Abstract
A system can generate and output boundary lines for controlling a drilling operation. The system can receive data, including an offset well surveys, measuring instrument information, and a well casing diameter, about offset wells in a subterranean formation. The system can determine reference well values. The system can generate boundary lines for the offset wells based on the received data and the calculated reference well values. The system can adjust the boundary lines, and can output the adjusted boundary lines for controlling a drilling operation.
Claims20
A system comprising:
- a processor;
- and
- a non-transitory computer-readable medium comprising instructions that are executable by the processor to cause the processor to perform operations comprising:
- receiving data including a plurality of offset well surveys, measuring instrument information, and a well casing diameter, about a plurality of offset wells in a subterranean formation;
- determining, for each interval in a plurality of intervals along a trajectory of a reference well, reference well values;
- generating a plurality of boundary lines for the plurality of offset wells based on the received data and the determined reference well values, the plurality of boundary lines usable to adjust a trajectory of a drilling operation for forming a wellbore within the plurality of boundary lines;
- adjusting the plurality of boundary lines by:
- determining a tool-face angle associated with a first subset of the plurality of boundary lines for a particular depth interval;
- and
- at a previous, adjacent depth interval that includes a second subset of boundary lines, adjusting the second subset of boundary lines by a predetermined percentage using the tool-face angle associated with the first subset of the plurality of boundary lines;
- and
- controlling a drilling operation using the adjusted plurality of boundary lines.
