Latest Patents

Pleun holds two patents, reflecting his expertise and innovative spirit. His latest inventions include:

1. **Steerable Soil Penetration System**: This groundbreaking system features a steerable penetration head designed to compact surrounding soil rather than cut it away. It is connected to elongate flexible tubing, allowing for variable orientation of the head relative to the tubing. The design includes a narrow annulus surrounding the tubing to inhibit buckling and protect the pierced hole from collapsing. Additionally, the tubing can be circumferentially expanded post-piercing to enhance the hole's width and provide permanent lining.

2. **Obtaining an Image of an Underground Formation**: This method focuses on creating an image of the underground formation around a borehole. It involves activating an omnidirectional seismic source within the borehole, while a three-component receiver records the reflected energy from the formation. By computing the direction of this returned energy in relation to two-way travel time, the method efficiently attributes data to selected points in the formation, ultimately forming a comprehensive image of the subsurface reflectors.
