Wireline packers are a time-saving method of 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, Tigre Tierra® Wireline Packers are easily repaired in the field in just minutes.
The features of our wireline packers include:
- Easy field service and repair
- Steel cable reinforced glands
- Our glands retain run-in diameter and hold dimensional stability throughout their service life. Other packers may feature glands strengthened with synthetic fibers. Demand steel cable to protect your investment.
- Incorporated bumper that rests inside the throat of the drill bit
- This positions both glands and protects the drill bit. When one bumper is worn, the gland union can be reversed and a new bumper placed toward the drill bit. The glands are constructed of steel-reinforced natural rubber, while the center tube is made of quality 304 grade stainless steel.
- Compression cap on the Tigre Tierra 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 the wireline packer. The seal tee terminates the drill string and has a one inch NPT port for injection purposes.
- For testing specific zones, a Tigre Tierra Zone Packer can be attached easily to the lower end of the wireline
- The wireline packer is inverted, and the zone packer is connected by using a perforated tube the length of the required test zone. An inflation tube connects the wireline packer and zone packer for simultaneous inflation.
- Stainless steel center tubes
- Standard with every packer so that you never have to worry about pitting or corrosion
- Integral tube scrapers
- Remove grout adhering to the outside of the center tube each time the packer is deflated.
- Best ratio of through-pipe I.D. to packer O.D. in the industry
- Flow rates are higher due to larger I.D. center tubes.
