A method for determining orientation of an electrical resistivity boundary in a wellbore includes using measurements of an electromagnetic property of formations traversed by the wellbore at at least one axial spacing between a multiaxial electromagnetic transmitter and a multiaxial electromagnetic receiver, and determining a symmetrized angle using measurements of the electromagnetic property made using receiver components transverse to a well logging instrument axis and a transmitter component along the axis. At least a relative orientation of the electrical boundary with respect to an orientation of the well logging instrument is determined using the symmetrized angle.

Generalized directional measurements and using symmetrized and anti-symmetrized angles to indicate orientation of anisotropy and formation boundaries

This invention discloses a stackable connector assembly, which includes a first connector, a second connector, a shielding member, a contact member, and a ground member. The second connector is placed above the first connector. The shielding member is covered on the first connector. The contact member is used for connecting the shielding member and the ground member. This structure can reduce the electromagnetic radiation from the first connector.
