Abstract
Magnetic locator systems and methods of using same at a wellhead are described. The magnetic locator systems include a magnetic field generator on an oilfield tool component, such as a deployment bar, adapted to be moved through an oilfield pressure control component, such as a blow-out preventer, lubricator, riser pipe, or wellhead, and a magnetic field sensor located outside of the pressure control component adapted to detect the magnetic field and thus the position of the tool component in the pressure control component. The systems and methods of the invention provide safer and more efficient operation of oil and gas well pressure control systems. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
