Don-Nan Slimhole Tubing Anchor

Flexible tubing placement

Deploy anchor at any time

In contrast to a standard anchor, the slimhole tubing anchor can be deployed at any point in the well in relation to the perforations. 

The ability to run the slimhole tubing anchor below perforations enables you to pump from the point in the well that maximizes oil production and minimizes gas interference. The tubing can be anchored at the deepest point in the string, eliminating the need for tubing below the anchor. This placement reduces downhole assembly wear and tubing fatigue caused by tubing movement. In addition, tapered connections prevent anchor seizure by diverting solids that might otherwise accumulate in the anchor.

The improved design minimizes solids buildup in the anchor, and the smaller OD improves gas flow past the anchor.

Move anchor placement for greater flexibility

If the slimhole tubing anchor is placed above perforations, its design provides the benefit of increasing the width of the annulus between the OD of the anchor and the ID of the casing.

Benefits

  • Improves pump efficiency
  • Reduces solids accumulation in the anchor
  • Enhances gas flow up the tubing or casing annulus

Features

  • Ability to set anchor in or below perforations
  • Smaller OD
  • Tapered connections
  • Adjustable shear rating
  • Slip protection drag blocks
