摘要： A method and apparatus for determining a parameter of interest of an earth formation during drilling of a borehole. A first toroidal coil antenna induces a current along a path that includes a bottomhole assembly and the formation. A second toroidal coil antenna disposed at the drillbit and oriented at a non-zero angle to the longitudinal axis of the bottomhole assembly measures an electrical signal resulting from the current, the electrical signal being a parameter of interest of the formations.

摘要： A resistivity sub including a resistivity sensor forms part of a bottom hole drilling assembly. The sensor is maintained at a substantially fixed offset from the wall of a borehole during drilling operations by, for example, a stabilizer. In WBM, galvanic sensors may be used, with or without commonly used focusing methods, for obtaining a resistivity image of the borehole wall. In OBM, capacitive coupling may be used. The apparatus is capable of using other types of sensors, such as induction, MPR, shielded dipole, quadrupole, and GPR sensors. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b)
