Tigre Tierra® Inflatable Packers, designed and manufactured
by Aardvark, range from simple fixed-head balloon packers to steel-reinforced
sliding-head Viton and stainless steel monitoring systems with
multiple transducers and pumps. In addition, we offer our patented
Tigre Tierra® Wireline Packer Systems for permeability testing
during core drilling. Aardvark also carries a complete line of
packer-related accessories to meet your custom needs.
All of our sliding-head packer components thread together for ease
of service in the field, and are designed modularly. This modular
feature allows multiple packers to be installed in a single borehole
to isolate various zones.
Many types of test and monitoring equipment can be incorporated
into a Tigre Tierra® Packer System, including transducers,
thermistors, conductivity probes, pH probes, injection ports, electric
submersible pumps, bladder pumps, vertical turbine pumps, and piston
pumps.
All Tigre Tierra® Sliding-Head Packers use steel reinforced
glands for durability and resistance to cutting and abrasion. Steel
reinforced natural rubber assures positive sealing in rough, irregular
boreholes, and excellent memory in returning to at rest diameters.
The reinforced gland also features uniform expansion over its entire
length, and is extremely durable in open boreholes. The gland is
able to double its run-in diameter so that the same packer can
be used in a wide range of open or cased borehole sizes.
Construction options include stainless steel heads and glands that
can be wrapped with Nitrile, Neoprene, or EPDM. Single and multiple
packer systems are available with or without pumps and other testing
equipment for wells of 1.5 to 13 inches, open or cased.
Feed-Through Systems
Whenever auxiliary equipment is used in a packer system, electric
or pneumatic leads must be incorporated into the packer to access
the instruments. Because of the Tigre Tierra® Packer’s
unique modular design, most feed-throughs can be built directly
into the packers heads. In-line adapters also can be incorporated
for more complex systems.
