Aardvark Wireline Packer* is a patented, 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.
Our wireline packers incorporate a 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.
A 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.
