Rotational wellbore ranging

A system comprising:

• processing circuitry;
• and
• a non-transitory computer-readable medium storing instructions executable by the processing circuitry to perform operations comprising:
• in a first wellbore in which a wellbore component having an axis of rotation is disposed, moving a wellbore ranging sensor disposed on a circumferential area surrounding the axis of rotation to a plurality of distinct sensing positions on the circumferential area;
• at each sensing position of the wellbore ranging sensor on the circumferential area, measuring a magnetic field from a second wellbore that is apart from the first wellbore resulting in a plurality of magnetic field measurements at the plurality of distinct sensing positions;
• and
• providing the plurality of magnetic field measurements to determine a position of the first wellbore relative to the second wellbore using at least a subset of the plurality of magnetic field measurements.

A system comprising:

• a wellbore ranging sensor to be disposed on a circumference of a wellbore component operable to rotate about an axis of rotation in a first wellbore;
• a wellbore ranging transmitter to be disposed on the circumference of the wellbore component;
• and
• a controller operable to perform operations comprising:
• rotating the wellbore ranging sensor disposed on the circumference about the axis of rotation to a plurality of distinct sensing positions on the circumference;
• at each sensing position of the wellbore ranging sensor on the circumference, measuring a magnetic field from a second wellbore that is apart from the first wellbore resulting in a plurality of magnetic field measurements at the plurality of distinct sensing positions;
• rotating the wellbore ranging transmitter disposed on the circumference about the axis of rotation to a plurality of distinct transmitting positions on the circumference;
• at each transmitting position of the wellbore ranging transmitter on the circumference, transmitting signals to the second wellbore from the first wellbore resulting in a plurality of ranging transmissions at the plurality of distinct transmitting positions;
• and
• determining a position of the first wellbore relative to the second wellbore using at least a subset of the plurality of magnetic field measurements and a subset of the plurality of ranging transmissions.
