Latest Patents

Hemrick's latest inventions include two groundbreaking patents. The first is a patent for "Cement having stress-indicating properties." This system and method involve a unique cement mixture, combined with water, that solidifies while incorporating a stress measuring-medium with piezospectroscopic properties. The medium directly measures in situ stress within the cement mixture when stimulated by light.

The second patent is for a "Stress sensor for cement or fluid applications." This new system utilizes a non-destructive sheath that envelops a tubular structure, which is in contact with the subterranean rock formation. The system is designed to sense expansive changes within the rock formation using an embedded fiber optic. This fiber optic transmits and receives light to measure hydrostatic stress, providing accurate readings without disrupting the tubular structure or considering acoustical effects.
