ABSTRACT:
The present invention is a density meter which includes a well logging sonde that is inserted into a borehole traversing an earthen formation. The sonde includes within it a source which emits gamma rays into the borehole fluid and a detector assembly which detects gamma rays from the borehole fluid and provides a count signal corresponding to a count of the detected gamma rays. A caliper is also located in the sonde and it continually measures the diameter of the borehole as the sonde moves through the borehole and provides a caliper signal corresponding to the diameter measurement. A cable connected to the detector assembly and to the caliper conveys the count signal and a caliper signal to the surface where surface electronics includes apparatus which processes the count signal and the caliper signal to provide a signal corresponding to the density of the fluid in the borehole.
