Abstract:
Methods may include conveying a BHA comprising magnetic material in the borehole to a first borehole depth; using a magnetic sensor disposed on the BHA to produce a first magnetic measurement of a component of a magnetic field at the first borehole depth, the magnetic field including an axial component of the magnetic field oriented along a longitudinal axis of the BHA and a plurality of non-axial components unaligned with the axial component, wherein the magnetic field is affected by the magnetic material and wherein the first magnetic measurement is representative of at least one non-axial component of the plurality; estimating the axial component at the first borehole depth in dependence upon the first magnetic measurement; estimating an azimuth of the BHA at the first borehole depth using the axial component; and controlling drilling operations with the BHA in in dependence upon the azimuth.

Claim (Index 35):
An apparatus for conducting drilling operations, the apparatus comprising:\n a bottomhole assembly (BHA) comprising magnetic material configured to be conveyed into a borehole intersecting an earth formation; a first sensor on the BHA configured to produce a first measurement of a component of a magnetic field at a first borehole depth, the magnetic field including an axial component of the magnetic field oriented along a longitudinal axis of the BHA and a plurality of non-axial components of the magnetic field unaligned with the axial component, wherein the magnetic field is affected by the magnetic material and wherein the first measurement is representative of at least one non-axial component of the plurality; and at least one processor configured to:\n estimate the axial component at the first borehole depth in dependence upon the first measurement; \n estimate an azimuth of at least a part of the BHA at the first borehole depth using the axial component; and \n control drilling operations with the BHA in in dependence upon the azimuth.
