ABSTRACT:
A rod guide with removable vanes provides the capability of using one wear-resistant material for the erodable volume of the rod guide and another, stock material for the body that holds the vanes. When the vanes of the rod guide are expended, they are removed and replaced and the body is reused. In this way, sucker rod segments can be quickly and easily refurbished in the field with significant savings in transport time. High value wear-resistant materials are placed where the wear occurs and the remainder of the rod guide is made of a material that can be used for an extended period of time in the harsh down-hole environment.
