Downhole display

A computer system for displaying a well trajectory, the computer system comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions executable by the processor for:
• receiving a first trajectory information associated with a planned wellbore path;
• receiving a second trajectory information associated with an actual path of a wellbore being drilled;
• responsive to receiving the first trajectory information and the second trajectory information, generating a display on a display device of aa first portion of the planned wellbore path, ii) a first portion of the actual path of the wellbore being drilled, and (iii) a plurality of regions with each of the plurality of regions being associated with a corresponding area of uncertainty based on a difference between the actual path of the wellbore being drilled, wherein:
• the plurality of regions displayed on the display device comprise a first region and a second region;
• the first region comprises a first area of uncertainty;
• the second region comprises a second area of uncertainty;
• and
• the first area of uncertainty is different from than the second area of uncertainty;
• and
• responsive to a user input, adjusting the display on the display device.

A non-transitory computer readable medium comprising program code, which when executed by a processor is configured to cause the processor to:

• receive a first trajectory information associated with a planned wellbore path;
• receive a second trajectory information associated with an actual path of a wellbore being drilled;
• and
• responsive to receiving the first trajectory information and the second trajectory information, generate a display on a display device of aa first portion of the planned wellbore path, (ii) a first portion of the actual path of the wellbore being drilled, and (iii) a plurality of regions with each of the plurality of regions being associated with a level of trajectory error based on a difference between the actual path of the wellbore being drilled and the planned wellbore path, wherein:
• the plurality of regions displayed on the display device comprise a first region and a second region;
• the first region comprises a first level of trajectory error;
• the second region comprises a second level of trajectory error;
• and
• the first level of trajectory error is lower than the second level of trajectory error.
