Wire-Line Packer wire-line-packe

Star Wireline Packer System is a time-saving method for conducting permeability testing during core drilling.The test is carried out with the drill string in place, reducing the time required to test in open or unstable formations. Available for all makes of wireline core barrels (N, H and P), Star Wireline packers are easily repaired in the field in just minutes The wireline packers incorporate a bumper that rests inside the throat of the drill bit.This positions both packers and protects the drill bit. A compression cap ''T'' on the Seal Tee Assembly prevents pressure loss around the composite cable during testing.The composite cable itself is composed of a high pressure nylon tube for inflation and a cable to lower and retrieve star wireline packer.
