Latest Patents

Hadley's latest patents include a groundbreaking system for well data telemetry by explosions. This innovative data telemetry system is designed for use in plugged exploratory boreholes, allowing for the transmission of measurements of subsurface conditions after long delays through seismic waves. The system incorporates a sensor that detects downhole conditions, such as temperature, and converts these readings into electrical signals. A timer is utilized to detonate explosive charges at predetermined intervals, generating seismic waves that are detected by a seismometer located on the earth's surface.

Another significant patent involves the digital recording of sonic log wavetrains. This invention focuses on the digitization of analog signals produced by a seismic-velocity well logger. The system captures seismic impulses transmitted from a transmitter to a receiver within a logging sonde in a well, with the data being recorded approximately 20 times per second. The recording apparatus digitizes these analog traces by measuring signal amplitudes at intervals of about 10 microseconds, ensuring accurate data storage and monitoring.
