Latest Patents

Weltzin's latest patents include an "Apparatus and method for evaluating a wellbore, in particular a casing thereof." This innovative apparatus is designed to evaluate a wellbore while drilling. It includes a logging tool held on a drill string, which is capable of obtaining data from the wellbore as the drill string moves uphole and out of the wellbore. The logging tool features a memory for storing the obtained data and an on-board power supply battery. A computer positioned at the surface level of the wellbore is designed to retrieve data from the memory when the logging tool is also at the surface. The logging tool can operate in a low-power sleep mode, with the data obtaining and storing function disabled. The computer can transmit a wake-up signal downhole to activate the data function just before tripping out the drill string. The wake-up signal is preferably a mud pulse signal sent through the drilling fluid used during the drilling process. Another patent is for a "Centralizer," which includes a centralizer body situated at the outer surface of a pipe string, such as casing or liner. This centralizer body is designed with a plurality of outer centralizer blades arranged at an incline to the longitudinal axis. The centralizer body features a separate split inner tube secured to the pipe string by means of a press fit, with low friction materials used for both the inner surface of the centralizer body and the separate center tube.
