A packer is a device for sealing off a drill hole when you want to examine or inject a formation, either in the total length or in a part of the hole. When sealing off the hole it is possible to pump in a liquid under pressure (concrete paste or water) into any cracks. The hole is sealed off by a sleeve being expanded against the wall of the hole. The liquid is pressed down into the hole through a piping in the packer. The piping is provided with either a check valve or a stop valve.
The packer’s efficiency depends on its construction and the appearance of the formation in which the packer is placed. There are of two kinds of packers: compressible and inflatable. There are single-use packers and reusable packers and there are single packers and double packers.
