Patent GB-8814926-D0 (GB)
Title: Surveying of boreholes
IPC: G01V3/26
Filed: 1988-06-23
Abstract: A method of deriving the true magnitude of the terrestial magnetic field in the direction of the longitudinal axis of a borehole at a region of the borehole occupied by an instrumentation package equipped with magnetic vector measuring means for measuring the lateral magnetic vectors Bx and By and further equipped with gravitational vector measuring means for measuring each of the three gravitational vectors Gx, Gy, and GZ. The method comprises the steps of performing said measurements of the magnetic vectors and the gravitational vectors and from said vector measurements solving the equation:-  Bze = (BVe.Ge - Bx.Gx - By.Gy) / Gz where BVe is the vertical component of the terrestial magnetic field at the location of the borehole, and Ge is the terrestial gravity field. The terrestial gravity field Ge may be derived as the square root of the sum of the individual squares of the individual gravity vectors Gx, Gy and Gz, according to the equation:-  Ge = (Gx<2> + Gy<2> + Gz<2>) <1/2 > . The invention is based on the assumption that the vector measurements, and in particular the lateral magnetic vectors, are substantially uncorrupted by the drillstring or the bottom-hole assembly.
