Latest Patents

One of his latest patents is a "Method and apparatus for measuring subsidence." This invention relates to a method and apparatus for measuring subsidence by evaluating the distance between radioactive markers that have previously been implanted in the formation traversed by a borehole. The apparatus comprises an elongate body containing at least two nuclear detection assemblies, which are spaced apart along the longitudinal axis of the body. Each detection assembly includes at least one position-sensitive detector for detecting position along the longitudinal axis of the body. Measurements are performed while the apparatus is held stationary opposite the markers.

Another significant patent is the "Device for placing a radioactive source in a formation through which a borehole passes." This device includes a gun barrel, a bullet containing a radioactive source engaged in the barrel, and an explosive device for propelling the bullet towards the formation. The device further includes two items that reduce the speed at which the bullet penetrates into the formation. These items are a spacer, placed in the barrel between the bullet and the explosive device, and a braking shield placed at the port end of the barrel. The spacer reduces the effect of the gases produced by the explosive device upon detonation. The braking shield is entrained with the fired bullet, producing drag that also acts to retard the forward propulsion of the bullet. The shield is designed to break away from the bullet upon formation impact, further reducing the kinetic energy of the bullet. This invention is particularly applicable to soft formations.
