The double-acting, Logan Bi-Directional Coiled Tubing Energizer is an impact enhancement tool designed for slim holes (generally a wellbore less than 6 inches in diameter). Its function is to supply intensified impact during the jarring operation by providing or enhancing jar impact from energy stored within its oil-filled compression chambers. It also functions as a shock absorber that prevents impact damage to the tool string at the bottom of the coil, which is often referred to as the bottom hole assembly or BHA. A Logan Bi-Directional Coiled Tubing Energizer is recommended any time a Logan Bi-Directional Coiled Tubing Jar is included in the work string.
