Latest Patents

One of his latest patents is titled "Cement data telemetry via drill string." This method involves acquiring data through a receiver mounted in a drill string during its descent into a wellbore. The data collected is essential for evaluating the characteristics of cement used in the drilling process. The method includes buffering the acquired data to a memory device in the drill string and transmitting it via mud-pulse telemetry while pumping drilling fluid. Another significant patent is "Data transmission during drilling," which facilitates efficient data transfer during drilling operations. This technique allows for real-time sensor data to be transmitted to a surface location while the drill bit is engaged in cutting a borehole. The transmission of current sensor data is paused when the drill bit is off bottom, allowing previously recorded data to be sent uphole.
