Abstract
A system and method for performing packer testing in subterranean wells using air to remove liquids from an isolated section of the well. Packers are inflated to isolate a section of the well. Air is introduced into the tubing, which creates a vacuum in the tubing. The vacuum pulls liquids out of the isolated zone and up to the surface and out of the well. The vacuum empties the isolated zone so that the zone can be tested.
Claims6
A method of performing packer testing comprising the following steps:
- lowering tubing into a pilot hole, said tubing having a pipe at a lower end of the tubing wherein a portion of said pipe is perforated;
- lowering a first and second packer into the pilot hole;
- inflating said packers using a packer inflate hose that is in fluid communication with said packers;
- upon inflation, said packers forming a seal against the inside wall of the pilot hole and the outer wall of the pipe;
- the inflated packers forming an isolated zone between the first and second packer;
- the isolated zone being fluidly isolated from a remainder of the pilot hole;
- removing materials from the isolated zone by introducing air into the tubing via an air development inlet in fluid communication with the tubing, an air development hose in fluid communication with the air development inlet, and an air compressor in fluid communication with the air development hose.
