Abstract
Downhole orientation sensing with a nuclear spin gyroscope. A method of sensing orientation of an instrument assembly in a subterranean well can include incorporating an atomic comagnetometer and an optical source into the instrument assembly, and installing the instrument assembly in the well. A downhole orientation sensing system for use in conjunction with a subterranean well can include a downhole instrument assembly positioned in the well, the instrument assembly including an atomic comagnetometer and an optical source which transmits light to the atomic comagnetometer.
