Abstract
A system and method for providing information regarding the tortuosity of a wellbore path is provided. The method includes receiving data from a plurality of survey stations of a wellbore survey. The method further includes defining a plurality of reference lines for the wellbore path. The method further includes determining a plurality of displacements of the wellbore path from the plurality of reference lines.
Claims20
A method, comprising:
- receiving survey data corresponding to a plurality of survey stations of a wellbore survey of a wellbore path;
- determining a plurality of curved reference lines for the wellbore path based on the received survey data;
- and determining a plurality of displacements of the wellbore path from the plurality of reference lines.
A method, comprising:
- receiving survey data corresponding to a plurality of survey stations of a wellbore survey of a wellbore path;
- and determining tortuosity for the wellbore path within a plurality of analysis windows based on the received survey data and based on a maximum device length (Lmax) for a respective analysis window, wherein the Lmax comprises a maximum allowed length of a model tubular device that can be placed at, or passed through, a portion of a wellbore defined by the respective analysis window.
A method, comprising:
- receiving survey data corresponding to a plurality of survey stations of a wellbore survey of a wellbore path;
- and determining tortuosity for the wellbore path within a plurality of analysis windows based on the received survey data and based on an effective inner diameter (Deff) for a respective analysis window, wherein the Deff comprises a maximum width of an outer periphery of a model device with a specified length that can be placed at, or passed through, a portion of a wellbore defined by the respective analysis window and configured to withstand a specified amount of bending.
