Latest Patents
One of his latest patents is the "Heave Compensated Wireline Logging Winch System and Method of Use." This invention features a computer-controlled system that compensates for wave motion effects on floating installations performing wireline logging measurements. The system includes a wireline winch and cable with a logging measurement tool attached, installed on a floating installation. It measures vessel vertical movement and adjusts the speed of the wireline cable to ensure controlled logging data acquisition. Any errors in compensation are detected by a depth measurement system, which adjusts the true depth of the logging tool measurements.
Another significant patent is the "Method and Apparatus for Predicting Peak Voltage of a Cable Conveyed Tool." This invention provides a method for predicting peak voltage at the load end of a power transmission cable where direct measurement is impractical. The method samples current and voltage waveforms at the power supply end, estimating a current function that accounts for various factors. This innovation has been particularly useful in oil well logging, ensuring proper tool performance by predicting peak voltage at the tools.
