Title: **Vladimir Dubinksy: Innovator in Shear Velocity Measurement Technology**

Introduction

Vladimir Dubinksy is a talented inventor based in Houston, Texas, with a focus on advanced technologies related to drilling and measurement methods. He has registered a total of two patents, showcasing his expertise in the field of logging tools used for assessing the geological formations encountered during drilling operations.

Latest Patents

Among his notable patents is the invention titled "Method and apparatus for LWD shear velocity measurement." This innovative logging tool incorporates a transmitter situated on a drilling collar designed to excite a quadrupole signal within a borehole being drilled by a drill bit. Key features of this invention include the operation of the transmitter at frequencies below the cut-off frequency of the quadrupole collar mode, allowing the received signal to predominantly reflect the formation quadrupole mode, which aligns closely with the formation shear velocity at lower frequencies. The transmitter is structured with eight equal sectors of a piezoelectric cylinder mounted on the rim of the drilling collar. The cut-off frequency is primarily influenced by the thickness of the drilling collar. Additionally, the technology allows the transmitter to produce both collar mode and formation mode signals, with processing capabilities to filter out the collar mode.
