Latest Patents

One of his latest patents is titled "Remote digitization of electromagnetic telemetry signal." This invention involves a digitizing apparatus designed to transmit electromagnetic telemetry signals, which facilitates drilling operations. The apparatus includes a local receiver and one or more remote transmitters. The method employed uses the remote transmitter to measure electric potential between ground stakes positioned at a distance from the local receiver. The local receiver is connected to a surface receiver located near a drilling rig. The remote transmitter converts the electric potential into a digital signal and transmits it wirelessly to the local receiver, which then converts the digital signal into an analog signal for processing.

Another significant patent by Down is "Downhole reception and transmission of electromagnetic data telemetry signals." This invention features a retrievable receiver for electromagnetic telemetry signals originating from one wellbore and located in another. The receiver utilizes the casing of the second wellbore as an antenna. A signal pickup unit is placed on a multi-conductor wireline in the second wellbore, equipped with sensors for detecting signals at various locations. The signal reception can be optimized by adjusting the wireline's position or selecting specific sensors for receiving telemetry signals.
