The optimum concentration of Lubra-Glide beads is ten (10) pounds per barrel. The volume of fluid to be treated is calculated based on the volume necessary to cover the open hole from the bottom of the hole to a point approximately two hundred (200) feet above the kick-off point in the open hole. If the kick off point is already behind casing, then the entire open hole volume should be treated.
Example: In a 12 ¼ hole the approximate volume would be 150 bbls per 1000 feet. At a minimum, a 10% allowance for washout is included. A minimum volume therefore of 165 bbls treated at 10 ppb would require 1650 pounds (33 sacks) of product per thousand feet. If you are aware of that being a larger percent based on well site information, adjust the volume accordingly.
