Abstract
An operating planning system may receive survey data for the wellbore. An operating planning system may, using the survey data, calculating deviations from a planned trajectory of the wellbore. An operating planning system may apply a physical model to the deviations to identify forces on a downhole tool. An operating planning system may, based on the deviations and the forces, generating an operational plan to perform the operation.
Claims20
A method for planning an operation at a wellbore, the method comprising:
- receiving survey data for the wellbore;
- using the survey data, calculating deviations from a planned trajectory of the wellbore;
- applying a physical model to the deviations to identify forces on a downhole tool;
- and
- based on the deviations and the forces, generating an operational plan to perform the operation.
A method, comprising:
- receiving survey data for a wellbore, the survey data having a resolution of less than one stand;
- using the survey data, generating a representation of the wellbore at the resolution of the survey data;
- applying a physical model to the representation of the wellbore to generate a risk assessment for a plurality of downhole tools to perform a downhole operation;
- based on the risk assessment, selecting one of the plurality of downhole tools to perform the downhole operation;
- and
- using the representation and the risk assessment, generating an operational plan to perform the downhole operation with the one of the plurality of downhole tools.
A method, comprising:
- while drilling a wellbore, collecting survey data with a survey frequency of less than one stand;
- using the survey data, calculating deviations from a planned trajectory of the wellbore;
- using the deviations, generating a representation of the wellbore;
- based on the representation of the wellbore, selecting a downhole tool to perform a downhole operation;
- and
- based on the representation of the wellbore and the downhole tool, generating an operational plan to perform the downhole operation.
