Title: Richard Hefelfinger: Innovator in Seismic Shock Attenuation
Introduction
Richard Hefelfinger is a notable inventor based in Grand Junction, Colorado. He has made significant contributions to the field of oil shale extraction through his innovative methods. His work focuses on enhancing safety and efficiency in the process of detonating explosives in oil shale retorts.
Latest Patents
Hefelfinger holds a patent for a method designed to attenuate seismic shock generated from detonating explosives in in-situ oil shale retorts. The patent describes a process where voids are excavated at retort sites, and explosives are strategically placed in the unfragmented formation. Upon detonation, the explosion creates seismic shock waves that can potentially damage sensitive equipment. Hefelfinger's method involves shielding this equipment by placing it in the shadow of a fragmented mass, which effectively reduces the impact of the seismic waves.
