Title: Innovations by Pierre A Moulin
Introduction
Pierre A Moulin is a notable inventor based in Chaville, France. He has made significant contributions to the field of technology, particularly in the area of geological formation analysis and gyroscopic instruments. With a total of 5 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method and apparatus for determining formation resistivity in a cased borehole. This invention involves a method of determining the resistivity of a geological formation through which a metal-cased borehole passes. It utilizes at least three electrodes in contact with the casing, spaced apart in the longitudinal direction of the borehole. To eliminate the effects of differences between the two sections of casing delimited by the electrodes, a circuit connected to the electrodes forms a Wheatstone bridge, with the casing sections constituting two of the resistances in the circuit.
Another significant patent is related to motion compensation apparatus and method for gyroscopic instruments. This invention measures motion signals of gyroscopes in downhole instruments used to determine the heading of a borehole. The illustrative embodiment includes a measuring-while-drilling system that can experience motion even while the drill string is suspended. It employs accelerometer and magnetometer data along three orthogonal axes to determine the rotation vector of the probe and the heading of the drill string.
