Latest Patents

Wisler's latest patents include a "System for monitoring formation spontaneous potential and polarization." This invention utilizes an electrode insulated from and mounted to the outside of a drill collar in a drill string positioned in a borehole. It measures formation spontaneous potential by connecting a current measuring device, such as an ammeter, through a variable ammeter resistor and a switch. The ammeter measures current flow from the formation along the borehole walls to determine the spontaneous potential at various points while drilling. The switch in the ammeter circuit is interrupted at a pre-selected rate, and the ammeter current signal is processed through a lock-in amplifier to cancel random noise, ensuring accurate measurements of small currents indicative of spontaneous potentials.

Another significant patent is for "Electrical resistivity measurement of a flowing drilling fluid using a high permeability ferrite core." This invention combines a ferrite core with a magnetic coil encircling it, positioned in a sub just above the drill bit. The core's gap lies across a recess region in the sub's outer wall, allowing drilling fluids to flow along its surface. A constant current or voltage is applied to the coil, producing measurable back emf indicative of the drilling fluid's resistivity. This innovation allows for real-time monitoring of drilling fluid resistivity, enhancing drilling efficiency.
