The C-1 Anchor is a retrievable double grip tubing anchor designed to anchor the tubing string in tension or compression. When installed with the proper amount of tubing tension, this anchor prevents movement of the tubing string during rod pumping operations. This results in more oil production per pump stroke and in turn extends the life of the pump, rods and tubing and decreases pumping costs. This anchor incorporates an emergency shear release system which is easily adjustable in the field. Anchors are furnished with a total of 22,000 daN (50,000 lbs.) secondary release shears. The C-1 Anchor utilizes drag pads backed up by Inconel springs which results in more positive drag.
