Latest Patents

One of his latest patents is a method for determining the dip angle of geological formations traversed. This method involves transmitting acoustic signals in a direction substantially perpendicular to the borehole axis from different levels of at least three determined generatrices of the borehole wall. Reflected acoustic signals are received from the same direction at different levels of these generatrices. A train of signals is derived from each reflected acoustic signal, and at least a group of significant elements of this signal train is selected. The groups of significant elements of the signals obtained for the different generatrices are correlated. The interval between signal trains corresponding to the maximum correlation corresponds to one and the same geological formation and is representative of the dip angle of this formation.

Another significant patent is a method and device with adjustable focusing for measuring electric potential. This method comprises determining the variation of the electric potential on both sides of a central electrode in a borehole. It involves detecting the two levels of the borehole where the potential gradient is zero and measuring the electric resistivity of the geological formation between these two levels.
