wellbore;
comparing each calculation result of the input data calculation results with a logical expression;
ranking by the logical expression each of the input data calculation results, and generating ranked risk values extending along a depth of the wellbore in response thereto, each of the ranked risk values representing an input data calculation result that has been ranked by the logical expression as having a risk selected from the group of a high risk severity, a medium risk severity, and a low risk severity;
generating risk information in response to the ranked risk values, the risk information comprising a ranked risk category, a ranked subcategory risk and a plurality of ranked individual risks; and
displaying the risk information, said risk information display including a simultaneous display of said risk information along said depth of said wellbore.

Abstract
A Software System, known as an Automatic Well Planning Risk Assessment Software System, is adapted to determine and display risk information in response to a plurality of input data by: receiving the plurality of input data, the input data including a plurality of input data calculation results; comparing each calculation result of the plurality of input data calculation results with each logical expression of a plurality of logical expressions; ranking by the logical expression the calculation result; and generating a plurality of ranked risk values in response thereto, each of the plurality of ranked risk values representing an input data calculation result that has been ranked by the logical expression as either a high risk or a medium risk or a low risk; generating the risk information in response to the plurality of ranked risk values; and displaying the risk information.
