Purpose

To ease friction by centering the tool string.

Description

Roller stem is made up in short sections usually two feet in length with upper and lower thread connections. Slots cut at 450 to one another are cut in the body lengthwise.

Rollers are mounted in the slots with the use of a roller shaft placed at 90. The rollers used have an outside diameter larger than the body of the roller stem.

This allows the tool string to have a gliding effect.

Application

Used in wells with great degrees of deviation, slant wells and wells containing internal coated tubing.

Operation

The roller stem is normally placed midway in the tool string. In some applications placement is near the top and bottom of the tool string.

Precautions

After each use inspect rollers for cracks, wear or chips.
