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for logging the density of a gravel pack installation in a drill hole while the gravel pack installation tool is being withdrawn from the drill hole.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.
Claims26
A method for evaluating the density of the material surrounding a drill hole in the earth's surface comprising the steps of:
- a. attaching a logging device to a material installation tool for installing material into the area surrounding the dril hole;
- b. initiating a material installation process;
- c. obtaining a density log of the installed material as the material installation tool is being moved through the drill hole;
- and
- d. evaluating the density log of the installed material.
An apparatus for evaluating the density of the material surrounding a drill hole in the earth's surface comprising:
- a. a material installation tool for installing material into the area surrounding the drill hole;
- and
- b. logging means attached to said material installation tool for logging a density log of the installed material surrounding the drill hole while said material installation tool is being moved through the drill hole.
