Latest Patents
One of his latest patents is titled "Apparatus and method for resistivity measurements during rotational drilling." This invention includes a resistivity sub that incorporates a resistivity sensor as part of a bottom hole drilling assembly. The sensor is designed to maintain a substantially fixed offset from the borehole wall during drilling operations, utilizing a stabilizer. In water-based mud (WBM), galvanic sensors may be employed, with or without focusing methods, to obtain a resistivity image of the borehole wall. In oil-based mud (OBM), capacitive coupling can be utilized. The apparatus is versatile, capable of using various types of sensors, including induction, MPR, shielded dipole, quadrupole, and GPR sensors. This abstract serves to provide a clear understanding of the technical disclosure without limiting the scope of the claims.
