Title: The Innovative Contributions of Anthony W Russell
Introduction
Anthony W Russell is a notable inventor based in Cheltenham, GB, recognized for his significant contributions to the field of borehole surveying. With a total of 15 patents to his name, Russell has developed innovative methods and apparatuses that enhance the efficiency and accuracy of borehole drilling and surveying.
Latest Patents
One of Russell's latest patents focuses on borehole surveying, which involves a method and apparatus designed for use in surveying boreholes. This method includes providing an instrument package at the leading end of a drillstring, which consists of first and second single-axis sensors. The first sensor is an accelerometer, while the second sensor can be a magnetic fluxgate or a rate gyro. The drillstring is rotated, allowing the first sensor to derive the inclination angle and the second sensor to determine the azimuth angle of the drillstring.
Another significant patent by Russell involves a borehole drilling and survey assembly. This assembly includes a drill string made of magnetic material, a non-magnetic drill collar, and a non-magnetic rotary drilling system equipped with a drill bit. A near-bit survey instrument is strategically placed in the rotary drilling system, while a second survey instrument is located in the drill collar. These instruments measure the local values of the earth's magnetic components along the borehole axis, processing these values to eliminate the magnetic effects of the drillstring. Additionally, the survey instruments can measure gravity vector components to derive the borehole heading.
