“Mechanical” style Inflatable Packer assembly

“Fixed Head” style Inflatable Packer assembly

“Sliding Head” style inflatable Packer assembly

Composite Cable consists of 3/32-inch (2.4 mm) Steel Cable for hoisting, 3/16-inch (4.8 mm) Inflation Tube wrapped in a 7/16-inch (11.1 mm) OD protective x flexible PVC Jacket, best used with our Wireline (coring) Packers

Grout Packers – feature larger ID Center Tubes, Grout Scraping Seals and inflation up to 1,800 psi (124 bar)

Environmental Packers – flexibility in design allows for multiple Sampling Tubes

Inflatable Packers - Come in three (3) fundamentally different configurations:

The first is the Sliding Head Style Packer, where one head (end) is fixed. In our design, the fixed head is threaded on the end of a Center Tube, also known as a Mandrel.

The opposite end is designed to slide up the Center Tube as the packer becomes inflated. Seals, O-Rings and Scrapers (Grout Seals) keep the center tube clean from debris. This style allows for a broader range of inflation diameters.

The second - Fixed End Packers are just that, meaning both ends of the packer are fixed.

As inflation pressure is increased the rubber element expands much like a balloon. These types are commonly used in Environmental applications as they can be modified greatly in their configuration. More pass thru (larger center tube) options are available in these types of packers and we can vary the rubber compounds to include Viton, EPDM, Neoprene amongst others.

The Fixed End Packers are sized closely to the diameter they are intended to be used. For example, in a 4-inch (HW or HWT) diameter casing/ borehole, we would suggest a packer OD of 3-1/4-inches (83 mm)

Third - Mechanical Packer is designed after the common well seal. A rubber element is sandwiched between two discs. A tightening rod is screwed down compressing the rubber element outward creating a seal in the casing.

These should be sized even closer to the bore hole or casing ID as then the fixed end packers are - for example…a 4-inch (HW or HWT) casing/ borehole, the mechanical packer OD should be 3-7/8-inches (98.4 mm).

Wireline Packers are available in support of deep coring applications as are Straddle style Packers (by connecting them down-hole) to isolate both the top and bottom of specific zones in a cased or open bore hole.
