Title: The Innovations of Frederick A. Stone
Introduction
Frederick A. Stone is a notable inventor based in Durham, Connecticut, recognized for his contributions to the field of drilling technology. With a total of seven patents to his name, he has made significant advancements that enhance the efficiency and accuracy of borehole measurements.
Latest Patents
Among his latest patents is a method of decoding Measurement While Drilling (MWD) signals using annular pressure signals. This innovative approach allows for obtaining borehole measurements by decoding mud pulse telemetry signals from the annulus pressure signals, rather than the traditional standpipe pressure signals. The method enhances data-bearing signals by combining annulus and standpipe pressure signals through addition, multiplication, or correlation techniques. Another significant patent involves the detection and correction of magnetic interference in borehole drilling. This method addresses errors in azimuth determination caused by variations in the earth's magnetic field, distinguishing between variations caused by the drillstring and those from external sources. By correcting only for errors caused by the drillstring, the method improves accuracy in azimuth determination based on dip angle data.
