Wireline Packer System is a time- saving method for carrying out permeability testing while the core drilling is done. The Test is done by using the drill string in place and thereby reducing the time that is needed to be tested in open or unstable formations. Wireline Packers, which consist of N,H and P measures, could be easily and shortly repaired in the field. The wireline packers incorporate a bumper that rests inside the throat of the drill bit. This also protects both packer and drill bit. A compression cap situated on the Wireline Packer protects the pressure around the composite cable. The function of the composite cable,which is made of durable product against to excessive pressure,is that it inflates and lowers, retrieves the wireline packer.

Carrying out the permeability Test;

· Take out the inner tube assembly.

· Increase drill string off bottom by putting it on the intended test zone.

· Build the seal tee assembly ay top of drill string.

· Decrease wireline packer assembly and get the compression tightened.

· Connect composite cable to center of compressed fluid.

· Inflate wireline packer.

· Inject water by means of seal tee assembly wireline rods and place packers into the intended test

. You can carry out the permeability test

· Having carried out the Test, wireline head and wireline packer are removed.

· Leave the innertube assembly into the well.

· You can continue to drill after lowering the drill string .
