ABSTRACT:
Well is first logged with gamma ray detection system to provide a base log. Fluid containing salt of potassium, uranium or thorium is then injected into the well opposite the interval of interest. When the well head pressure is increased, some of the injected fluid will move into the fracture or other highly permeable localized zones. The gamma ray detection system is then run again one or more times through the well to provide a log which is compared with the base log. The fracture is detected by localized drastically higher readings observed on the repeat run of the gamma ray detection logging system.
