Patent ID: 7653563

Claim:
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.
