Methods and apparatus for determining dynamic flow characteristics of production fluids in a well bore
In the representative embodiments of the new and improved methods and apparatus disclosed, a well tool incorporating the principles of the present invention is arranged for selectively discharging discrete minor quantities of a first radioactive tracer and of a second radioactive tracer. When the tool is stationed in a production well, upon discharge of whichever one of the two tracers that is believed to be miscible in the continuous-phase fluid at that depth location, radiation detectors arranged at spaced locations on the tool respond to provide one or more measurements of the level of radioactivity in the well bore fluids from which one or more dynamic flow characteristics of the continuous-phase fluid at that depth location may be determined.
