ABSTRACT:
An apparatus and method are disclosed for logging the density of a gravel pack installation in a drill hole while the gravel pack installation tool is being withdrawn from the drill hole. After the apparatus is recovered at the earth's surface, the density log is recovered by means of a dedicated surface readout module. The logged data of the density of the gravel packed zone is examined for voids in the gravel pack. If any such void is indicated from the data, remedial action can be taken promptly while the gravel pack equipment is still at the drill hole site.
