Latest Patents

Chappell holds a patent for his invention titled "Self-degrading organogels." This invention tackles the problem of fluid loss in the oil industry by utilizing a lost circulation material (LCM) that effectively plugs fractures in rock formations. The unique aspect of his invention is that it is engineered to degrade after a specified period, allowing for the unplugging of production zones once drilling is complete. The patent describes a method of gelling an oil-based fluid using a low molecular weight gelator, dibenzylidene sorbitol (DBS). DBS gels exhibit robust plugging behavior and can chemically degrade in the presence of an acid. By incorporating an acid into the system, a self-degrading gel can be synthesized, with the degradation time controllable through the type and concentration of the acid used. Chappell's patent represents a significant advancement in drilling technology.
