This bit caught my eye
Unlike other gases, helium is more soluble in hot water than in cold water. Therefore, as reservoir water is heated, it scavenges helium which migrates upwardly along gas permeable zones of weakness created by a cooling magmatic body. As a drill bit penetrates through conjugate fractures adjacent to a potential reservoir zone, the helium charged fluids in these fractures mix with the drilling mud and are transported to the surface where they are detected.
